Thank you for your answer
As it is known that there are harmful non-stick coatings, the material quality should be explicitly stated in your sales documents. Legally speaking, you would be knowingly selling products that are harmful to health.

I don't have precise information on the exact material of the Dual Basket Airfryer NA352/09 baskets in my data. Available sources indicate that the inner lining is not ceramic and probably uses an unspecified non-stick coating, but the exact materials of the baskets are not explicitly mentioned. I recommend that you consult the product user manual or contact Philips customer service directly for this specific information.
