On September 30, 2022, California's governor signed Assembly Bill 1817, enacting a law to restrict PFAS in a range of textile products. The law would prohibit, beginning January 1, 2025, a person from manufacturing, distributing, selling, or offering for sale in the state a new textile article that contains regulated perfluoroalkyl and polyfluoroalkyl substances (PFAS).

The bill distinguishes outdoor gear and apparel designed for "severe conditions" and delays the applicability of the ban on those products to 2028 but requires as of January 1, 2025, a legible and easily discernible disclosure carrying the statement "made with PFAS chemicals" with any textile article. 

The prohibition on new textile articles is based on PFAS thresholds measured in total organic fluorine: a) commencing January 1, 2025, 100 parts per million, and b) commencing January 1, 2027, 50 parts per million.

The governor vetoed Assembly Bill 2247, a related bill that would have required the creation of a publicly accessible data collection interface for Perfluoroalkyl and polyfluoroalkyl substances (PFAS) and PFAS products and product components, involving multistate cooperation. The governor's veto message was based on concerns about the considerable cost of approving such an endeavor without consideration of the state budget by legislators.
