PFAS: United States Key Regulatory Developments in 2025

PFAS: United States Key Regulatory Developments – Whitepaper Overview:

In 2025, PFAS (Per- and Polyfluoroalkyl Substances) regulations in the United States are rapidly expanding and becoming more complex, driven by both federal and, especially, state level legislation, which primarily focuses on phasing out and prohibiting PFAS in a wide range of consumer products.

PFAS is known to be used in many consumer products including EEE (electronics), appliances, semiconductors; and, during 2025, bills and rules on PFAS have covered a particular set of household products including apparel; carpets and rugs; cleaning products; cookware; cosmetics; dental floss; textiles, fabric treatments; children’s (juvenile) products; menstrual products; ski wax; packaging; upholstered furniture; and in manufacturing – for its nonstick, repellant, and water resistant properties.

PFAS is often referred to as a “forever chemicalˮ in that it does not break down and can persist for decades. Environmental rules now also propose to ban PFAS from its air and water releases.

This whitepaper is an overview of the regulation of PFAS in the US at the federal and state level in 2025. It provides an update on legislation and rules affecting product manufacturing, sale, distribution, and new registration and reporting requirements.
