Which certifications a water or food-grade container needs, and what to request from a supplier.

A water or food-grade container is only as trustworthy as its paperwork. The material has to be right, and the evidence has to exist for the exact design you buy. This sets out what applies, what the documents actually prove, and what to ask for, so a food-grade claim rests on more than a clean finish.
Food contact starts, and often ends, with the material. AISI 304 stainless steel and food-grade HDPE are the safe bodies. Galvanized steel is not: the zinc coating that protects it from rust is not food-safe, and no document changes that. A painted or lined steel can is a fuel can, not a water can. Confirm the build is stainless or food-grade resin before you look at a single certificate, because the paperwork only certifies a material that was already correct.
Here is the part cheap suppliers skip. A stainless body can be flawless and the can still fail a food-grade claim, because the gasket, the cap liner, the spout and the tap are plastic and elastomer, and they touch the liquid too. Food-contact compliance covers every part the water meets, not just the metal. When you ask for evidence, ask for it on the closures and seals as well as the body. It is where a food-grade claim most often quietly falls apart.
Food-contact rules are national, not universal. The EU framework, the US FDA regime, the UK’s water approvals and Japan’s positive-list system, which now permits only listed substances, each ask for different evidence. A single “food-safe” claim means little across all of them at once. Tell your supplier the destination and the paperwork can be aimed at the rules that actually apply there, rather than at a general impression of safety.
If a supplier cannot produce these for the design in front of you, treat the food-grade claim as unproven.
Our stainless water and food-grade lines are AISI 304 across the wetted path, chosen so the metal itself is the barrier with no liner to fail. We supply the material and food-contact documentation against your order and destination market, and we will tell you plainly what we hold and what we do not before you commit. See the water and food-grade range.
