Maine PFAS Products Ban: The 2024 Amendment's Effective Repeal of General Reporting in Favor of the "Currently Unavoidable Use" (CUU) Framework
ENFORCEMENT TIMELINE
Second-phase ban effective January 1, 2026; full ban by 2032 (Currently Unavoidable Use framework in operation)
Overview
Maine enacted, in 2021, a pioneering regulatory framework requiring comprehensive advance notification for all products containing intentionally added PFAS (38 M.R.S. §1614). However, due to practical difficulties in implementing this general notification requirement, a 2024 statutory amendment (Public Law 2023, c.630, effective April 2024) repealed the general notification obligation that had originally been scheduled to take effect January 1, 2025, and replaced it with a narrower reporting regime limited to product categories granted a "Currently Unavoidable Use" (CUU) designation.
The sales prohibition schedule is staggered by product category: carpets/rugs and fabric treatments have been banned since January 1, 2023; beginning January 1, 2026, the ban expands to cleaning products, cookware, cosmetics, dental floss, children's products, menstrual products, textile products (with certain exceptions), ski wax, and upholstered furniture; beginning January 1, 2029, the ban is scheduled to expand further to artificial turf and severe-weather outdoor apparel (unless PFAS use is disclosed); and by January 1, 2032, all products containing intentionally added PFAS are, in principle, prohibited (except for uses granted a CUU designation). The regulations governing the CUU designation process itself (amended Chapter 90) took effect October 7, 2025, and the Department of Environmental Protection (DEP) plans to continue reviewing additional CUU applications from spring 2026 onward.

October 7, 2025: Regulations governing the CUU designation process (amended Chapter 90) take effect
January 1, 2026: Ban expands to cleaning products, cookware, cosmetics, dental floss, children's products, menstrual products, textile products, ski wax, and upholstered furniture

Business Impact
Manufacturers should note that Maine's original comprehensive advance-notification requirement no longer applies following the 2024 amendment, and that compliance obligations now depend on whether a given use has received a CUU designation. Companies with products in the January 1, 2026 expansion categories should confirm whether their specific use case has been or could be granted CUU status, since this designation—rather than the general reporting mechanism originally contemplated—is now the primary compliance pathway for products that cannot yet be reformulated.
