Nine things we commit to, written plainly enough to be held against us.

A pledge that cannot be checked is marketing. Each of these has a number, a date or a document attached, and we publish when we miss.

The pledge

Nine commitments.

Reuse before recycling, always

No container is ground for material while it can still safely hold a load. Grade D is a test result, not a sales decision — and Grade D stock goes past the fabrication bay before it goes to the grinder.

Every container ships with its history

Prior-contents sheet, wash record where applicable, and photographs of the actual units. No anonymous totes leave this yard.

We publish our landfill figure

Not our diversion figure — anyone can make that sound good. The residual percentage, by unit and by weight, in the annual impact report.

Fresh water under 13 gallons per unit washed

Measured at the meter, published annually. 2025: 11.5 gallons. If this number rises, it goes in the report with an explanation.

Free take-back collection from eight units

Anywhere on our six weekly lanes. No disposal invoice, ever, for a container that can be reused or recycled.

Honest grading, even when it costs us

A unit that fails one food-grade criterion drops to Grade A washed and is priced accordingly. We would rather lose the premium than the trust.

We will quote you the reclaimed alternative

Every new-container quote includes the closest reclaimed option and the carbon difference written out. You decide; we just refuse to hide the comparison.

No offsets in our claims

We do not buy offsets and we do not net them against our figures. Avoided emissions are reported as avoided emissions, separately from our own footprint.

Published methodology, published failures

Every factor behind every number on this site is on the methodology page. Every missed target is named in the impact report, with the reason.

“We stopped writing 'environmentally friendly' on anything in 2019. It means nothing. Now we write the gallons, the pounds and the percentage that still goes to landfill, and people trust us more, not less.”

Founder · Re:IBCtote, Livonia
Hold us to it

If we have broken one of these, tell us.

The pledge is reviewed every January and republished with the impact report. If you have bought from us and something on this list did not happen, the fastest way to fix it is to say so in the form on this page — it reaches the same desk as our quotes, and the founder reads the ones that mention the pledge.

We have rewritten two of these commitments since 2019 because the original wording was too vague to be checked. That is allowed. Quietly dropping one is not.

  • Reviewed and republished every January
  • Two commitments rewritten for being unverifiable
  • None dropped
  • Misses published with reasons, not excuses

Reference FAQ

Ecology questions, answered at length.

Can I get a certificate for my sustainability report?

Yes, with every take-back collection: unit count, weighed mass, the split between resale, recondition, upcycle and recycle, and estimated CO₂e avoided referenced to the published factor table.

It is a much better figure than 'we recycle our containers', and it survives the question of where the number came from.

Is reusing a container actually better, or is washing it worse?

Better, by roughly thirty to one. A new 275-gallon composite IBC carries about 112 kg CO₂e of embodied impact. A wash cycle costs 2.3 kg CO₂e and 11.5 gallons of fresh water.

Reuse does not reduce embodied carbon; it amortises it. One cage across seven service lives divides the manufacturing impact by seven instead of paying it again each time.

Why do you publish your landfill figure?

Because a diversion rate without a residual figure is a marketing number. Anybody can say they divert 94% of their material.

Our 4.4% is mostly used gaskets, labels, adhesive residue and wash sludge. Gaskets are the largest contributor by count, they are thermoset, mixed and contaminated, and we genuinely cannot find anyone to take them.

Do you buy carbon offsets?

No, and we do not net anything against anything. Avoided emissions are reported as avoided emissions, separately from our own footprint.

Our trucks burn diesel — six tractors averaging 6.4 mpg. Milk runs and backhaul matching cut the miles per container by about 41%, which is real, but the fuel is still fuel.

Can my old bottles be recycled back into new tote bottles?

Realistically no, and anybody claiming otherwise is being loose with language. Post-industrial container flake carries prior-cargo risk and is not food-contact approved, and tote bottles are a demanding moulding application that wants consistent virgin-grade resin.

Our flake becomes drainage pipe, pallets and agricultural tubing at 68% recovery. Cages and pallets go to a regional electric arc furnace at 92% recovery.

Are your figures third-party verified?

No. The factor table and boundary definition get an external desk review each January by an independent consultant who checks arithmetic and factor sourcing.

That is a desk review, not certified verification, and we describe it that way deliberately. The full methodology, including three stated limitations, is published.

Every unit, every order

What arrives with the containers.

None of this is optional or chargeable. It is the difference between a reclaimed container and an anonymous second-hand one.

  • A prior-contents sheet naming the product, the fill date and the company that filled it
  • Four photographs of the actual unit plus an image of the cage stamp
  • The grade assigned, and the published criteria that grade commits us to
  • A wash record where the unit went through Route 2, 3 or 4, with temperature, dwell, rinse count and final rinse conductivity
  • A leak test record for every Grade A and Grade B unit: method, pressure, hold time and measured decay
  • The UN plate photograph and periodic test dates where the unit is marked
  • A component list naming gasket material, valve type and cap type
  • The cage passport ID, so the whole service history can be reissued later
  • An allergen flag where a prior food cargo included dairy, egg or tree-nut oils
  • A standing take-back offer: when you are finished, we collect and pay
Operational FAQ

How the operation actually runs.

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.

Do you work with public buyers?

Regularly — municipalities, fire departments, school districts, county emergency management and state agencies.

Itemised quotes with freight on a separate line, W-9 and insurance certificates in one email, sealed bids where required, and we will hold stock against a purchase order that has not cleared yet if you tell us the situation.

Can you run a fleet programme for containers I own?

Yes, and it is a large part of what the bench does. Out full, back empty, washed, inspected, gasket replaced, leak tested, back on your fill line.

Priced per unit against a defined scope with a guaranteed turnaround, plus a quarterly fleet health report forecasting how many cages and bottles are approaching end of life. That report is the part customers say they value most.

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.

Primer

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.

1 — Gate and declaration

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.

Every build uses stock that failed container service, which is the point: a bottle that cannot be trusted to hold a regulated cargo can hold rainwater for another fifteen years. Two fabricators run this bench, so capacity is finite — book ahead of spring.

Deep FAQ · impact

Impact questions, answered with the arithmetic.

Can I use your numbers in my own reporting?

Yes, and the methodology document exists for that purpose: every factor, its published range, and which end we chose. Several customers put the disposition record for their own returned units into their annual reporting.

We will also tell you what we do not have: no third-party verified LCA, no certification scheme membership, and a solar installation that covers 31% of yard electricity rather than the number we hoped for, because phase two is sitting in a utility interconnection queue. That list is in the vendor pack too.

What is the single biggest impact in the whole chain?

Making the container in the first place. Everything else — washing, freight, our yard electricity, the fleet — is small against the cradle-to-gate impact of 42 lb of virgin HDPE and 86 lb of virgin steel.

Which means the highest-leverage decision in this entire industry is not which supplier you buy from. It is whether the container you are about to buy needs to be new, and for most cargo the honest answer is no.

Does freight cancel out the benefit?

Not remotely, at the distances involved. At 0.40 kg CO₂e per mile for a trailer carrying twenty units, a 500-mile delivery is about 10 kg CO₂e per container. Avoiding one new tote is in the region of 150 kg CO₂e.

It matters at the margins, which is why we run six scheduled lanes and chase backhaul utilisation — 41% of our return legs are loaded. But no plausible freight distance in the lower 48 makes reuse the worse option.

What happens to the parts you cannot reuse?

HDPE goes to flake at 68% recovery after label and residue loss. Steel is baled and mill-confirmed at 92%. Contaminated fractions go to energy recovery — 535 units' worth in 2025, 1.4% of intake.

The genuine residual is gaskets, labels, adhesive and wash sludge: 4.4% of intake by unit count, 61,428 lb by weight. We publish it rather than rounding it away, and the weight comes from the scale rather than from a unit count.

How do you calculate avoided emissions?

Mass times factor, with every factor published. A reused container avoids the cradle-to-gate impact of the new one it displaced: 42 lb of HDPE at 1.86 kg CO₂e per lb, 55 lb of steel at 0.86, 31 lb of steel pallet at the same, less the 2.3 kg CO₂e of the wash cycle and the freight at 0.40 kg CO₂e per mile.

Where a published range exists we use the end that makes our own numbers look worse — 1.86 against a range up to 2.4 for HDPE, for example. That systematically understates our impact, which is the direction we would rather be wrong in.

Why do you publish a landfill figure?

Because a diversion rate without a residual figure is a marketing number. Ours was 94.2% diverted and 4.4% to landfill in 2025 — gaskets, labels, adhesive and wash sludge, 61,428 lb of it, weighed on the yard scale.

If a supplier quotes you a diversion percentage and cannot immediately tell you what the residual was and what it consisted of, the percentage is not measured. It is estimated, and estimates in this industry drift upward.

Is reuse really better than recycling?

By a wide margin, for this product. Recycling a tote recovers 68% of the HDPE and 92% of the steel and then spends energy turning flake back into a product. Reusing it spends 2.3 kg CO₂e on a wash and keeps 100% of both materials doing the job they were made for.

That is why our disposition table reads 61.4% resold as containers and 18.9% reconditioned, with recycling at 7.2%. Recycling is what we do when reuse has genuinely been exhausted, not as a first resort with a better story attached.

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.

How it goes

Selling us your empties, in six steps.

We buy containers in any condition, including units that will fail every test. Material has value, and a collection that only takes the good ones leaves you with a disposal problem.

1 — Count and name the cargo

How many units, what size, and what was in them — product name and the company that filled them. The cargo decides the price and whether we can take them at all; the condition decides the rest.

2 — Photographs, rough is fine

A phone photograph of the stack and a couple of close-ups of the worst units. We are not grading from photographs, we are checking for the obvious disqualifiers before sending a truck.

3 — Written offer, per unit, by condition band

Not one number for the lot. Good units, utility units and reclaim units are priced separately, so you can see what you are being paid for rather than taking an average on trust.

4 — We schedule onto a lane

If you are on one of our six weekly routes, collection is usually inside the week and costs nothing. Further out we combine with a delivery going your way, which is what backhaul utilisation of 41% is for.

5 — Weighed and counted on arrival

Yard scale, against the manifest. Any discrepancy comes back to you with the scale ticket, in both directions — we have paid out more than was offered more than once.

6 — Payment, and a disposition record

Payment on agreed terms, plus a written record of where your units actually went: resold, rebottled, upcycled, recycled to material, or the residual fraction. Several customers use that record in their own reporting, which is why it exists in that format.

Decision

New container against reclaimed, without the sales pitch.

There are jobs where a new container is the right answer. We would rather say so than sell you the wrong thing and collect it back in a year.

Buy new when

  • The cargo is a regulated Packing Group I material
  • You need a specific design type, pressure rating or exotic liner nobody reclaims
  • Your customer's audit requires virgin packaging in writing
  • The product carries an allergen claim and rebottled will not satisfy the auditor
  • You need five hundred identical units with identical plate dates on one date
  • The container is part of a sealed, validated single-use process

Buy reclaimed when

  • The cargo is water, glycol, fertiliser, a utility liquid or an unregulated industrial product
  • A documented prior cargo and a published wash route satisfy your requirement
  • You want the same container at 30 to 60 percent of the new price
  • You want the impact figure, and the methodology behind it, in your own reporting
  • You need units this week rather than on a moulder's lead time
  • You want rebottled: a new HDPE bottle in an inspected cage, which is new where it touches the cargo
Field guide

Rainwater harvesting with reclaimed totes, done properly.

This is the most common non-industrial use of a reclaimed tote and the one where the mistakes are most consistent. The design brief is simple: get roof water in, keep light and insects out, and let the overflow leave in a controlled direction.

Choose the right donor

Grade B or C, and black or painted rather than translucent. Light is the enemy: a translucent bottle in the open grows algae within one season and loses measurable wall thickness to UV within five. We paint or wrap every harvesting build for this reason. Never buy Grade A food stock for rainwater — you are paying three times the price for a wash route that the first leaf of autumn makes irrelevant.

Weight, which people underestimate

A full 275-gallon tote weighs about 2,420 lb. That is a small car on four square feet of footprint. It needs level, bearing ground — compacted gravel, pavers or a concrete pad — and it must not sit on soft soil that will subside on one corner and rack the cage. Never stack filled harvesting units. Never place one above anything you care about.

Inlet

Cut the 6-inch top port, fit a mesh basket strainer and a first-flush diverter. The diverter sends the first few gallons off the roof — the ones carrying the bird mess and the grit — away from the tank, and it is the difference between water you can irrigate with and a sump full of sludge. Keep the whole inlet path light-tight.

Overflow

The thing most builds get wrong. Every tank will overflow, and the only question is whether you chose where. Fit an overflow at least as large as the inlet, below the top of the tank, directed away from foundations. An unplanned overflow finds the top cap and runs down the cage into whatever the tank is standing on.

Outlet

The factory 2-inch valve with a camlock adapter and a GHT reducer handles a hose or a pump. Gravity gives you roughly 1.5 psi at the outlet for every three and a half feet of head, which is enough to fill a watering can and not enough for a sprinkler — so plan a pump if you want pressure.

Winter

Drain to below 85% before the first hard freeze, or empty entirely. Leave the valve open and the cap on. Ice in a full harvesting tote cracks the lower corner, and we see those units come back every March.

What the water is and is not

Roof runoff is non-potable. It is excellent for irrigation, washdown, dust suppression and toilet flushing where local rules allow, and it is not drinking water regardless of how clean the tank was. Keep it dark, keep it moving, and use it within a season rather than storing it over summer.

Deep FAQ · process

Washing, water and effluent.

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.

How do I know the wash record belongs to the container I received?

The cage ID. Every record — intake, wash, leak test, grade, photographs, operator, dates — is keyed to the stamp on the cage you are holding, and the despatch photographs include a shot of that stamp.

Retention is seven years and reissue is a matter of emailing us the cage ID. People do this years later, usually because an auditor has asked a question about a container bought by somebody who has since left.

What does a leak test actually involve?

Pneumatic pressure decay on the complete assembly: pressurise to the design test pressure, hold, and measure the loss. Our pass criterion is under 1 kPa in ten minutes, and the record states method, pressure, hold time and measured decay.

A leak test record with no numbers on it is not a leak test record. That is the single most useful thing to check on any supplier's paperwork, including ours.

Is there anything a wash cannot fix?

Plenty. Crazing, wall loss, a persistent bulge, cracked weld nodes, a failed base weld, heat exposure, an illegible plate — none of those are cleanliness problems and no wash route touches them.

And some cargo we will not try: pesticides, pharmaceutical actives, PFAS formulations, isocyanates, polymerising oils, radiological material, anything fire-affected, and anything nobody will name in writing. Those are refused at the gate, because the downside of being wrong is a drained loop and a contaminated batch.

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.

Field guide

Rinsing a tote yourself: what works, what is theatre, and what is dangerous.

Sometimes you have a unit on site and a job to do. Here is what you can realistically achieve with a pressure washer and a hose, and where the line is.

First, the thing that is actually dangerous

Never put your head or an arm inside an IBC, and never let anyone else. It is a confined space. A tote that held a solvent, a fermenting product or anything that displaces oxygen can be lethal with no smell and no warning, and people die in containers this size every year. Everything below is done from outside the unit.

What you can do

A hot water rinse with a wand through the 6-inch port, three drained charges, will take a water-soluble cargo residue down to a level that is fine for irrigation, dust suppression, ballast or washdown. Drain fully between charges — dilution only works if the previous charge leaves. Invert or tip to drain the sump, because the heel is where everything concentrates.

What makes a real difference

Heat, agitation and a new gasket, in that order. Warm water does more than cold at any pressure. A spinning wand beats a static one. And replacing the gasket and cap costs a few dollars and removes the most common source of carried-over odour — the elastomer holds the prior cargo and no amount of rinsing the bottle addresses that.

What is theatre

One cold rinse and a sniff. Bleach into an unrinsed tote, which mostly produces a tote that smells of bleach and cargo. Detergent with no heat and no dwell time. And any process that does not include draining the sump, which is where the problem lives.

What you cannot do on site

Produce a food-grade container. Route 3 is three full potable charges at 140 to 160 °F with dosed food-safe chemistry, verified by third-rinse conductivity against measured supply water, a borescope and two independent odour checks. That is a bay, not a bucket. If the end use is food, potable water or anything with an audit behind it, buy rebottled or Grade A food — the premium is smaller than the risk.

And the legal bit

Your wash water is now an effluent carrying the prior cargo. Down a storm drain it is a reportable discharge in most jurisdictions. We hold an industrial wastewater discharge permit and publish the number in our vendor pack; a yard hose does not come with one.

Background

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.

1950s

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.

1960s

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.

1970s

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.

1980s

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.

1990s

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.

2000s

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.

2009

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.

2017

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.

2023

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.

2025

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.

Deep FAQ · commercial

What the take-back programme pays.

Do you charge for the documentation?

No, and we would rather you did not ask it as a question, because a supplier who charges for a wash record is telling you the record is a product rather than a byproduct of the process.

The prior-contents sheet, wash record, leak test, plate photograph, component list and passport ID come with every order. The vendor pack — W-9, insurance certificate, wash SOP, discharge permit, methodology, and the signed statement of what we are not certified for — arrives in one email, usually inside the hour.

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.

Procedure

Storing and stacking: the rules, and why each one exists.

Most storage damage we see on returned units comes from four or five decisions, all of which look harmless at the time.

Read the plate before you stack anything

The permissible superimposed load is marked on the UN plate. A zero means do not stack, even empty. Where a figure exists, it assumes a container at normal temperature on level ground with an evenly distributed load above it — not one in July sun, not one on a tilt, not one with a second unit landed on a corner.

Filled stacking

Two high, same footprint, same size, directly aligned cage on cage, on flat bearing ground, below 100 °F ambient. Above 100 °F derate by half; above 120 °F do not stack at all. Never stack a filled 275 on a filled 330, never stack across different footprints, and never stack onto a unit whose cage has cracked nodes or an out-of-square diagonal.

Empty stacking

Four high is routine for transport and two to three high is sensible for standing storage, which is how a 53-foot trailer takes forty empties against twenty filled. Empty does not mean weightless: an empty 275 is still 127 lb on top of whatever is under it.

Racking

An IBC in a rack is held by its base, and the rack needs to be rated for the real gross weight — which means net volume times the actual specific gravity of your cargo, plus tare. A 275 of 50% caustic is 3,637 lb, not 2,420. Racking failures in this trade are almost always a specific gravity arithmetic error rather than a rack defect.

Outdoors

Black or painted bottles only, if the unit is going to live outside. Translucent HDPE in the open loses roughly ten percent of its wall on the sun face in five Michigan years, with the shadow pattern of the cage printed into the plastic where the tubes shaded it. Keep units off bare soil, on gravel or pavers, where meltwater drains away from the base rather than freezing around it.

Secondary containment

Decided by your cargo and your jurisdiction, not by the container. If you need it, size it for the largest single container plus a margin, and remember that a spill pallet rated for a drum is not rated for an IBC.

The boring one that matters

Valve closed, solid cap on, dust cap fitted, in storage. Every time. A valve stored open takes a compression set in the seat and weeps when you finally close it, and that is the single most common post-delivery complaint in this trade.

Two more

The same containers, different weather.

A tote yard after rain with stacks of white and black totes and covered storage under a canopy.
After rain. Black UV-stabilised bottles in the near stack — the ones we recommend for anything living outdoors.
Totes racked under a steel canopy next to blue and white containers on wet concrete.
Racked storage under the canopy, sorted by configuration. A rack is rated for real gross weight, not for water weight.

“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.”

Still deciding?

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.
