Kitchenware that contacts food — plates, cookware, utensils, food storage containers — is regulated under food-contact material rules that are separate from general consumer product safety standards. The EU, UK and US each maintain their own migration-testing requirements, checking that materials do not leach substances into food under normal use conditions.
Material matters more than design here. Melamine, silicone, ceramic glazes and certain plastics each have their own test protocols and, in some cases, their own restricted-substance lists. A supplier switching material mid-production run — a common cost-saving move — can invalidate test reports obtained for the original material without anyone downstream noticing until a customs query.
Glazed ceramics and enamelware carry an additional lead-and-cadmium migration test in most markets, applied specifically because of historical contamination issues in decorative glazes. This is one of the more commonly missed tests on first-time ceramic kitchenware orders.
As with cosmetics and toys, the logistics side of this is straightforward once compliance is resolved — the discipline is confirming material and test documentation match the actual production run before the container is loaded, not assuming the factory's general quality certificate covers it.
