On November 20, 2025, U.S. Washington State Department of Ecology (DoE) adopted amendments to Chapter 173-337 WAC: Safer Products Restrictions and Reporting. 

The amended rule restricts the manufacture, sale, and distribution of the three consumer product categories in Washington State that contain intentionally added per- and polyfluoroalkyl substances (PFAS) and also requires manufacturers to report the intentional use of PFAS for nine other consumer product categories. 

In addition, the amendment added a de minimis threshold of total fluorine above 50 parts per million (ppm) to presume the intentional addition of PFAS for all 12 consumer product categories. 

Following is the summary of PFAS requirements in the amendment:
