Le Creuset
The pot itself is enameled cast iron and fully plastic-free — no coatings, liners, or gaskets in the food path. The one concession is the default lid knob, which ships as phenolic plastic but is easily swapped for a stainless one Le Creuset sells separately, so the plastic is both minor and removable. The brand doesn't market plastic-free, but the material set (cast iron plus vitreous enamel) leaves little room for hidden plastic. It's a case where the only plastic is an accessory you can eliminate outright.
How clear are their specs?
Materials are simple and stated — enameled cast iron body, phenolic default knob — and the stainless knob upgrade is openly sold, so buyers know exactly where the plastic is.
Lead testing disclosure
Le Creuset publishes a "Chemical Disclosures for Cookware" page stating lead is not used and that cadmium pigments are locked in a special anti-acid enamel fritt, and cites compliance with California Prop 65 - but does not publish its own lab report or actual ppm/detection-limit numbers, and does not say which colors are cadmium-free. Independent XRF testing (Lead Safe Mama) has found high cadmium levels in colored exterior enamels (as high as ~17,700 ppm in yellow) and lead/cadmium traces in some food-contact interiors of newer pieces; Le Creuset has not published its own testing to referee this.
