Editorial independence
Know Your Cookware does not accept manufacturer payments for placement, ranking, or favorable verdicts. We do not run sponsored reviews. A brand's tier (SAFEST / SAFE / CAUTION / AVOID) reflects what independent third-party testing shows — not commercial relationships.

Medical disclaimer
Information on Know Your Cookware is provided for general informational and educational purposes only. It is not medical advice. Cookware-related health questions — including suspected lead exposure, PFAS exposure, hemochromatosis, nickel allergy, and pregnancy-related cookware decisions — should be discussed with a licensed physician or qualified healthcare professional.
Nothing on this site should be construed as a substitute for medical evaluation, diagnosis, or treatment. We do not provide personalized medical advice through any channel.
Lab data interpretation
The site cites peer-reviewed studies, FDA guidance documents, state regulatory actions, and independent lab reports. Where citations exist, we link them. Where data is unavailable or contested, we say so.
XRF testing reads total content in a substrate. Leach testing reads migration into food. Both metrics are valid for different purposes; we distinguish them on each evidence page.
Verdict updates
Tier verdicts reflect available data at the time of publication. Brands may improve formulations, retest, or update certifications. We refresh verdicts when new third-party testing is published. If you believe a verdict is outdated, contact corrections [at] knowyourcookware [dot] com.
Limitation of liability
Use of this site is at your own risk. Know Your Cookware makes no warranties, express or implied, about the accuracy or completeness of any information presented. We are not liable for decisions made based on site content.
