Scientific Progress and Outlook of the EU REACH PFAS Restriction Proposal
The review of the EU PFAS restriction proposal continues to advance steadily. Based on stakeholder input, authorities have updated the background documents and expanded the scope to cover additional industrial sectors. 2026 is expected to be a critical milestone, with scientific committees scheduled to issue assessment opinions in March and again toward the end of the year to help shape the future regulatory framework. The final opinion is expected by the end of 2026.
Background: PFAS Restriction Proposal Under REACH Since 2023
Since 2023, the proposed restriction of per- and polyfluoroalkyl substances (PFAS) under the EU REACH Regulation—jointly submitted by Denmark, Germany, the Netherlands, Norway, and Sweden—has attracted extensive stakeholder feedback. Between 2024 and 2025, the European Chemicals Agency (ECHA) has actively advanced the scientific review process through a rolling evaluation and revision approach, seeking a balance between environmental protection and industrial practicality. The overarching objective is to reduce PFAS emissions into the environment while enhancing product safety for human health.
A six-month public consultation was conducted from March to September 2023, during which more than 5,600 scientific and technical comments were submitted. Based on this feedback, the proposing authorities have continuously updated and refined the proposal documentation, providing the foundation for opinions by ECHA’s two scientific committees—the Risk Assessment Committee (RAC) and the Socio-Economic Analysis Committee (SEAC).
2025 Review: Phased Assessment and Horizontal Issues
By late 2025, the review entered the stage most closely watched by industry stakeholders—the discussion of “horizontal issues.” These elements will determine the practical operability of future regulation and form the core of deliberations ahead of the 2026 finalization:
- Definition of concentration limits: At what PFAS content does a product become non-compliant? This decision is expected to shape global chemical testing standards and compliance costs across supply chains.
- Treatment of spare parts: For high-value, long-lifecycle equipment such as semiconductor manufacturing tools or vehicles, how should PFAS-containing legacy spare parts be handled? This directly affects whether existing assets may be forced into premature retirement.
- Recycling, monitoring, and enforcement feasibility: How should PFAS-containing waste be safely managed? Do customs and environmental authorities have sufficient technical capability to reliably detect restricted substances? Regulators are seeking a compromise between regulatory ambition and current technical limitations.
Timeline for Final Opinions
ECHA’s scientific assessment process is expected to continue until the end of 2026. Key upcoming steps include:
- SEAC draft opinion consultation: Following the March 2026 committee meeting, ECHA plans to launch a 60-day public consultation on SEAC’s draft socio-economic opinion.
- Final opinion expected: SEAC is expected to adopt its final opinion by the end of 2026, marking the conclusion of ECHA’s scientific evaluation phase.
Final regulatory decisions will then be made by the European Commission in consultation with EU Member States. The outcomes of the 2026 review will formally usher the global PFAS supply chain into a new era of regulatory compliance.
