Maine has issued its first ruling on Currently Unavoidable Use (CUU) proposals for PFAS. Out of 11 proposals reviewed, the Department of Environmental Protection (MDEP) recommended approval for only two. With the state’s prohibition on PFAS-containing products taking effect January 1, 2026, this outcome signals just how narrow CUU approvals will be. Manufacturers and importers now face urgent choices: find alternatives, adjust supply chains, or risk losing access to the Maine market.
Maine’s PFAS consumer products law bans the sale of most products with intentionally added PFAS beginning January 1, 2026. The only pathway for continued use is a CUU determination. This is granted only if PFAS is proven essential for health, safety, or critical societal functions and no reasonably available alternatives exist.
For products facing the 2026 ban, CUU requests were due by June 1, 2025. The rule adopted in April 2025 also extended submission timelines for future bans, allowing CUUs to be filed up to five years before a prohibition and no later than 18 months before.
The latest MDEP review shows CUU approvals are rare and subject to rigorous scrutiny. Manufacturers should not assume exemptions will be available. For most products, alternatives will be required to maintain market access.
MDEP reviewed proposals covering cookware (including small kitchen appliances), cleaning products, cosmetic packaging, and upholstered furniture. The two out of 11 proposals that were recommended for approval were both tied to specialized container components in cleaning products (e.g., internal cartridge valve and cap liner systems).
The rest, including cookware coatings, coffee maker parts, cosmetic packaging, and upholstered furniture, were denied. In rejecting these proposals, MDEP cited that alternatives were already “commonly known and readily available.”
Approved CUUs are time-limited. Both approvals expire on January 1, 2031, underscoring that exemptions are temporary and subject to reevaluation. CUU success is the exception, not the rule. Manufacturers must plan now to eliminate PFAS from their products.
Maine’s decisions carry significant implications for industry:
This isn’t just a Maine issue. By applying such a narrow CUU standard, the state is setting a precedent that other states, and potentially federal regulators, may follow. Manufacturers should treat Maine’s approach as an early signal of where PFAS regulation is headed nationwide.
With deadlines looming, manufacturers must act quickly:
