The rule we never bend

Food grade is a history, not a cleaning result.

This is the guide we send most often, usually to somebody about to buy a very clean-looking container for a food application. It is clean. It is also permanently unsuitable, and the reason is chemistry rather than hygiene.

Short answer

An IBC tote is food grade only when all three hold: the bottle is FDA-compliant HDPE, the entire prior-contents history is edible commodities, and it has been washed to a documented procedure. Washing cannot upgrade an industrial container, because polyethylene absorbs organic compounds into the wall and desorbs them over months.

Conditions: 3, all required
Resin standard: 21 CFR 177.1520
Upgradeable: No
Alternative: Rebottled

Tell us the product and we'll say whether used food-grade stock is defensible, or whether you need a new bottle.

Why absorption is the whole story

High-density polyethylene is not an inert barrier. It is a semi-crystalline polymer with amorphous regions that behave, at a molecular level, rather like a very slow sponge for organic compounds. Surfactants, glycols, aromatic solvents, plasticisers and many agricultural actives partition into those regions during service — driven by concentration, temperature and time.

When the container is emptied and washed, the surface is cleaned. The material in the wall is not, and it now has a concentration gradient pointing the other way. Over the following months it desorbs slowly back into whatever the container holds next.

This is why a container can pass a visual inspection, pass a smell test, pass a swab, and still contaminate a product two fills later. It is also why the food-grade rule has to be historical rather than observational. You cannot test your way out of it in any practical way, so the industry — the honest part of it — uses provenance instead.

The three tests, in order of finality

Resin. The bottle must be moulded from HDPE compliant with FDA 21 CFR 177.1520. Name-brand bottles almost always are; bottles with recycled content or unmarked offshore resin may not be and cannot be assumed to be.
History. Every prior fill must have been an edible commodity. One non-edible fill disqualifies the container permanently. This is the test that actually removes inventory.
Wash. A documented, repeatable procedure appropriate to the residue, with the record retained. The cleaning guide sets out which cycle each residue class needs.

Three firm refusals

Where we will not sell used stock at all.

Infant nutrition

The consequence of being wrong is unacceptable and the regulatory burden is different in kind. We quote new, every time, and we will not be argued out of it.

Pharmaceutical intermediates

Validation requirements exceed what any used-container documentation can support. New, and usually stainless.

Regulated potable municipal supply

Water intended for human consumption under a public water system. The documentation burden on a public system does not justify the saving, and we say so even though it is the smaller sale.

Food-grade questions

Chemistry and documentation.

Food grade — FAQ

Can washing make an industrial IBC tote food grade?

No. Polyethylene is semi-permeable and swells slightly in contact with many organic compounds. Surfactants, solvents, glycols, plasticisers and agricultural chemicals migrate into the bottle wall during service and desorb slowly back out over subsequent months. A surface wash removes what is on the wall, not what is in it. This is the single most important fact in the used container trade and the one most often glossed over.

How long does desorption take?

It depends on the compound, the temperature and the wall thickness, but the relevant timescale is months to years rather than hours. That is precisely the problem: the container passes a visual and olfactory check today and contaminates a product three fills later. Which is why the rule is historical, not observational.

What about a tote that held something edible but unpleasant?

Strong prior flavours — vinegar, fish oil, garlic concentrate, hot sauce base — are still food grade by definition, but carry-over is a genuine quality risk for a delicate next product. We record the specific prior product precisely so you can make that call. For allergen-controlled or flavour-sensitive lines, the defensible answer is a rebottled container with a new bottle and no history at all.

Do food-grade totes need to be certified by a third party?

There is no third-party certification of individual used containers, and anyone offering you one should be asked who issued it and against what standard. What exists is documentation: the resin supplier's FDA compliance statement, our intake prior-contents log and our wash record. Those three documents together are what makes a food-grade claim defensible in an audit.

Vocabulary, in twelve lines

IBC: Intermediate bulk container — anything between a drum and a tanker, in practice 110–550 gallons on a forkliftable base.
Composite IBC: An HDPE bottle inside a welded steel cage on a pallet base. The 275 and 330 gallon workhorses.
Tare: Empty weight of the container: 125–135 lb for a 275, 140–155 lb for a 330.
Gross mass: Container plus contents. Most 275s are rated to 2,800 lb; exceed it and the bottle bulges rather than bursts.
Node: A welded intersection in the cage where load actually transfers. The correct place to inspect.
S60x6: The standard outlet thread: 60 mm OD, 6 mm pitch buttress. Hand tight only.
Prior contents: What the container last held, logged against the original label. The single most consequential fact about any used tote.
Rebottle: A new HDPE bottle fitted into an inspected existing cage — virgin interior, 38% less embodied carbon than new.
Food grade: FDA-compliant resin plus an edible-only prior history plus a documented wash. All three, together.
UN 31HA1: Marking for a composite IBC approved for liquids. Belongs to the assembly and carries a service life.
Regrind: Granulated recycled HDPE. Post-industrial IBC regrind goes to pipe, conduit, pallets — never food contact.
Avoided burden: Environmental cost that did not occur because a container was reused instead of manufactured. Not an offset.
