Washington State Expands PFAS Restrictions

/in ,

Last month, a Washington State Department of Ecology rule expanding the state’s restrictions on PFAS took effect.  The rule adds three new product categories subject to prohibition and imposes new reporting requirements for manufacturers of nine additional categories.

Beginning January 1, 2027, the manufacture or sale of the following products containing intentionally added PFAS will be prohibited in Washington:

  • Apparel and accessories
  • Automotive washes
  • Cleaning products

The rule includes a sell-through provision allowing the continued sale and distribution of products produced prior to the prohibition’s effective date.

Manufacturers of certain products containing intentionally added PFAS will also be subject to new reporting obligations.  By January 31, 2027, and annually thereafter, manufacturers of the following products must submit a notification to the Department of Ecology:

  • Apparel intended for extreme and extended use
  • Footwear
  • Gear for recreation and travel
  • Automotive waxes
  • Cookware and kitchen supplies
  • Firefighting PPE
  • Floor waxes and polishes
  • Hard surface sealers
  • Ski waxes

Pursuant to WAC 173-337-060, the notification must include the name and CAS number of each intentionally added PFAS, the applicable product category and component, a description of the PFAS function, the concentration range, contact information, and any other information the reporting party deems relevant to appropriate product use.

The rule also establishes a rebuttable presumption that PFAS have been intentionally added when total fluorine is detected above 50 parts per million in the newly regulated product categories.  This represents a departure from earlier PFAS restrictions, under which the detection of any total fluorine was sufficient to trigger the presumption.

Existing Restrictions

The rule was promulgated under Washington’s Toxic Pollution Law, which is implemented by the Safer Products for Washington program.  Through the program, the Department of Ecology prioritizes chemicals, identifies products, and conducts rulemakings to prohibit or otherwise restrict their manufacture or sale.

A previous round of PFAS prohibitions, which took effect in 2025, applied to aftermarket stain- and water resistance treatments and to carpets and rugs.  The department also prohibited intentionally added PFAS in indoor leather and textile furniture and furnishings beginning in 2026, while imposing annual reporting requirements for outdoor leather and textile furniture and furnishings starting in 2025.

Other products subject to restrictions or reporting requirements under the program include ortho-phthalates in vinyl flooring and personal care product fragrances, organohalogen flame retardants in electric and electronic products, flame retardants in recreational polyurethane foam, and phenolic compounds in laundry detergent, food and drink can linings, and thermal paper.
