Maine sets a national precedent by phasing out nearly all non-essential PFAS use, sparking regulatory, health, and industry debates.

Maine’s Bold Action Against ‘Forever Chemicals’: The PFAS Ban and What It Means

Maine has taken a historic step as the first U.S. state to ban virtually all non-essential uses of PFAS (‘forever chemicals’) in consumer products, setting the standard for environmental policy and public health protection nationwide.^*

What Are PFAS and Why Are They Called ‘Forever Chemicals’?

Per- and polyfluoroalkyl substances (PFAS) are a family of synthetic chemicals renowned for their resistance to water, grease, and stains, but also infamous for their environmental persistence.^*

Origins: PFAS have been used since the 1940s in products ranging from nonstick cookware to firefighting foam and cosmetics.
Durability: These chemicals do not break down easily in the environment or in living tissues, earning them the nickname ‘forever chemicals.’³
Health Risks: Linked to cancer, kidney disease, immune disorders, low birth weights, and more.³

Overview of Maine’s PFAS Ban Legislation

In 2023, Maine’s legislature initiated the nation’s broadest ban, targeting all non-essential uses of PFAS. The law was amended and expanded in 2024 to clarify its reach, set deadlines, and structure exemptions.¹

Signed into law: April 16, 2024.¹
Phased rollout: Bans begin January 1, 2026, with more product categories woven in over time (2029, 2032, 2040).¹
Enforcement: Managed by Maine’s Department of Environmental Protection (DEP).

How the Ban Is Being Phased In

Year	Affected Products
2026	Consumer goods like ski wax, cosmetics, cleaning agents, and nonstick cookware
2029	Expanded product categories (details forthcoming from DEP)
2032	Manufacturing and electronic equipment
2040	Final categories for phase-out (pending DEP review)

This gradual approach gives manufacturers time to adapt, identify alternatives, and apply for special exemptions.¹

Key Provisions and Exceptions: The ‘Currently Unavoidable Use’ (CUU)

Recognizing the complexity of industrial supply chains and essential public needs, Maine incorporated a ‘Currently Unavoidable Use’ (CUU) exemption. If a manufacturer can prove that PFAS is absolutely essential for health, safety, or the functioning of society and no viable alternative exists, a product may be granted a temporary exception.²

Application process: Manufacturers must submit CUU proposals to DEP for review and public comment.
Strict criteria: CUU is only considered for uses deemed ‘essential’ and ‘without alternatives.’
Timeline: DEP reviews and updates CUU lists periodically, with new categories announced before each ban phase.²

DEP’s Decisions on Exemptions

In July 2025, DEP considered 11 exemption proposals, including cookware, cleaning goods, furniture, and cosmetic containers.²³

Cookware: Despite industry pressure, nonstick cookware was denied a CUU exemption, as alternatives are available (e.g., stainless steel, cast iron, ceramic).³
Other rejected exemptions: Kitchen appliances, coffee makers, electric fragrance warmers, certain cleaning product components, and furniture.
Approved CUU: Two cleaning product container components (vented cap liner and internal cartridge valve) were permitted because they are vital for product safety and performance.²⁴

Public Health and Environmental Justification

The ban is not just regulatory—it is a response to mounting scientific evidence about the harms of PFAS exposure.³

Health impacts: PFAS has been linked to:

Cancers (testicular, kidney, others)
Liver and kidney disease
Thyroid abnormalities
Reproductive and developmental disorders
Immune suppression
Low birth weight and birth defects

Environmental persistence: PFAS compounds do not naturally break down, contaminating soil, air, water, and biota indefinitely.
Bioaccumulation: PFAS can build up in food chains, posing long-term risks even at low concentrations.

Community and Legislative Support

Maine’s ban received momentum from:

Public health advocates and medical organizations
Environmental groups and local communities
Bipartisan legislative engagement

Industry lobbying to exempt cookware and other convenience products was repeatedly rebuffed, citing strong community and expert backing for a comprehensive ban.³⁴

Economic and Industry Impact: Challenges and Opportunities

The ban presents major challenges, especially for manufacturers and distributors of products containing PFAS.

Many consumer goods (from cookware to cosmetics) require reformulation or replacement of PFAS components.
Electrical and industrial products with PFAS internal components also face deadlines for compliance.¹
Manufacturers must stay up-to-date on product lists, new exemptions, and DEP communications to avoid unintentional violations.²
Transition periods encourage technological innovation and market development of safer alternatives.

For products with critical safety or performance needs, the CUU route offers a temporary lifeline—but the state is clear: such exemptions are narrow, rigorously scrutinized, and designed to sunset as soon as alternatives are available.

The Role of the Maine DEP and Board of Environmental Protection

Implementation hinges on ongoing public engagement and regulatory updates.

DEP: Reviews CUU proposals, recommends acceptance or rejection, oversees the ban phase-in, and advises the Board of Environmental Protection (BEP).
BEP: Final authority for exemptions, conducts hearings, accepts public comment, renders decisions.³⁴
Manufacturers: Obliged to track DEP rulemaking, update product lines, and demonstrate compliance.

National Ripple Effects and State-Level Policy Landscape

Maine’s ban is influencing a wave of PFAS policies across the U.S., with at least 10 states now enacting some form of PFAS product prohibition.²

States like Minnesota, California, and New Mexico have either adopted or are actively considering similar broad bans.
Other states restrict PFAS in specific products (e.g., carpets, rugs, personal care items).
Federal regulatory frameworks remain under development; Maine serves as a model for comprehensive action.
Manufacturers/importers must navigate a patchwork of state requirements, especially for nationally distributed products containing PFAS.

Industry Response: Adaptation and Opposition

National industry groups and major consumer product manufacturers have pressed for broader CUU carve-outs, especially for cookware and electronics.
DEP consistently rebuffed attempts to expand exemptions absent clear proof of essentiality and lack of alternatives.³⁴
Some sectors report rapid innovation in PFAS-free alternatives, while others (high-tech and industrial markets) continue to struggle.

Frequently Asked Questions (FAQs)

Q: What products will be banned first under Maine’s PFAS law?

A: Starting January 1, 2026, consumer products like ski wax, cosmetics, cleaning agents, and nonstick cookware containing intentionally-added PFAS will be banned.¹³

Q: How does the ‘Currently Unavoidable Use’ exemption work?

A: Manufacturers can apply to Maine DEP for a CUU designation if they can prove that a product’s PFAS is essential and alternatives are not available. DEP reviews each submission based on stringency and public comment.²

Q: Why was nonstick cookware denied a CUU exemption?

A: DEP found that alternatives to PFAS nonstick coatings exist (e.g., ceramic, cast iron) and the convenience of nonstick surfaces does not qualify as ‘essential’ under the law.³

Q: What health risks are associated with PFAS?

A: PFAS exposure is linked to several serious health issues, including cancers, kidney and liver disease, immune system disruption, thyroid abnormalities, and developmental problems.³

Q: Are there other states banning PFAS?

A: Yes. At least 10 states have some form of PFAS product prohibition, with Maine’s being the broadest and serving as a national precedent.²

Q: What should manufacturers do if they sell PFAS-containing products in Maine?

A: Manufacturers must review Maine’s DEP guidance, monitor prohibited categories for their product types, apply for CUU if applicable, and plan for product reformulation or withdrawal prior to phase-in dates.¹

The Road Ahead: Maine’s PFAS Ban as National Model

Environmental leadership: Maine has demonstrated decisive action, balancing environmental protection and pragmatic regulatory exemption.
Policy influence: Other states and potential federal agencies may follow suit, incorporating stringent definitions and tight exemption protocols.
