The Cookware Sustainability Alliance (CSA) announced on January 9, 2025, that it has filed suit in the U.S. District Court for the District of Minnesota, seeking a preliminary injunction of Minnesota’s ban on the sale of cookware containing intentionally added per- and polyfluoroalkyl substances (PFAS). CSA v. Kessler (No. 0:25-cv-00041). According to CSA, the chemical coating on nonstick cookware contains fluoropolymers, which “are fundamentally different compounds from the chemicals that have motivated concerns about PFAS.” CSA claims that Minnesota’s ban violates the U.S. Constitution’s prohibition on individual states regulating interstate commerce and has raised other constitutional challenges to Minnesota’s statute. CSA states that it has offered to work cooperatively with Minnesota “to secure an exemption for fluoropolymer coated nonstick cookware because of their low-risk profile.”
