Reading a certificate: what HACCP, ISO 22000, and FDA registration actually cover

A quote that arrives with a stack of certificates is reassuring, but only if you know what each one is actually checking. The three that come up most often for a food-grade salt shipment are HACCP, ISO 22000, and FDA facility registration — and they cover different things.

HACCP (Hazard Analysis Critical Control Point) is a process, not a product test. It means the supplier has identified the specific points in production where contamination risk is highest — crushing, drying, packing — and has controls at each one. It tells you the process is being watched, not that any single bag has been tested.

ISO 22000:2018 is the management-system layer above HACCP: it means the food safety controls aren't ad hoc but are documented, audited, and repeatable across every batch, not just the one a buyer happened to sample.

FDA food facility registration is narrower than either — it's a US regulatory requirement for any facility whose product enters the US food supply. It confirms the facility is on record with US authorities; it isn't itself a quality certification.

Halal certification, where required, is usually issued per shipment rather than held permanently — worth confirming with a supplier before assuming it's automatically included, since "available on request" and "included by default" are different commercial terms even when the paperwork looks similar.

The practical takeaway: ask what each certificate actually verifies, not just whether the supplier "has certifications." A documentation pack with the wrong three acronyms is not the same as one with the three that matter for your market.
