Food grade vs. industrial, explained
What the terms mean, what they do not mean, and who decides.

Food grade
IBC totes
Food grade is a provenance claim, not a cleaning claim. It means we know what was in the tote, that it was edible, and that we can put that in writing. No amount of scrubbing turns an industrial tote into a food one.

Quantity and delivery ZIP are what move the price. Tell us those and the grade you think you need, and we will confirm or talk you down to something cheaper.
The short answer
A food grade IBC tote is a single-trip container whose one and only prior content was an edible product — typically corn syrup, fruit juice concentrate, vinegar, molasses, food-grade glycerin or an edible oil. We supply them washed, sanitised, with a new gasket and valve, and with a written prior-contents declaration naming the product and the shipper. Anything without that paper trail is sold as industrial, whatever it looks like.
- Single-trip only: one previous fill, always edible, always documented
- Prior-contents declaration issued with every unit, naming product and origin
- Hot wash and food-grade sanitiser rinse as standard; steam on request
- New EPDM or silicone gasket, new valve, new lid — never reused on a food unit
The four questions an auditor will ask you
If you are buying food grade totes for a licensed facility, your supplier's marketing copy is not the thing that will be examined. These four questions are.
- What was in it before, specifically? Not "food product" — a name, a shipper and ideally a lot. We give you all three.
- How many times has it been filled? Food grade means once. A tote on its third fill is a reconditioned tote with an optimistic label.
- What was it washed with, and was the wash water potable? Ours is municipal potable feed, hot, with a rinse-free food-grade sanitiser at label concentration.
- What was replaced? Gaskets and valves are porous, absorbent and impossible to verify. On a food unit they are new, not cleaned.
Prior contents we accept — and the ones we refuse
| Prior content | Accepted as food grade | Notes |
|---|---|---|
| High-fructose corn syrup | Yes | The most common source. Washes clean, no odour carry. |
| Fruit juice concentrate | Yes | Watch for staining on dark berry concentrates — cosmetic only. |
| Vinegar / acetic acid, food | Yes | Confirm cage condition; acid mist attacks galvanising. |
| Molasses, honey, glucose | Yes | Hot wash mandatory; cold water will not shift it. |
| Food-grade glycerin | Yes | Excellent candidate; near-perfect release. |
| Edible oils | Case by case | Rancidity risk. We reject anything with detectable odour. |
| Ethanol / spirits | Case by case | Fine chemically; check your own regulatory position. |
| Soap, surfactant, detergent | No | Industrial only, regardless of how clean it looks. |
| Any agricultural chemical | Never | Permanently disqualified from food service. No exceptions. |
| Unknown or unlabelled | Never | Treated as chemical and graded C at best. |
Cleaning you can do, and cleaning you should not attempt
Most buyers want to re-sanitise on arrival, which is sensible. A 6-inch lid gives you enough access for a spray ball on a lance; it does not give you enough access for an arm, so mechanical scrubbing is out.
- Do: hot potable rinse, then a food-grade sanitiser at label dose, then a potable final rinse if the sanitiser requires it.
- Do: run the valve open during sanitising so the outlet and seat see the same chemistry as the bottle.
- Do not: use chlorine bleach above about 200 ppm. It attacks HDPE over time and it will pit a stainless valve stem.
- Do not: steam an unvented bottle. HDPE softens near 175 °F and a sealed tote under vacuum on cooldown will implode. Vent it.
- Do not: pressure-wash the interior through the lid with a turbo nozzle. You will score the wall and create biofilm anchorage.
?Common questions
Questions people actually ask
Can I use a food grade IBC tote for drinking water?
For emergency and non-potable household use, yes, with a proper sanitise first. For a permanent potable system, specify a purpose-built potable build: new bottle, NSF-listed valve, food-grade gasket and an opaque or shaded install so algae cannot grow. Sunlight through a translucent bottle plus stored water equals green water within weeks.
Do you provide a certificate?
We provide a prior-contents declaration on our letterhead with the product name, the shipper, the wash method and the lot number, signed by the yard supervisor. That is the document our food customers file. We do not issue third-party lab certificates as standard, though we can arrange swab testing at cost if your programme requires it.
Why is a food grade tote more expensive if it is used?
Because supply is the constraint, not condition. Single-trip edible-contents totes are a small slice of the used market and everyone wants them. You are paying for provenance and scarcity, plus the new valve, new gasket and hot wash that industrial units do not get.
Is the plastic itself food safe?
The HDPE bottle is manufactured to food-contact specification from the outset — nearly all IBC bottles are, regardless of what ends up inside them. The variable is never the resin; it is the history.
