ECHA Opinions on PFAS: Restriction Ban With Targeted Derogation

The European Chemicals Agency (ECHA) has reached a critical milestone on per- and polyfluoroalkyl substances (PFAS). The agency's Risk Assessment Committee (RAC) recently finalized its scientific opinion backing broad PFAS restrictions, while the agency's Socio-Economic Analysis Committee (SEAC) agreed on a draft opinion that balances environmental urgency with industrial realities.

PFAS have long been prized for their benefits - resistance to heat, water, oil, and chemical reactions. That same durability, however, prevents them from readily breaking down in the environment. As a result, five member states proposed restricting PFAS in 2023, reflecting growing concern over the long-term environmental and health risks posed by more than 10,000 “forever chemicals” embedded across industries from semiconductors, cookware, and waterproof jackets to food packaging.

The dilemma faced by the committees on how to balance calls for a strict ban with concerns around economic viability was openly discussed during a recent ECHA Safer Chemicals podcast.

Opinion Based on Scientific Evidence: RAC

Roberto Scazzola, chair of the RAC, explained that PFAS' extreme persistence in the environment - rather than toxicity alone - justifies regulatory action. Once released, these substances remain in ecosystems for decades, accumulate over time, and potentially reach humans through water, soil, and food chains.

That persistence has led regulators to adopt a precautionary approach: PFAS are increasingly treated as “non-threshold” substances, meaning no level of exposure can be considered entirely safe. The implication is stark: any release, however small, contributes to long-term environmental accumulation, reinforcing the case for sweeping restrictions rather than targeted controls.

The key feature of the RAC opinion is its broad definition of PFAS based on criteria from the Organization for Economic Cooperation and Development (OECD), covering any chemical containing at least one fully fluorinated carbon group. The grouping approach is designed to prevent substitution by capturing the entire class rather than individual substances.

In practice, this significantly expands the number of affected products and sectors. ECHA estimates that roughly 270,000 tons of PFAS were used in major applications like textiles, fluorinated gases, and transport across the European Economic Area in 2020.

Regulators have also included fluoropolymers in the PFAS restriction due to risks arising across their life cycles, although there is limited evidence of their bioaccumulation and ecotoxicity. These highly stable, heat- and chemical-resistant plastics - widely used in products such as non-stick cookware - can generate PFAS emissions during manufacturing processes and waste treatment, including incineration, by releasing additional persistent compounds and micro- or nano-sized particles. As a result, the RAC concluded that the broader environmental footprint of fluoropolymers provides sufficient grounds for regulatory action.

The RAC opinion covers fluorinated gases as well. They are a highly volatile subset of PFAS and can spread widely through the atmosphere, contributing to pollution even in remote regions such as the Arctic. Widely used in refrigeration, cooling systems, and electronics, they are both persistent and mobile, with some also carrying significant global warming potential. A key concern is their ability to degrade into other PFAS compounds, including trifluoroacetic acid (TFA), which is now under increasing regulatory scrutiny.

The proposal has already raised concerns among industry groups, which warn that a blanket approach could disrupt critical supply chains (see 3E article). Highly technical sectors - such as electronics, aerospace, and healthcare - face challenges, as alternatives to PFAS are often limited or not yet commercially viable. Scazzola admitted during the podcast that RAC's approach was a purely scientific, evidence-based risk assessment, whereas the SEAC can also consider factors beyond risk alone.

Risk vs. Reality: SEAC's Opinion

Maria Ottati, chair of the SEAC, explained in the podcast that the committee's recent publication also launches a 60-day consultation on the draft opinion, with stakeholders invited to submit comments until May 25, 2026. The SEAC draft opinion supports a broad restriction but recommends targeted exemptions where the benefits to society outweigh the costs.

At the center of this opinion is the assessment of viable alternatives. Where substitutes exist and are cost-effective, the case for restrictions is still complex, but relatively straightforward. In consumer applications such as cosmetics, textiles, and ski wax, the SEAC has concluded that alternatives exist and that exemptions are largely unjustified.

The picture is markedly different in high-performance and complex industrial and technical uses. In sectors such as semiconductors, advanced electronics, and certain medical devices, PFAS often play a critical role in ensuring performance and safety. In these cases, viable alternatives may be unavailable, insufficiently developed, or unable to meet regulatory standards. The consequences of substitution could therefore extend beyond higher costs, potentially affecting product quality, safety, and availability - with knock-on effects for public health and industrial competitiveness.

However, the potential impacts extend beyond industry. Restrictions could affect employment, product performance, and even environmental outcomes if alternatives prove less efficient. In some cases, the absence of PFAS could lead to higher emissions elsewhere.

Therefore, regulators are considering time-limited derogations, typically ranging from five to 12 years depending on the availability of viable alternatives. These transition periods aim to provide industry with time to innovate while avoiding unnecessary delays in reducing emissions.

The proposed transition periods - based on the RAC opinion, reviewed and adjusted by SEAC for the consultation - aim to provide industry with time to innovate while avoiding unnecessary delays in reducing emissions.

This would largely be in line with the SEAC's recommendation of a broad restriction framework combined with targeted derogations - temporary or conditional exemptions for uses where alternatives are not yet viable or where the economic cost of an immediate ban would outweigh benefits - which is intended to ensure that the regulation remains proportionate. The committee has assessed uses on a case-by-case basis, grouping them into the following three categories of derogations:

• Not justified
• Clearly needed
• Insufficient data prevents a firm conclusion

Notably, even where derogations are recommended, the SEAC stresses that they should be seen as necessary but not necessarily sufficient. Given the breadth of the proposed restrictions and gaps in available data, additional exemptions may ultimately be necessary. This reflects one of the key challenges in regulating PFAS: the sheer diversity of applications, many of which remain only partially understood.

Uncertainty is particularly pronounced in newly identified sectors that were not fully assessed during the initial evaluation. For these areas, the SEAC has proposed temporary, time-limited derogations while further analysis is carried out - effectively buying time for regulators to gather data and refine the approach.

From Scientific Opinion to Political Decision

The regulatory timeline shows a clear path forward:

• March 2026: RAC adopts final scientific opinion; SEAC agrees on draft opinion.
• Spring 2026: 60-day public consultation on SEAC draft opinion ends on May 25.
• End of 2026: SEAC finalizes its opinion.
• From 2027: European Commission begins drafting legislation.

This regulatory momentum is already shaping market behavior. Companies are increasingly investing in substitute technologies in anticipation of tighter rules, suggesting that the restriction could act as a catalyst for industrial transformation. However, this transition is unlikely to be uniform. While some sectors are well positioned to adapt quickly, others face structural constraints that could slow progress or require prolonged support.

There are also questions about enforceability, as even well-designed rules will depend on their consistent application across European Union (EU) member states.

And this is likely to have far-reaching implications, not only for Europe's chemicals sector but also for its wider industrial strategy. A stringent approach could position the EU as a global leader in regulating persistent pollutants, while a more flexible framework may prioritize economic resilience and technological feasibility. In either case, the decision will shape the trajectory of both environmental policy and industrial competitiveness for years to come.
