US buyers check FDA limits (2.0 ppm lead for hollowware under 1.1 litres) plus California Prop 65; EU buyers need Directive 84\/500\/EEC (4.0 mg\/L lead for hollowware) and, in Germany, LFGB. A test report covers a body, glaze and decoration combination, not a shape.<\/p>\n\n\n\n
If a container of ceramic mugs is rejected at a US port, or quietly dropped by a German retailer, the cause is rarely the clay. It is the glaze chemistry and the paperwork nobody specified. Ceramic mugs are food-contact articles, and the United States and the European Union police them with different limit values, different test methods and different documents. Buyers who treat “FDA approved” as a single box to tick end up paying for re-testing, re-glazing or a second production run. This guide sets out the limits each market actually enforces, what a test report does and does not cover, and how to check a factory before you commit to a 5,000-piece order.<\/p>\n\n
The United States regulates ceramic foodware through enforcement limits published by the Food and Drug Administration, expressed in parts per million of extracted lead and cadmium. The European Union works from Directive 84\/500\/EEC, which sets migration limits in milligrams per litre for hollowware and milligrams per square decimetre for flatware, sitting under framework Regulation (EC) No 1935\/2004 and good manufacturing practice Regulation (EC) No 2023\/2006. Because the units differ, a mug that passes an FDA test is not automatically compliant in the EU, and the reverse is also true. Add California Proposition 65 for US retail and Germany’s LFGB for EU retail and one SKU can need three separate reports. Decide which markets you are actually selling into before you approve samples, because the glaze chosen for the EU is usually the safer one to run across every market.<\/p>\n\n\n
FDA compliance for ceramicware is judged against Compliance Policy Guide 7117.07 for lead and 7117.06 for cadmium. The extraction limits are 3.0 ppm lead and 0.5 ppm cadmium for flatware, 2.0 ppm lead and 0.5 ppm cadmium for small hollowware under 1.1 litres, and 1.0 ppm lead and 0.25 ppm cadmium for large hollowware of 1.1 litres and above. A standard 11oz mug is small hollowware, so 2.0 ppm is the figure your buyer will quote back at you. The test is an acetic acid extraction, commonly run to ASTM C738, and the result follows the glaze and the decoration rather than the body clay. One point that surprises importers: the FDA does not certify factories and issues no certificates of its own. The limits are enforced at the border, so legal responsibility sits with the importer of record. If a supplier sends an “FDA certificate”, treat it as a lab report and read the item description before forwarding it to a retailer.<\/p>\n\n\n
Prop 65 is why a mug can be legal across the United States and still need a warning label in California. The law sets maximum allowable dose levels of 0.5 micrograms per day for lead and 4.1 micrograms per day for cadmium, and a business must either stay below those levels or provide a clear and reasonable warning. For foodware this is measured through migration testing, which in some categories makes it a stricter practical bar than the FDA figures. Large US retailers and marketplace sellers increasingly ask for a Prop 65 report rather than an FDA report, because the warning obligation follows the product onto the shelf. The failure mode is quiet: nothing gets seized, the goods simply cannot be listed without a warning, and few buyers will put a warning label on a premium mug. If you sell into US retail, budget for the Prop 65 test alongside the FDA test; they can use the same sample.<\/p>\n\n\n
Directive 84\/500\/EEC splits ceramic articles into three categories. Flatware such as plates and platters may not exceed 0.8 mg\/dm2 lead and 0.07 mg\/dm2 cadmium. Hollowware with a capacity below 3 litres, which covers mugs, cups and most bowls, is limited to 4.0 mg\/L lead and 0.3 mg\/L cadmium. Hollowware of 3 litres and above is limited to 1.5 mg\/L lead and 0.1 mg\/L cadmium. Those are migration limits measured on the finished, decorated article, so the decoration is part of the test, not an accessory to it. Under Regulation 1935\/2004 you also need a written declaration of compliance for the material, and the manufacturing step itself is covered by Regulation 2023\/2006. In practice an EU buyer wants the test report plus that declaration, and the report has to name the exact article and the glaze. Anything generic, such as a report naming only the factory, comes straight back.<\/p>\n\n\n
Germany adds a sensory requirement on top of the migration limits. LFGB, the national food and feed code, requires that a ceramic article not transfer odour or taste to food, so a laboratory smells and tastes an extract as well as analysing it. German retailers, discounters and their importers ask for an LFGB report more often than for a plain EU report, which is why it is the document we suggest most EU buyers keep on file: it satisfies the base directive and adds the sensory test German buyers want. REACH sits alongside this as the broader chemical framework for the EU. It restricts certain substances in consumer articles and requires communication about substances of very high concern above 0.1 percent by weight. For a normal ceramic mug the migration tests are the ones your buyer will read; REACH is what their legal team checks. If you want one document pair to open the widest range of EU accounts, LFGB plus the declaration of compliance is it.<\/p>\n\n\n
A ceramic test report is tied to a body, a glaze and a decoration method, not to a shape. Change the shape and the report stays valid; change the glaze, the colourant or the decal and it does not. This matters as soon as a range has several colours. If your six colourways use three different glazes, you need three reports, and if one colour is applied as an on-glaze decal while the rest are under-glaze, that colour needs its own test. Durability is the other gap. EU and US buyers both ask whether the article still complies after washing, and a dishwasher cycle test at high temperature is a different test from the initial migration test. The most expensive failure we see is a buyer who approved a plain sample, went to production, and let the factory switch glaze supplier mid-run to save a few percent. Those finished goods were never tested, and the rejection came at the retailer.<\/p>\n\n\n
Ask for the test report, then read four things on it: the laboratory name, the test date, the article description and the glaze or decal code. Reports from SGS, Bureau Veritas, Intertek or TUV carry weight with buyers; a factory’s internal report usually does not. Confirm the report covers the right category, because a flatware report will not satisfy a mug buyer. Then agree an expiry convention. We work to annual re-testing, plus an immediate re-test whenever the glaze supplier or the colourant changes. Ask for the declaration of compliance for the EU, and keep a named contact at the factory who can pull the certificate of analysis for a specific glaze batch. Finally, decide before production who pays for the tests and who owns the reports. Buyers who write this into the purchase order pay for one test round; buyers who leave it to the factory pay for a second production run. If you want your current specification checked against these limits, send us your glaze and decoration details<\/a>.<\/p>\n\n\n Every rejection story in this article started with a specification that was never written down. Put the market, the limit value, the glaze code and the report owner into the purchase order, and ceramic compliance stops being a gamble and becomes a line item. The factory that can name its glaze supplier and produce a current report on request is the one worth keeping.<\/p>\n\nCertification Is a Specification Problem<\/h2>\n\n\n\n
