Grade A Is Not Food Grade, and the Difference Costs Real Money
The most abused phrase in the used-container business, and the three things that have to be true before anyone should use it.

The short version
Food grade is a documentation claim, not an appearance. It needs an FDA-compliant bottle, a recorded history of edible prior contents, and a wash to a written standard. Missing any one of the three, the honest word is 'clean'.
Somewhere in the used-container trade, 'food grade' stopped describing a documented condition and started describing a container that looks nice. That drift is convenient for sellers and expensive for buyers, and it produces a specific, predictable failure: someone buys a bright, clean, entirely presentable container, puts syrup in it, and discovers during an audit that they cannot say what was in it before.
Three things, all true at once
A used IBC is defensibly food grade when all three of the following hold. Not two. Three.
An FDA-compliant bottle
The resin has to meet FDA 21 CFR 177.1520, which governs olefin polymers in food contact. Every composite IBC bottle we handle is HDPE and meets it. This is the easiest of the three to satisfy and, tellingly, the one sellers most often cite — because citing it sounds technical while committing to nothing about the specific container in front of you.
A documented history of edible prior contents
Every single thing the bottle has held must be known and edible, and it must be written down. One undocumented gap and the container is out of the food lane permanently. Critically, this information can only be collected at intake, from the source. It cannot be reconstructed afterwards, and it cannot be inferred from how the container looks.
A wash to a written standard, with a record
'Cleaned' spans a cold hose-down and a recirculating caustic clean-in-place at 160°F. Those two processes are separated by roughly two orders of magnitude in effectiveness. A wash without recorded parameters — standard, temperature, detergent, sanitiser, date, operator — is not evidence of anything, because there's no way to know afterwards which of those two it was.
What this actually costs
In both directions, and the errors are asymmetric.
| Mistake | How it happens | What it costs |
|---|---|---|
| Over-buying | Documented food-grade stock purchased for wash water, glycol or jobsite duty | Roughly double the price of Grade B, for zero benefit. Common, and merely wasteful. |
| Under-buying | A clean Grade A container treated as food grade | A failed audit, a rejected lot, or a contamination event. Rarer, and considerably more expensive. |
Most operations make the first mistake for years without noticing, because nothing goes wrong — it just quietly costs more than it needed to. The second mistake goes unnoticed until precisely the moment it matters.
The allergen problem nobody plans for
This is the part of the conversation we most often have to introduce ourselves, because customers rarely raise it.
Washing reduces residue. It does not certify absence. If your food safety plan depends on an allergen-free status, a reused bottle introduces a risk you cannot close with a cleaning process, no matter how good the cleaning process is. No honest reconditioner will give you an allergen-free guarantee on a bottle that has held something else, and you should be suspicious of one who does.
The answer there is rebottling — a new virgin bottle in a reconditioned cage — and dedicating the units. It costs more than washed food-grade stock and considerably less than the event it prevents.
What we can and can't give you
- We can give you a prior-contents tag collected at our own gate, from the source.
- We can give you a wash record with recorded parameters, retained for seven years.
- We can give you a virgin bottle, which removes the prior-contents question entirely.
- We cannot give you container-level NSF/ANSI 61 certification — that's a manufacturer programme and it does not carry over to reconditioned units.
- We cannot give you an allergen-free guarantee on a reused bottle. Nobody can.
That last pair is where a lot of sellers become vague. If your specification cites NSF 61, you need new containers, and any yard telling you otherwise is either confused or hoping you are.
How to buy this well
Ask three questions and the whole thing resolves: what was in it, what wash standard was applied, and can I see the record. A supplier with a food lane will answer all three specifically and without hesitation, because collecting those answers is the entire point of running a separate lane. A supplier without one will change the subject to how clean the container looks.
