Three things, all
true at once, or
it isn’t food grade.
This is the page where a lot of the used-container industry gets uncomfortable, because 'food grade' is used as a description of appearance rather than a statement about evidence. Here is what the phrase should mean.
The short answer
A defensibly food-grade used IBC needs an FDA 21 CFR 177.1520 compliant HDPE bottle, a documented history where every prior content was edible, and a wash to a written standard with recorded parameters. Missing any one and the accurate description is 'clean'. Where allergen control matters, rebottle instead of washing — no wash certifies absence.

The three-part test
What has to be true
01
Compliant resin
The bottle must be HDPE meeting FDA 21 CFR 177.1520 for food-contact olefin polymers. Every composite IBC bottle is HDPE, but not every plastic vessel on the used market is — and the specification covers the resin, not the container.
02
Documented history
Every prior content known and edible. One undocumented gap and the unit leaves the food lane permanently. This has to be collected at intake, from the source, in writing — it cannot be reconstructed afterwards.
03
Recorded wash
A named standard with recorded parameters: temperature, detergent, sanitiser, date, operator. The record travels with the container and is retained. A wash without a record is not evidence of anything.
Risk
Ranked by how often it actually bites
Not in order of severity — in order of how frequently we see each one cause a real problem.
| Risk | How it happens | Control | Residual risk |
|---|---|---|---|
| Allergen carryover | A tote that held an allergen-containing product is washed and reused for allergen-free production | Rebottle and dedicate; never wash across an allergen boundary | Low if rebottled; unquantifiable if washed |
| Undocumented prior contents | Tote bought as 'food grade' with no history; turns out to have held something else | Buy only with a prior-contents tag from a documented intake lane | Eliminated by documentation |
| Flavour and odour transfer | Strongly flavoured prior product absorbed into the polymer wall | Dedicate by product family; rebottle when switching | Low with dedication |
| Inadequate wash | 'Cleaned' means a rinse; sugars and biofilm remain | Specify a named standard — W4 for food | Low with recorded parameters |
| Cross-contamination in storage | Chemical and food fleets stored together; wrong tote filled | Physical separation and colour-coded cage tags | Low with separation |
| Post-delivery contamination | Lid left open, valve uncapped, tote stored in the sun | Sealed lid and capped valve until fill; indoor or shaded storage | Entirely in your hands |
Chain of custody
How a food-lane tote should be handled
This is our process. It is also a reasonable specification to hold any supplier to.
- STEP 01
Declared at the gate
Prior contents declared in writing by the source before the unit enters the food lane. No declaration, no food lane — the unit goes to general stock and is sold as general stock.
- STEP 02
Physically isolated
Held separately from chemical stock. Not a different row — a different area, so a forklift driver in a hurry cannot make a mistake that matters.
- STEP 03
Washed to a recorded standard
Caustic clean-in-place at 160°F, potable rinse to verified neutral pH, food-safe sanitiser, forced air dry, sealed. Parameters recorded per unit.
- STEP 04
Tagged, recorded, retained
Prior-contents tag and wash record attached to the unit and to the bill of lading. We keep a copy for seven years, because audits happen later than deliveries.
What the regulations actually say
FDA 21 CFR 177.1520
This governs olefin polymers — including HDPE — used in food contact. It is a specification about the resin: composition, extractables limits and conditions of use. It says nothing about what a particular container held last Tuesday, which is why resin compliance alone does not make a used tote food grade.
FSMA preventive controls
The Food Safety Modernization Act requires you to identify hazards and implement preventive controls with documentation. For containers, that translates into knowing and recording their history rather than relying on a supplier's characterisation. A prior-contents tag and a wash record are exactly the sort of evidence that satisfies this; a verbal assurance is exactly the sort that does not.
What is not a food-grade certification
- A UN marking — that is a transport specification, unrelated to food contact
- A clean appearance — see every page on this site
- NSF/ANSI 61 — a manufacturer programme that does not carry to reconditioned units
- “Previously held food” without a written record of which food
Choosing between F-grade and rebottled
Documented F-grade is right for syrup, molasses, edible oil, concentrate, cold brew and liquid feed — applications where prior contents were similar and allergen boundaries are not being crossed.
Rebottled is right for allergen-controlled production, potable and emergency water, shelf-stable product with a long hold, and any situation where you need to remove the prior-contents question entirely rather than manage it.
The price difference is real but smaller than most people expect, and considerably smaller than the cost of the event it prevents.

Tell us what's going in it.
Syrup and molasses are straightforward. Allergen-controlled or shelf-stable production usually isn't. Describe the product and we'll recommend F-grade or rebottled, honestly.
