Six questions that expose a bad container seller

1. What exactly was in these, and how do you know?

A real operation records prior contents at intake from labels, plates and shipper paperwork, and can tell you per lot rather than in general terms.

Good answer: the specific product, the shipper, and an offer to send the record. Bad answer: a category — food, or chemicals, or general industrial — with no source.

2. What do your grades mean?

Grade A, B and C are not standardised across the industry. Anyone using them should be able to state their own definitions in a sentence each.

Good answer: a description of what distinguishes each grade, ideally including that staining is graded as cosmetic rather than as contamination. Bad answer: used, which is not a grade.

3. Are they pressure tested, and at what?

This is the question that separates a wash from a reconditioning process. A container that has been cleaned but never tested may look perfect and leak on a truck.

Good answer: a specific test pressure and hold, with a record per unit. Bad answer: they are checked, or they are inspected.

4. What happens to the ones that fail?

This question is not about ethics, it is about diagnostics. A seller who knows exactly where rejects go has a process that sorts them. A seller who does not is probably not rejecting many.

Good answer: bottles to reclaim or rebottling, cages to repair, steel baled, with rough proportions. Bad answer: we do not really get failures.

5. How is food-grade stock kept separate?

Even if you are not buying food grade, this answer tells you how the yard thinks. Segregation is expensive and inconvenient, and a yard that does it properly does other things properly.

Good answer: a dedicated pad, dedicated handling equipment, separate wash shifts and prior-contents records held per unit. Bad answer: they are kept apart, or all our stock is clean.

6. What will you not sell me?

The most revealing question on the list, and the one nobody expects. Every real operation has a list of things it declines to do.

Ours: we will not sell a used industrial container for food or potable service whatever the customer insists, we will not recertify a container with an illegible plate, and we will not sell grade A stock for a job that grade C would do.

A seller with no such list will sell you anything, which sounds like flexibility right up until it is your problem.

Three answers that should end the conversation

1. 01"It is food grade because it is clean." Cleanliness is not a status. Documentation is.
2. 02"We can wash that out." Absorbed chemistry does not wash out of polyethylene, and a seller who says otherwise either does not know or is hoping you do not.
3. 03"All our containers are the same." No yard's stock is uniform. This means nobody is grading.

None of these questions require expertise to ask, and all of them are answerable in under a minute by anybody who actually processes containers. That asymmetry is the point.

Two more questions, for larger orders

The six above work for any purchase. If you are buying by the truckload or setting up a supply relationship, add these.

Seven: what is your reject rate, and what are the top three reasons? A yard that measures this can answer immediately with a breakdown. A yard that cannot is not grading systematically, whatever its price list says.

Eight: can I visit? Not because you need to, but because the answer tells you whether the operation is one that survives being looked at. Every reconditioner we respect says yes without hesitation.

What good answers sound like in practice

The asymmetry that makes this work

None of these questions require you to know anything about containers. All of them are answerable in under a minute by anybody who actually processes them, and none of them can be bluffed convincingly by somebody who does not.

That is the whole value of asking. You are not testing knowledge; you are testing whether a process exists.

One question to ask yourself

What is this container actually for? Half the buyers we talk to are specifying a grade higher than the job needs, usually because a previous supplier sold on appearance.

A good seller will ask you this before you ask them anything. If nobody has asked what is going in the container, nobody is helping you buy the right one.

What to do with the answers

The questions are not a pass or fail test. Plenty of legitimate sellers are brokers who do not process containers themselves, and there is nothing wrong with that provided you know it.

What you are establishing is which risks sit with you. A seller who processes and documents is carrying the risk that a container is not what they said. A seller who is passing stock through is not, and your inspection has to be correspondingly more thorough.

Price should reflect that. Undocumented stock from a middleman is worth less than documented stock from a processor, and if it is priced the same you are paying for a service you are not receiving.

One question for yourself

How much does it matter if this container is not what I was told? For jobsite water, very little — inspect on arrival and move on. For a food line or a hazmat shipment, enormously, and at that point buying on documentation rather than on price is not caution, it is the only defensible approach.
