Maryland PFAS product requirements
Maryland's cosmetics rule lists 13 chemicals, not the PFAS class.
HB 643 prohibits thirteen specifically enumerated PFAS and their salts, drawn from the PFOA and PFOS families, so a cosmetics formulation can contain PFAS and still be lawful in Maryland while failing in California. Rugs, carpets and food packaging have been prohibited since January 1, 2024 under the George 'Walter' Taylor Act on the broader intentionally-added standard. Maryland also covers playground surfacing materials, effective October 2024 — a category almost no other state addresses.
