Is Xtrema third-party tested?

Last reviewed July 2026.

Yes — and the results are published. Xtrema’s headline safety claims are backed by published third-party testing (SGS et al. (brand-commissioned, posted) + independent EPA-certified lab via Mamavation). That puts it in the verified tier of our table — the bar most "non-toxic" cookware marketing never clears.

Every claim, and where the proof stands

100% ceramic cookware (Versa, Traditions)

Xtrema publishes its testing program (SGS and labs in the USA, Hong Kong and China, LFGB standards) and states 15 years of passing California Prop 65 lead/cadmium leach standards. Independently, Mamavation commissioned an EPA-certified lab acid-bath leach test of the Versa pan and measured lead three orders of magnitude below California's warning threshold. Hobbyist XRF readings have detected metals in the ceramic body itself; leach testing — what actually transfers to food — is the exposure-relevant method, and it passes. Both facts are real; they measure different things.

Published testing: SGS et al. (brand-commissioned, posted) + independent EPA-certified lab via Mamavation — read it yourself (program ongoing; independent test published 2018+).

How to read this

“PFOA-free” is true of virtually every pan sold today and is not the same claim as “PFAS-free” — PTFE itself is a PFAS. If a coating’s chemistry matters to you, the questions that cut through are: what is the coating, and who published the test? Our PFOA vs PFAS guide covers the first; the main table tracks the second for every brand here.

We do not test cookware — we index published third-party lab results and public legal records, with attribution, and make no health claims. A verdict describes the state of the published evidence for specific marketing claims, not whether a pan is safe or dangerous. An allegation is not a finding; a settlement is not an admission; a lab report speaks only for the samples tested. If a brand publishes new evidence, the page changes — the source always wins.
