Type an ID. Watch a container's life come back.
A container with no memory is a container nobody can trust.
The single biggest obstacle to container reuse is not technology or economics. It is that a used container arrives with no verifiable history, so every buyer has to take somebody's word for what is inside the polymer.
The passport is our partial answer. Every cage that passes through this yard gets an ID stamped on the lower rail, and a record opened against it: manufacturer, first fill, every cargo we know about, every wash cycle and route, every leak test, every weld repair, road miles and the current grade.
It is partial because it only covers containers that have been here. A tote arriving from a yard that keeps no records starts its passport on the day we meet it, with everything before that marked unknown — which is honest, and frustrating.

What people ask about this.
Is the tracer on this page showing real records?
No — it runs on a demo dataset so that anybody can see what a passport looks like without owning one of our containers. The histories it generates are representative, not real.
Live records for a container you own are emailed with its delivery ticket. If you have the ID and want the file, put it in the message field of any form on this site and we will pull it.
Where exactly is the ID stamped?
On the lower cage rail, right-hand side as you stand facing the outlet valve. It is a paint-filled stamp, deliberately placed where a forklift is unlikely to reach it.
If it is painted over or corroded, send us a photograph of the UN plate and the bottle date wheel and we can usually find the record from those.
Can I use this for my own fleet?
Yes. Fleet reconditioning customers get their own asset tags cross-referenced to our passport IDs, so a query against either one returns the same record.
Several customers have replaced their internal container tracking with it, which was not the original intention but is a reasonable outcome.
What happens to the record when a container is scrapped?
It is closed, not deleted, with the disposition and recovered weights recorded against it. Those closing entries are what the diversion certificates are built from.

| D — Reclaim | Failed test or structure | Not resold | 16 | 9 | Not applicable — this is the floor |
Price index is relative to Grade A food at 100, not a quote. The absolute level moves with resin, scrap steel, freight rates and the agricultural season.

Buying questions, answered at length.
What payment terms do you offer?
Pro forma for a first order, net 30 on account once established, and purchase orders for public buyers as standard.
Quotes are valid thirty days. Beyond that we refresh rather than honour a stale number, in either direction — this market moves with resin, scrap steel and the agricultural season.
Will you tell me to buy something cheaper?
Frequently, and it is commitment seven of our circular pledge: every new-container quote includes the nearest reclaimed option with the carbon difference written out.
We also steer dense cargo from 330s to 275s, site water from Grade A to Grade C, and drinking water away from used bottles entirely.
What is the minimum order, really?
One unit, on every product line. There is no hidden minimum and no 'pallet quantity only' rule.
Freight is what makes single units expensive. Inside our six weekly lanes we will usually fold one tote into a scheduled route rather than quoting LTL, which is why a single-unit order to Toledo costs a fraction of a single-unit order to Dallas.
Can I see the exact units before paying?
Yes, and it is standard rather than a concession. Four photographs per unit plus the cage stamp, tagged to a bay number, emailed before payment.
This started as a way of ending a recurring argument about Grade B expectations. It turned into our most effective quality control, because an inspector who knows the photograph goes to the customer grades more conservatively.
How do I know the grade is honest?
Because the disqualifiers are published. A Grade A food unit drops to Grade A washed if there is more than one prior cargo, if the declaration is missing, if third-rinse conductivity is out of tolerance, if the scope shows film, or if the odour check fails.
Ask any supplier what would disqualify a unit from the grade they just sold you. A supplier who cannot answer immediately does not have a grading system.
What happens if a unit is not as described?
We replace it, re-grade and refund the difference, or collect it and refund in full — your choice, not ours.
We have refunded four units in the last three years. All four were our grading error, and all four customers still buy from us.
Operational questions.
What is the single best way to cut my container cost?
Measure your real cycle time, which is almost always worse than you think. Annual fills divided by fleet size: most operators assume eight turns a year and measure four to five.
Fleet size is throughput multiplied by cycle time, so halving cycle time halves the containers you need. Scheduled collection rather than requested collection is the single biggest lever, and it costs nothing.
Do you ship internationally?
Yes. Steel or plastic pallets to avoid ISPM 15 timber treatment requirements, double-stacked empties because ocean freight is priced per container, and a wash record plus prior-contents documentation in the pack.
Twenty-two units floor-loaded in a 40-foot container, forty-four double-stacked empty. Block and brace properly: ocean movement is far more violent in the vertical and roll axes than road movement.
Why is there no phone number?
Cargo declarations have to be written to be worth anything, a container quote involves nine variables that nobody holds accurately in conversation, and most of our customers are on a forklift rather than at a desk.
Every form submission is read by a person and answered within one business day, usually much sooner. Nothing is agreed that is not written down. For genuinely complex work we will schedule a video call.
Can you deliver without a loading dock?
Yes. Liftgate delivery lowers units to ground level and is standard on agricultural and construction-site work, not an exception.
Arrange it at the quoting stage. A liftgate booked then costs a fraction of one arranged at the door, and a refused delivery costs more than both.
Will you collect my empties?
Free from eight units inside our six weekly lanes, with payment for anything resaleable and a diversion certificate stating unit count, weighed mass and disposition split.
Further out, a collection needs to be close to a full trailer load or matched against a delivery on the same trip. We have never issued a disposal invoice.
How fast can you turn an order around?
Grade B and C from floor stock, usually the same week. Grade A washed, two to five business days. Rebottled, five to ten because bottles are fitted to order. Then add transit for your zone.
Wash bay throughput is about 90 units a day on Route 1 or 2 and 55 on Route 3. In practice turnaround is set by inspection and photography, not by washing.
Freight arithmetic, in one place.

| Pickup with trailer | 2–4 | 4–8 | 2–4 | 8–12 |
Twenty-two is the worst number of totes to order: a 53-foot trailer holds twenty, so twenty-two pays for two trailers to move two containers. We load-plan every multi-unit quote for exactly this reason.
Eight mistakes we watch customers make, repeatedly.
None of these are stupid. All of them are expensive, and every one of them has happened to somebody competent in the last twelve months.
1. Multiplying volume by 8.34 and forgetting specific gravity
A 275-gallon tote of 50% caustic soda grosses 3,637 lb, not 2,420. Forklift capacity ratings, racking beams and warehouse floors all care about the real number. This is the single most common serious miscalculation in liquid handling.
2. Buying Grade A washed for site water
Cosmetic condition has no effect on how well a container holds water for dust suppression. Grade C costs a third as much and lasts exactly as long under that treatment. Roughly half the customers who ask for Grade A are paying for appearance they do not need.
3. Fitting a vented cap for storage
A vented cap is a dispensing device. Left on a stored container it pumps moist air in all winter, and we have opened totes in March with half a litre of condensate sitting on top of the cargo. Solid cap in storage and transit; vent at the point of use.
4. Filling to the brim before a freeze
Water expands about nine percent on freezing and an HDPE bottle will crack at the lower corner near the sump almost every time. Fill water-based cargo to 85% and store where the unit can drain.
5. Reusing the gasket
The cheapest component in the assembly and the most common source of carried-over odour and cross-contamination. Gaskets take a compression set, harden, and hold prior cargo in the elastomer.
6. Ordering twenty-two units
A 53-foot trailer holds twenty. Twenty-two pays for two trailers to move two containers. Tell us if your number is flexible and we will tell you which way to move it.
7. Forcing a buttress thread
S60×6, S70×6 and S75×6 will each start on the others and then bind. Two turns and a stop means the wrong standard, and forcing it crazes the bottle neck permanently.
8. Storing translucent bottles outdoors
UV plus freeze-thaw cycling is what finally kills HDPE. We have measured 10% wall loss on the south face of bottles after five years in the open, with the shadow pattern of the cage printed onto the plastic. Black UV-stabilised bottles outlast translucent ones by three to four times outdoors.
The pages our own staff keep open.
The anatomy of a caged tote, part by part.
A 275-gallon caged IBC looks like one object and is actually five, each with a different lifespan, a different failure mode and a different second-hand value. Knowing which part you are buying is most of what separates a good purchase from an expensive one.
The inner bottle
Blow-moulded HDPE, 42 lb, nominal wall around 2 mm with deliberate thickening at the corners and the sump. It carries the cargo and nothing else. It is the part that ages: UV takes the surface, freeze-thaw cycling takes the corners, aromatic solvents soften the wall, and chemical stress plus mechanical stress together produce crazing. A bottle in indoor service with a compatible cargo will outlive the person who bought it. The same bottle in a Michigan yard, translucent, filled to the brim in November, has about five years.
The steel cage
Tubular galvanised steel, 55 lb, 44 to 54 welded nodes depending on the moulder. It takes every load the bottle cannot: stacking, strapping, forklift abuse, the hydrostatic push of a full bottle against its own walls. Cages outlast bottles roughly three to one, which is why rebottling exists as a trade at all. The failure modes are cracked nodes, a diagonal pushed out of square by impact, and red rust bleeding through a breached galvanising layer at a weld.
The base
Steel, composite, hybrid or timber, 22 to 44 lb. It decides how the unit can be handled and whether it can leave the country. Four-way entry and pallet-jack access are not universal, and a timber base without an ISPM 15 heat-treatment stamp will be stopped at a border. The welds attaching the cage to a steel base are a specific inspection point because a failed base weld makes the whole unit unstable under load with no other visible symptom.
The closures
A 6-inch top cap, a 2-inch discharge valve, the adapter stack at the outlet, and the gaskets. Together they weigh a few pounds, cost a fraction of the assembly, and cause most of the complaints: weeping valves, carried-over odour, cross-threaded adapters, vented caps left on in storage. We replace the valve, cap and gasket on every Grade A unit for exactly this reason — it is the cheapest possible insurance against the most common possible problem.
The markings
The UN plate, the cage stamp, the moulder's date wheel inside the bottle skirt. These are the unit's identity. The plate decides whether it can carry a regulated cargo and until when; the cage stamp is how we can reissue a seven-year service history years after the unit left the yard. A unit with an illegible plate is not scrap — it is a perfectly good container that has lost its licence, and it is priced accordingly.
If you only remember one thing: you are buying a bottle with a date on it, bolted into a cage that will outlive it, with hardware that should be new. Price the bottle, inspect the cage, insist on the hardware.

Specification questions, in detail.
Can a cage be reused with a new bottle?
Yes, and that is what rebottling is: a new blow-moulded HDPE bottle fitted into an inspected cage and base. Cages outlast bottles about three to one, which is why the trade exists.
The cage goes through the same inspection as everything else first — 44 to 54 weld nodes counted individually, diagonals measured, base welds loaded, galvanising checked at the welds. We fitted 4,118 new bottles in 2025. Bench turnaround on contract work is 48 hours.
Do you have 350 and 500 gallon containers?
Yes, as stainless bins rather than caged composites. A 350-gallon square 304 bin is 48 × 42 inches and 55 inches tall with a 420 lb tare; a 500-gallon cylindrical 316L is 52 inches in diameter, 74 tall, 580 lb.
They are the right answer for aggressive acids above SG 1.6, for hot cargo, and for anything where you want a container that will outlive several poly ones. They do not stack, and the trailer count drops to fourteen for the 500s.
What is the heaviest cargo you would put in a reclaimed poly tote?
In practice, 50% caustic soda at SG 1.53 in a 275 — which grosses 3,637 lb — is about where we stop being comfortable, and we check the customer's forklift rating before quoting it.
Sulphuric acid at 93% and SG 1.83 we will not put in poly at all; that is steel or stainless service. The limiting factor is rarely the bottle's burst strength and almost always everything underneath it: forks, beams, floors.
How do I work out whether my cargo is too heavy for a 330?
Multiply litres by specific gravity to get kilograms, or gallons by 8.34 by specific gravity to get pounds, then add the tare — 127 lb for a 275, 145 lb for a 330 — and compare against the maximum gross mass on the UN plate.
The plate figure is the binding one. As a rough guide, cargo above about SG 1.4 belongs in a 275 rather than a 330 simply because the taller bottle puts more mass on the same footprint, and above SG 1.6 you are usually looking at lined steel or stainless rather than poly.
What is the difference between a 275 and a 330, apart from volume?
Height, mostly. Both sit on the same 40 × 48 inch footprint; the 275 is 46 inches tall in the standard build and the 330 is 53. The trailer count is identical at twenty on the floor, which surprises people.
The consequence is density: a 330 full of anything heavy puts more mass on the same square footage, so forklift ratings, racking and floors all need checking against the real figure. For dense cargo, two 275s beat one 330 and a half.
How do I tell which buttress thread I have?
Measure the outside diameter of the male thread: roughly 60 mm is S60×6, 70 mm is S70×6, 75 mm is S75×6. S60×6 is the European norm — Schütz and Werit — and S70×6 covers Mauser and most North American bottles.
The reason this matters is that all three will start on each other and then bind after a turn or two. Two turns and a stop means the wrong standard. Forcing it crazes the bottle neck permanently, and a crazed neck is not repairable.
Which gasket do I need?
EPDM for water, glycols, caustics, fertilisers and most food products. Viton for acids, hydrocarbons, solvents and anything aromatic. PTFE for aggressive oxidisers and where nothing else is rated.
The two expensive errors are EPDM in hydrochloric acid, where it is destroyed in weeks, and EPDM in hydrocarbons, where it swells. If you tell us the cargo we specify the elastomer, and it is on the component list that ships with the unit.

Checks 05 to 09 are where most units lose a grade, and they are all condition of the bottle rather than cleanliness. A container can be surgically clean inside and still be Grade C because of what five Michigan winters did to the outside.
Fourteen stations: what happens between the gate and the truck.
A container that arrives on a Monday morning and leaves as Grade A food on Thursday has been through fourteen stations, and at eight of them it can lose a grade or be pulled out entirely. This is the route, in order.

Nothing comes off the trailer without a named prior cargo in writing. No name, no entry; the load goes back. This is the single rule that protects everything downstream, because one undeclared pesticide tote in a recirculating wash loop can affect a hundred units before anybody smells it.
2 — Exclusion screen
The declared cargo is checked against the published exclusion list. Pesticides, pharmaceutical actives, PFAS formulations, isocyanates, radiological material, fire-affected units and polymerising oils are refused outright, whatever the condition and whatever the price.
3 — Heel drain and measure
Residual cargo is drained, measured and routed to the correct waste stream. Under a gallon is normal. Above five gallons the load is a liquid-waste job rather than a container job, and it is priced or refused as one.
4 — Weigh and log
Yard scale, not a unit count. Every published tonnage on this site traces back to this scale, which is why our disposition table reports weight and units separately and why they do not divide into each other neatly.
5 — Cage and base inspection
Node by node, 44 to 54 of them, counted rather than sampled. Diagonals measured. Base welds loaded and watched. Galvanising checked at the welds, which is where it always goes first.
6 — Bottle condition
Wall thickness at four points, raking light across the whole surface for crazing, sump checked for stress whitening, mid-wall measured for bulge against a datum. This is where most grade losses happen, and none of them are about cleanliness.
7 — Wash route assignment
Decided here, by prior cargo, by an inspector — not at the sales desk by price. A food cargo goes to Route 3 whether the customer asked for it or not; an industrial cargo cannot buy its way onto Route 3.
8 — Wash
Route 1 rinse, Route 2 hot caustic, Route 3 potable triple rinse, or Route 4 to a customer's own written SOP. Temperature, dwell, rinse count and chemistry dosing are logged against the cage ID as it happens, not reconstructed afterwards.
9 — Rinse verification
Third-rinse conductivity against the day's measured supply water, final pH, 360-degree internal scope, and an independent two-operator odour check with the cap off. Any one of them failing sends the unit back to station 8.
10 — Hardware
New gasket on every Grade A and B unit, no exceptions. Valve function-tested and replaced if scored. New cap. Adapter threads checked under a light. Tamper seal on anything food-grade.
11 — Leak test
Pneumatic pressure decay on the complete assembly, under 1 kPa loss in ten minutes. Method, pressure, hold time and measured decay are written to the record — a pass with no numbers behind it is not a leak test.
12 — Grade and passport
The grade is assigned against the published criteria and written to the passport with the cage ID, the wash route, the test dates and the operator who did it. Seven years of retention, reissuable on request.
13 — Photography
Four shots of the actual unit plus the cage stamp, bay number visible. These go to the customer before payment. It started as a way of ending arguments about Grade B and became our best quality control, because an inspector who knows the photograph goes out grades more conservatively.
14 — Bay and load plan
Into one of 168 numbered bays by grade and configuration, then load-planned against trailer capacity. Twenty on the floor, forty double-stacked empty. If your order is twenty-two units, this is the station where somebody emails you to suggest twenty or forty.
What 'food grade' means, and the four things it does not.
This is the phrase that causes the most confusion and the most expensive mistakes in this trade, in both directions: people buy far more than they need, and occasionally people buy something and call it food-grade when it is not.
What it means here
On this site, Grade A — Food means one documented prior cargo, that cargo was a food product, the unit went through Route 3 — the potable triple rinse at 140 to 160 °F with food-safe alkaline chemistry — and it passed third-rinse conductivity against the day's supply water, final pH, a 360-degree internal scope and an independent two-operator odour check. New gasket, new cap, function-tested or new valve, tamper seal fitted, leak tested, photographed, and written to a passport record we keep for seven years.
What it does not mean — 1. It is not a certification
There is no body that stamps a used IBC as food-grade. Any supplier implying otherwise is describing their own internal standard, exactly as we are describing ours. The difference between standards is whether the disqualifiers are published and whether the records come with the unit. Ask both questions of anyone, including us.
2. It does not make the unit allergen-safe
A tote that previously held a dairy, egg or tree-nut-derived product has been washed to the same standard as any other food cargo, and we flag the allergen history explicitly — but washing is not a validated allergen removal process, and we will not pretend it is. If your product carries an allergen claim, buy rebottled. A new bottle has no history to flag.
3. It does not mean 'never held anything industrial'
That is a stricter claim, and it is the actual reason to buy rebottled rather than washed. A new bottle in a reclaimed cage costs 40 to 60 percent more than a washed unit and removes the whole question.
4. It does not transfer to your process automatically
Your own HACCP plan, your filler's requirements and your customer's audit may all demand things beyond the container: a dedicated unit, your own incoming inspection, a specific gasket elastomer, a particular closure, or documentation in a particular format. We will run Route 4 against your written SOP and log every parameter you name, which is usually the cleanest way to satisfy an auditor.
The practical decision
Drinking water, infant or allergen-claim products, high-purity water: rebottled, always. Food ingredient in the same category as the prior cargo, with the declaration in hand: Grade A food is genuinely appropriate and is what it exists for. Anything industrial, agricultural or utility: you are about to overpay by a factor of two or three, and roughly half the people who ask us for food-grade are in this row.
What actually moves the price of a reclaimed tote.
| Driver | Direction | Typical effect | Can you control it? |
|---|---|---|---|
| Grade | A costs more than C | Up to 3× across the range | Yes — most buyers over-specify |
| Wash route required | Route 3 over Route 1 | +18 to +30% | Yes, by naming the real end use |
| New bottle (rebottled) | Up | +40 to +60% over washed | Yes — only food and potable truly need it |
| Quantity against trailer fit | 20, 40, 60 are efficient | ±15% on delivered cost | Yes, and this is the easiest saving |
| Freight zone and lane | Lane beats distance | ±40% on delivered cost | Partly — ask which day we run your lane |
| Season | B and C peak in spring | +15 to +20% March–May | Yes, if your timing is flexible |
| Pallet base specified | Steel or composite over timber | +4 to +20% on the base | Yes |
| New valve and cap | Up | Fixed per unit | Yes — reconditioned hardware is an option on C |
| UN plate in date | Up | +8 to +12% | Only if your cargo is regulated |
| Resin and scrap steel index | Both directions | Moves the whole market | No |
| Diesel | Up with fuel | Freight line only | No |
| Take-back credit on your old units | Down, against the invoice | Offsets part of the order | Yes — ask before you dispose |
We quote containers and freight as separate lines, because a single delivered number hides which of these twelve things you are actually paying for. If a quote you are comparing does not split them, ask.
Lead times, honestly, by grade and quantity.
| Order | Grade A food | Grade A washed | Grade B | Grade C | Rebottled |
|---|---|---|---|---|---|
| 1–4 units | 2–4 days | Same or next day | Same or next day | Same day | 3–5 days |
| 5–19 units | 3–6 days | 1–3 days | 1–2 days | Same or next day | 5–8 days |
| 20 (one trailer) | 5–8 days | 2–4 days | 2–3 days | 1–2 days | 7–10 days |
| 21–60 | 1–2 weeks | 4–8 days | 3–6 days | 2–4 days | 2–3 weeks |
| 61–200 | 2–4 weeks | 1–2 weeks | 1–2 weeks | 4–8 days | 4–6 weeks |
| Over 200 or scheduled programme | By schedule | By schedule | By schedule | By schedule | By schedule |
Grade A food is slower than everything else because Route 3 runs at 55 units a day against 90 on the other routes, and because the paperwork is checked twice. In March to May, add roughly a week to Grade B and C — that is the agricultural pull, and it is the most predictable thing in this market.
Price, quantity and when to buy.
What is the most expensive mistake buyers make?
Specific gravity, by a wide margin, and it is never the container that fails. A 275-gallon tote of 50% caustic soda grosses 3,637 lb rather than 2,420. What fails is a forklift, a racking beam or a warehouse floor rated for the water figure.
Second place is buying Grade A for a job Grade C does. Third is ordering twenty-two units. All three cost more than the containers did.
Can I rent instead of buying?
We do not rent, and the arithmetic is why: a reclaimed tote costs a fraction of a new one and holds residual take-back value at end of life, so for almost every use case buying and selling back beats renting.
Where people genuinely want rental, what they usually want is a scheduled programme — units delivered when needed, collected when finished, credited on return. That we do, and it behaves like rental on your cash flow without the premium.
Why is one supplier's Grade A cheaper than another's?
Because 'Grade A' is not a standard. It is whatever each supplier means by it, and the only way to compare two of them is to ask what would disqualify a unit from that grade and what records come with it.
A washed unit with one documented food cargo, a logged Route 3 wash, a new gasket and a leak test with numbers on it is a different object from a rinsed unit that looked clean. Both get called Grade A. One of them costs forty percent more and is worth it; the other is a gamble priced like a certainty.
Is it cheaper to buy twenty or to buy five, four times?
Twenty, nearly always, and the reason is freight rather than any volume discount on the containers. Twenty units fill the floor of a 53-foot van, so the freight per unit is at its lowest point on the whole curve.
The cliff is just past it: twenty-two units pays for two trailers to move two containers. If your number is anywhere near a trailer boundary, tell us it is flexible and we will tell you which way to move it.
Do you ever tell people to buy a cheaper grade?
Constantly, and it is the most reliable sales tactic we have. Roughly half the enquiries that ask for food-grade are for site water, dust suppression, ballast or fabrication, where Grade C does the same job for about a third of the price and lasts exactly as long under that treatment.
The money we lose on the first order we get back on the next four, and it means that when we do say you need rebottled, you can believe us.
What does take-back actually pay?
It depends on condition band and on what the cargo was, and we quote it per unit rather than as one number for the lot — good units, utility units and reclaim units priced separately so you can see what you are being paid for.
We pay for units that will fail every test, because a cage is 55 lb of steel at 92% recovery and a bottle is 42 lb of HDPE at 68%. Buying that material from you is cheaper for us than buying it on the open market, which is the whole economic argument for a take-back programme existing.
Why are containers and freight on separate lines?
Because a single delivered number hides which of a dozen variables you are paying for, and makes comparing two quotes impossible. Grade, wash route, hardware, pallet base, plate status, lane, season and quantity all move independently.
It also means that when you come back in six months, we can tell you whether the price moved because resin moved or because diesel moved. If a quote you are comparing does not split them, ask — the answer tells you something either way.
One tote or five drums?
A 275-gallon tote holds the same as five 55-gallon drums. They are not interchangeable, and the deciding factor is almost never price.
The tote wins on
- Handling: one forklift move instead of five, one connection instead of five
- Floor space: 13.3 sq ft against roughly 20 for five drums on a pallet
- Dispensing: a 2-inch valve at the bottom beats pumping out of a bung
- Cost per gallon of container, typically by a wide margin
- Record keeping: one cage ID and one wash record instead of five of each
- Freight: 20 totes a trailer is 5,500 gallons; 80 drums is 4,400
Drums win on
- Splitting a batch across sites, days or production lines
- Weight per unit — one person with a drum dolly, no forklift
- Dedicating a container per cargo without dedicating a tote
- Aggressive cargo above SG 1.6, where lined steel drums are the practical answer
- Small-volume cargo where a part-full tote means a year of headspace and oxidation
- Sites with no forklift, no dock and no level bearing ground
Symptom, cause, what to do about it.
| Symptom | Most likely cause | Check first | Fix |
|---|---|---|---|
| Weeping at the valve when closed | Seat compression set from long open storage | Close fully, wipe dry, watch 10 min | Replace the valve; store closed in future |
| Drip from under the valve body | Flange gasket, not the valve | Feel behind the valve for wet | Pull the valve, new flange gasket |
| Cargo odour in a clean tote | Original gasket retained, or cap gasket | Smell the gasket itself, off the unit | New gasket; re-rinse; air with the cap off |
| Bottle bulging at mid-wall | Overfill, heat, or off-gassing cargo | Cargo SDS for gas generation; ambient temp | Vented cap at point of use; reduce fill to 85% |
| Condensate on top of the cargo | Vented cap left on in storage | Which cap is fitted | Solid cap for storage; vent only when dispensing |
| Crack at the lower corner | Water-based cargo froze at full fill | Fill level history | Unit is finished — we will take it back for reclaim |
| White cloudy patch at the sump | Stress whitening from forklift impact | Raking light for branching cracks | Monitor; no crazing means serviceable, Grade C |
| Fine branching cracks | Crazing, from chemical stress or UV | Any raking light at a shallow angle | Retire the bottle; the cage and base are reusable |
| Flow stops mid-discharge | Vacuum lock — no air in | Crack the top cap and listen | Vent while dispensing, always |
| Slow flow on a cold morning | Cargo viscosity, not a blockage | Cargo temperature against its SDS | Warm the product; never heat the bottle directly |
| Adapter binds after two turns | Wrong buttress standard | Compare S60×6 / S70×6 / S75×6 | Correct adapter or a proper reducer; never force |
| Cage node cracked | Impact, or a stacked load over rating | Count cracked nodes; check plate stack rating | Do not stack; return for cage swap |
| Tote rocks on the forks | Base weld failed at one corner | Lift 2 in and look at all four welds | Take out of service immediately — transplant job |
| Rust bleeding through the zinc | Galvanising breached, usually at a weld | Wire-brush a test patch | Cosmetic for utility use; fails food-grade intake |
| Label illegible after a season | Direct-print on HDPE in UV | Whether the UN plate is also fading | Stencil and clear-coat, or stainless tag |
The regulatory picture, in plain language.
This is a summary of how the rules work in practice, written so that you know which questions to take to your own compliance team. It is not legal advice and we are not your compliance team.
Two separate questions
First: is your cargo regulated for transport? If it has a UN number and a hazard class, the container needs to be a marked, in-date, design-approved packaging, and almost everything else follows from that. Second: is your cargo regulated for storage or use? That is a different body of rules — fire code, secondary containment, state environmental regulation — and a perfectly compliant container can still be in the wrong place on your site.
If the cargo is regulated for transport
The container needs a legible UN plate whose design category, packing group, maximum gross mass and test pressure all suit the cargo, and whose periodic test dates are in date: leak test every 2.5 years, full inspection and leak test every 5 years. A 31HA1 marked Y will not carry a Packing Group I cargo. A 31HA2 cannot be pressure-filled. Those limits are properties of the design type, not of how clean the unit is.
If the cargo is not regulated
Most of what moves in reclaimed totes — water, glycols, fertilisers, food products, utility liquids — is not regulated for transport, and the UN plate stops being a legal document and becomes a quality signal. This is why units with faded plates are good value: the container is sound, it has simply lost its licence for a job you were not asking it to do.
Who is responsible for what
The filler is responsible for the condition of the packaging at the moment of filling. That is the sentence worth internalising, because it means a supplier's wash record and leak test are inputs to your own decision, not a transfer of liability. Your incoming inspection matters, and the twelve-minute check elsewhere on this page exists for that reason.
What we will put in writing
The prior cargo and its filler. The wash route with every logged parameter. The leak test with its actual numbers. The UN plate photograph and the periodic dates. The gasket and hardware specification. And a signed statement of what we are not certified for, which is the half of a vendor pack most suppliers omit.
What we will not do
Tell you that a reclaimed container is compliant for your cargo. We do not know your cargo, your mode of transport, your jurisdiction or your customer's audit. We will give you every fact we hold about the container, promptly and in writing, and your own people make the call.
The six weekly lanes, and what riding one costs you.
| Lane | Runs | Transit | Single unit on the lane | Single unit on LTL |
|---|---|---|---|---|
| Detroit metro and Ann Arbor | Daily | Same day | Lowest — folded into the route | Not worth quoting |
| Toledo – Findlay – Columbus | Tue, Fri | 1 day | Low | 3–4× the lane rate |
| Grand Rapids – Holland – Muskegon | Wed | 1 day | Low | 3× the lane rate |
| Flint – Saginaw – Bay City | Thu | Same day | Low | 3× the lane rate |
| Chicago – Gary – Milwaukee | Mon, Thu | 1–2 days | Moderate | 2–3× the lane rate |
| Cleveland – Akron – Youngstown | Tue | 1 day | Moderate | 2–3× the lane rate |
| Indianapolis – Fort Wayne | Alternate Wed | 1–2 days | Moderate | 2× the lane rate |
| Everywhere else in the lower 48 | By carrier | 2–6 days | n/a | Quoted per shipment |
Lane day beats distance, every time. A single tote to Toledo on a Tuesday costs a fraction of the same tote to Toledo on a Wednesday, because on Tuesday it rides a truck that was already going. Always ask which day we run your lane before you fix a delivery date.
The fourteen fields that make a quote unambiguous.
Send us these and the quote comes back the same day, correct. Leave half of them out and we start with questions, which costs you a day.
- Cargo, by product name — and the SDS if it is anything unusual
- Specific gravity, or let us look it up, but somebody must
- End use: storage, transport, dispensing, fabrication, standby
- Quantity, and whether it is flexible — this is where trailer arithmetic saves you money
- Size: 275, 330 or 350 gallons, or tell us the volume and let us pick
- Grade, or better, let us recommend one from the cargo and end use
- Gasket requirement, if your cargo has one — EPDM, Viton or PTFE
- Valve and cap: standard, new, vented or specified
- Pallet base: steel, composite or any — and whether it is leaving the country
- Whether the UN plate must be legible and in date
- Delivery zip code, and whether you have a dock or need a lift gate
- Delivery window, and whether it is hard or indicative
- Documentation you need, and the format your auditor wants it in
- Whether you have old units to go back on the same visit
Ten questions that tell you what a supplier actually is.
Ask these of us too. A supplier who answers all ten without hesitation is running a real process; one who cannot answer three of them is reselling whatever came in on the last truck.
- What was in this specific unit, and who filled it? Hesitation here is the only red flag that matters.
- What would disqualify this unit from the grade you just sold me? No published disqualifiers means no grading system.
- Can I see photographs of the actual units before I pay, with the cage stamp visible?
- What did the third rinse read, and what did your supply water read that morning?
- Is the gasket new? If not, why am I paying for a clean container with the old cargo's elastomer in it?
- What method, pressure and hold time was the leak test, and what decay did it measure?
- Are the periodic test dates on the plate in date, and will you photograph the plate?
- Are containers and freight quoted as separate lines?
- Will you put in writing what you are not certified for?
- Will you take these back at end of life, and will you pay for them?
Freight, delivery and collection.
Why don't you have a telephone number?
Deliberately. Everything in writing means every grade claim, wash parameter, test result and freight quote is reviewable later — by you as much as by us — and nothing depends on what somebody remembers from a call.
In practice it is also faster. The reply to an emailed enquiry names the actual units with photographs and bay numbers, which is not something anyone can do while you hold the line.
What is the cheapest way to get one tote?
Ride a lane. We run six scheduled weekly routes out of Livonia, and a single unit folded into a truck that was already going costs a fraction of an LTL shipment of the same unit on a different day.
Ask which day we run your lane before you fix a delivery date. Lane day beats distance every time: a tote to Toledo on a Tuesday is cheaper than a tote to Toledo on a Wednesday by a margin that often exceeds the price difference between two grades.
Can you deliver without a dock?
Yes, but it has to be arranged at quote stage. A 53-foot van cannot put a tote on the ground by itself — that needs a lift gate, our own truck, or a forklift at your end rated for the real gross weight.
This is the most common reason a loaded truck leaves a site without unloading, and it is entirely preventable with one line in an email.
How many containers fit in a trailer, really?
Twenty filled 275s or 330s on the floor of a 53-foot van. Forty empties double-stacked. Eighteen filled in a 48-foot, ten in a 26-foot box truck, twenty-two in a 40-foot ocean container.
The number worth remembering is twenty, because it is the cliff. Twenty-two units pays for two trailers to move two containers, and we load-plan every multi-unit quote specifically to catch that before you commit.
Do you ship outside the Midwest?
Across the lower 48, by carrier, in two to six days depending on distance and lane density. Outside the six weekly lanes we quote per shipment because the freight stops being a rounding error and starts being a real part of the delivered cost.
For anything over twenty units the lane advantage matters much less, since you are paying for a dedicated trailer either way. Long-distance orders are usually full-trailer orders for exactly that reason.
Can you collect old units at the same time as delivering new ones?
Yes, and it is the best version of a take-back because the truck is already at your dock. Tell us at quote stage how many units are going back and roughly what condition they are in.
Our own fleet runs at 41% backhaul utilisation, which is what makes this work economically. A delivery that returns loaded is the cheapest collection either of us will ever get.
What happens if units arrive damaged?
Photograph the load in the trailer before anything moves, note the damage on the paperwork before signing, and email us with the cage stamp visible in the photograph. Units that are not as described come back on our freight, not yours.
That first photograph from the trailer door settles almost every freight dispute, which is why it is the first line of our receiving procedure.
Delivery readiness, so nothing goes back on the trailer.
Every item here has, at least once, sent a loaded truck away from a site without unloading. That costs both of us money and it is entirely preventable with an email.
- Somewhere level and bearing to put them — a full 275 is 2,420 lb on 13 sq ft
- A forklift rated for the real gross weight, not the water weight, if you are taking filled units
- Pallet jack access if the base is two-way only, which we will have told you
- Someone on site during the delivery window who can sign and who knows what was ordered
- A dock, or a lift gate requested at quote stage — a 53-foot van cannot put a tote on the ground
- Trailer access confirmed: turning radius, overhead clearance, gate width, weight limit on the approach
- Your own receiving check planned, with the despatch photographs printed or on a phone
- Secondary containment ready if your cargo or jurisdiction requires it
- Storage decided: indoors, or black and painted units if they are living outside
- The old units gathered in one place if we are collecting on the same visit
Rinse verification: the numbers behind a wash record.
| Measurement | Method | Pass tolerance | What it actually proves |
|---|---|---|---|
| Third-rinse conductivity | Inline probe, µS/cm | Within 10% of supply water | No dissolved residue carrying over |
| Supply water baseline | Measured each shift | Logged, not assumed | The comparison has a real datum |
| pH of final rinse | Probe | 6.5 – 8.0 | Caustic or acid fully flushed |
| Visual, 360° internal scope | Borescope on a mast | No film, no shadow, no deposit | Nothing clinging above the heel line |
| Odour, cap off, ambient | Two operators independently | Neither detects cargo | The check a buyer will make themselves |
| Wash temperature | Bay thermocouple, logged | Route 2 and 3: 140–160 °F | The chemistry ran where it works |
| Dwell time | Cycle timer, logged | Per route specification | Not a quick splash through |
| Rinse count | Counted charges, logged | Route 3: three full potable | Dilution did the work, not optimism |
| Drain-down | Inverted dwell | Under 100 ml retained | No pooled water to go stale in storage |
| Leak test after wash | Pneumatic pressure decay | Under 1 kPa in 10 min | The wash did not find a weakness |
Conductivity against the day's supply water is the measurement that matters, and it is the one most wash records leave out. A number with no baseline is decoration. Ask any supplier what their third rinse read and what the tap read that morning.
When to retire a container, and what happens to it then.
| Trigger | Severity | Reusable parts | Material route | Take-back value |
|---|---|---|---|---|
| Crazing anywhere on the bottle | Absolute | Cage, base, hardware | HDPE flake, 68% recovery | Partial — cage and base credited |
| Wall loss over 15% of nominal | Absolute | Cage, base, hardware | HDPE flake | Partial |
| Failed leak test after repair | Absolute | Cage, base | HDPE flake | Partial |
| Heat or fire exposure | Absolute, no exceptions | Nothing — all refused | Energy recovery | None |
| Excluded prior cargo | Absolute | Nothing | Licensed disposal | None, and we will say why |
| Persistent bulge over 6 mm | High | Cage, base, hardware | HDPE flake | Partial |
| Cracked weld nodes, three or more | High | Bottle, base | Baled steel, 92% recovery | Partial — bottle credited |
| Base weld failure | High | Bottle, cage | Baled steel | Partial |
| Odour that will not clear | Medium | Cage, base, hardware | HDPE flake | Partial |
| Illegible UN plate | Medium — regulated service only | Everything | Stays in non-regulated service | Full |
| Cosmetic staining | None | Everything | Back to service as Grade C | Full |
| UV chalking, surface only | None for utility use | Everything | Outdoor service as Grade C | Full |
Our standing offer is the same for all of it: when you are finished with a container, we collect and pay, including for units we will only break for material. That is cheaper for us than buying the same steel and resin on the open market, which is the whole argument for a take-back programme existing at all.
From enquiry to units on your dock, in seven steps.
No telephone lines, deliberately. Everything in writing means everything is reviewable later, by you as well as by us.
1 — You tell us the cargo and the end use
Not the grade. The cargo and what you are doing with it. Half the quotes we re-cut are because somebody asked for food-grade to hold site water, and the other half are because somebody asked for Grade B to hold a food product.
2 — We name a grade and say why
With the published disqualifiers attached, so you can see what would drop the unit out of that grade. If a cheaper grade does your job, we say so in the same email — it is a better business than selling you the expensive one once.
3 — Photographs of the actual units
Four per unit plus the cage stamp, tagged to a bay number, before you pay anything. Standard, not a concession, and not a stock image of a different tote.
4 — Containers and freight quoted separately
Two lines, always. A single delivered number hides which of a dozen variables you are paying for, and makes comparing two suppliers impossible.
5 — Load plan against trailer capacity
Twenty on the floor of a 53-foot van, forty double-stacked empty. If your number sits just over a trailer boundary we will tell you which way to move it before you commit.
6 — Despatch with the full record
Prior-contents sheet, wash record with logged parameters, leak test with actual numbers, UN plate photograph, component list, passport ID. One email, with the containers.
7 — Take-back, whenever that is
Months or years later, email the cage IDs. We collect and we pay, including for units that will only be broken for material. The record is still on file for seven years.
Washing, testing and verification.
What is the difference between rinsed and washed?
Route 1 is a rinse: one or two drained charges at ambient to 100 °F, verified visually. It produces Grade B and it is appropriate for a great deal of industrial and agricultural work.
Route 2 is a hot caustic wash: 140 to 160 °F, dosed alkaline detergent, three cascade charges, verified by conductivity and borescope. It produces Grade A washed. The gap between them is not a detail — it is the difference between a container that looks clean and one with a measured number behind it.
How can three rinses use only 11.5 gallons of fresh water?
Because the rinses cascade. The third rinse on one unit becomes the second rinse on the next and the first on the one after, so fresh water enters at the clean end and leaves at the dirty end. Eighty-six percent of bay water is recirculated.
It also means the direction of flow matters more than the volume, which is why the measurement we care about is third-rinse conductivity against the day's measured supply water rather than gallons used.
Can you get a cargo odour out completely?
Usually, and when we cannot the unit drops a grade and we say so rather than hoping you do not notice. Two operators check independently with the cap off at ambient temperature, because that is the check you will make yourself when it arrives.
The commonest cause of a lingering smell in an otherwise clean container is the gasket, not the bottle — the elastomer holds the prior cargo and no amount of rinsing the bottle addresses it. We fit a new gasket on every Grade A and B unit for exactly this reason.
What is ghosting, and does it matter?
A faint permanent shadow of a prior cargo visible through the bottle wall — most often from ferric chloride, a dye, or a strongly coloured fertiliser. It is cosmetic. The container holds and dispenses exactly as well as an unstained one.
It still costs a grade, because it means the prior cargo interacted with the polymer surface and because buyers reject it on sight. If you genuinely do not care how the tote looks, ghosted stock is some of the best value in the yard.
What happens to your wash water?
Eighty-six percent recirculates in the bay. The remainder goes to the sewer under an industrial wastewater discharge permit, whose number and latest sampling summary are in our vendor pack, and the sludge fraction is handled as a waste stream and appears in the residual line of our disposition table.
This is also why we will not advise you to pressure-wash a tote on your yard and let it run to a storm drain. That water is an effluent carrying your prior cargo, and in most jurisdictions it is a reportable discharge.
Why can't I buy my way onto the potable wash route?
Because the route is assigned at inspection by prior cargo, not at the sales desk by price. A unit that held an industrial product does not become a food container by going through Route 3 — the prior cargo is part of what Grade A food means.
If you need a food container and the available stock has industrial history, the answer is rebottling: a new bottle in an inspected cage. That is a real solution to the problem rather than a more expensive wash on the wrong unit.
Do you wash to a customer's own procedure?
Yes — Route 4. You send the written SOP, we run it and log every parameter it names: temperature, dwell, chemistry and dose, rinse count, verification method, operator, timestamps, all against the cage ID.
This is usually the cleanest way to satisfy an auditor, because the record is in your own format and names your own steps rather than asking somebody to accept ours by analogy.
Using the container, answered at length.
Is a tote safe for diesel or heating oil?
The container handles it: HDPE is good with diesel and a Viton gasket is correct — never EPDM, which swells in hydrocarbons. The constraint is almost never the tote.
It is your local fire code, insurer and state environmental rules, which often restrict storing fuel in a non-metallic container, require secondary containment, or cap the volume on site. Check before you buy, because the container will arrive compliant and the installation may not be.
Can I use a tote for compost tea or digestate?
Yes, and Grade B rinsed is the right stock for it. The one rule is venting: biological activity generates gas, and a sealed cap on a fermenting cargo will bulge the bottle and eventually deform it permanently.
Fit a vented cap or a breather valve at the point of use, keep the unit out of direct sun to limit the temperature swing, and expect to wash it out between batches rather than at end of season.
What size tote for livestock water?
A 275 on a level bearing pad, Grade B rinsed with a documented prior cargo, black or painted rather than translucent. Translucent bottles grow algae in one season in the open.
Our framed trough build is the better answer if animals have direct access: a half-height open trough, 120 gallons, with the cage left intact as the frame. Full totes should never be where livestock can rub against them — 2,420 lb on four square feet does not need much persuasion to tip.
Can I heat the contents of a tote?
Gently and indirectly, never with a direct heat source on the wall. A blanket rated for IBC use, or a warm room, is fine. A torpedo heater pointed at the bottle, a flame, or any local hot spot is not.
Keep the cargo below 100 °F for normal service. Above that the bottle softens, creep accelerates and the stacking rating halves; above 120 °F do not stack at all. Heat-affected HDPE never recovers its original wall strength, and the failure comes later with no visible warning.
How do I get the last of the cargo out?
Tip the unit forward slightly so the sump is the low point, and vent the top cap while you drain — most 'the valve is blocked' calls are a vacuum lock, not a blockage. Crack the cap and listen for air.
Expect to leave under a gallon as heel in a standard sump. If recovering that last gallon matters to your economics, ask about units with a dedicated discharge geometry rather than fighting a standard sump.
Can I cut a tote up myself?
People do, for planters and troughs, and it is straightforward with a jigsaw in the plastic and an angle grinder on the cage. Two warnings, both serious.
First, know what was in it: cutting into a bottle that held a solvent is an ignition risk, and never put your head or arm inside an intact container, which is a confined space that has killed people. Second, cut edges on HDPE are sharp and the cage tubes spring when relieved. Our fabricators build sixteen standard designs from Grade C and D stock, finished and deburred, if you would rather not.
What can I do with a tote that failed?
A bottle that cannot be trusted with a regulated cargo can hold rainwater for another fifteen years. Harvesting, planters, troughs, compost tumblers, ballast, erosion control, aquaponics sumps, dust suppression skids — sixteen standard builds, all from donor stock that failed container service.
And if you do not want it, we will collect it and pay for it. A failed unit is still 55 lb of steel at 92% recovery and 42 lb of HDPE at 68%.
How the container in your yard came to be shaped like that.
The modern caged IBC is a surprisingly young object, and almost every feature of it is the fossil of a specific problem.
Drums and nothing between
Liquids moved in 55-gallon drums or in bulk tankers. Anything in between meant handling dozens of drums, which is why the intermediate category was invented at all.
The first rigid composites
A blow-moulded plastic bottle inside a steel frame, sized to a pallet footprint so a forklift could handle it. The idea has not changed since.
The pallet footprint settles
40 × 48 inches in North America, 1,200 × 1,000 mm in Europe. Every trailer count on this site descends from that choice.
UN performance testing
Packagings began to be approved by design type and performance test rather than by prescription, which is where the 31HA1 marking family comes from.
Periodic testing arrives
The 2.5-year leak test and 5-year inspection cycle formalised, creating the date-stamped plate that decides whether a used unit can still carry a regulated cargo.
Reconditioning becomes a trade
Enough units in circulation, and enough value in a steel cage that outlasts three bottles, for washing and rebottling to be businesses rather than favours.
One bay and a used pressure washer
Re:IBCtote starts in a rented bay in metro Detroit, washing totes for local chemical blenders who could not get a straight answer about prior contents.
Grading gets published
We write down the disqualifiers rather than keeping them in an inspector's head, because the arguments about Grade B were taking more time than the washing.
The passport
Every unit gets a record keyed to its cage ID: intake, wash parameters, test results, grade, operator, dates. Seven-year retention, reissuable years later.
38,210 containers
Our largest year: 94.2% diverted, 4.4% residual published rather than rounded away, 4,281 tonnes of CO₂e avoided on factors we publish in full.
The same containers, different weather.
“Nobody has ever called us about a container failing. They call about a forklift, a rack or a floor, and it is always the same arithmetic: they multiplied gallons by 8.34 and the cargo was not water.”
Send us the cargo, not the grade.
Tell us what is going in the container and what you are doing with it, and we will name the grade, say what would disqualify a unit from it, and tell you if something cheaper does the job. That last part is why people come back.
