As of January 1, 2025, multiple states began prohibiting the sale or distribution of any juvenile product containing intentionally added PFAS chemicals. MAS Testing has added PFAS screening to its suite of accredited testing services to help manufacturers of children's products get ahead of these expanding regulations.

Per- and polyfluoroalkyl substances (PFAS) are a class of thousands of "forever chemicals" that have been used in a wide variety of products since the 1950s. Generally, they are found in nonstick coatings on packaging and cookware, stain-resistant clothes and carpets, paints and coatings, firefighting foam, wire jackets, cosmetics and hygiene products, and many other products used daily.
