Foreign-based chemical control regulations, such as the Registration, Evaluation, Authorization, and Restriction of Chemicals (“REACH”) in the EU, the Chemical Substances Control Law (“CSCL”) in Japan, MEE Order No. 12 in China, and the Toxic Chemical Substance Control Act (“TCSCA”) in Taiwan for the production and distribution of chemicals in commerce and reporting of potential adverse effects;

Previous wording

In May 2020, five European countries began an initiative to restrict the manufacture, placing on the market and use of PFAS in the EU. In this regulatory process, more than 4,000 substances, including F-gases and fluoropolymers are being considered for potential broad regulatory action. On July 15, 2021, the countries submitted their restriction proposal, which informed ECHA of the intent to prepare a PFAS restriction dossier for fluorinated substances within a defined structural formula scope, including branched fluoroalkyl groups and substances containing ether linkages, fluoropolymers and side chain fluorinated polymers. The restriction dossier was submitted to ECHA in January 2023, and in February 2023 ECHA published a report and supporting annexes on the restriction proposal, which includes identified concerns for in-scope PFAS and their degradation products and the proposed restriction of a full ban with certain use-specific time-limited derogation periods. Comments were submitted from individuals and organizations during the consultation period in 2023 and the restriction dossier is being reviewed by RAC and SEAC. RAC and SEAC are focusing on the different sectors that are affected and elements of the proposal, and further meetings will be held in 2025. In November 2024, ECHA and the five European countries issued a progress update on the PFAS restriction, indicating that alternative restriction options, besides a full ban or a ban with time limited derogations, are being considered. The five national authorities who prepared the proposal are also updating their initial report to address the consultation comments, which will then be assessed by ECHA committees. The estimated earliest entry into force of restrictions is 2026, contingent upon timely completion of the remaining steps in the EU REACH restriction process.

In August 2025, the five national authorities reviewed over 5,600 comments from the 2023 consultation and updated their original restriction proposal. This revised version, called the Background Document, is now the basis for ECHA’s committee opinions and includes alternative restriction options instead of a full ban or a ban with time-limited derogations for certain applications. The document may still be updated further as the committees continue their evaluation. The estimated earliest entry into force of restrictions is 2027, contingent upon timely completion of the remaining steps in the EU REACH restriction process.

Previous wording

In March 2023, EPA proposed a NPDWR to establish Maximum Contaminant Levels ("MCL’s") for six PFAS, with PFOA and PFOS having MCLs as individual compounds (each proposed as 4 parts per trillion – (“ppt”)) and four other PFAS compounds, including HFPO Dimer Acid, having a hazard index approach limit on any mixture containing one or more of the compounds. The proposed PFAS NPDWR was subject to public comment through May 30, 2023, and on April 10, 2024 EPA issued its final rule, which included promulgating individual MCLs for PFOA and PFOS at 4ppt and individual MCLs for PFHxS, PFNA and HFPO Dimer Acid at 10ppt. In addition, EPA finalized a hazard index of 1 (unitless) as the MCL for any mixture of PFHxS, PFNA, HFPO Dimer Acid and PFBS. The final rule became effective 60 days from publication in the Federal Register and the compliance date for public water systems in the U.S. to meet the MCLs is five years from the publication date. In June 2024, we, as well as other organizations including the American Water Works Association and the American Chemistry Council, filed petitions for review of the final rule in the U.S. Court of Appeals for the D.C. Circuit. The appeal had been held in abeyance since February 2025 to allow EPA to review the underlying rule. In May 2025, EPA announced that it intends to retain the MCLs for PFOS and PFOA, with rulemaking for additional time for compliance, and to rescind the other MCLs and hazard index. In July 2025, EPA moved for the court to take the appeal out of abeyance in order for parties to complete briefing.

In July 2025, EPA moved for the court to take the appeal out of abeyance in order for parties to complete briefing. On September 11, 2025, EPA moved for partial vacatur of the regulation, requesting vacatur of its determination to regulate three individual compounds, including HFPO-DA, and mixtures of those compounds and another through a “hazard index”. EPA did not seek vacatur of the portions of the regulation governing PFOA and PFOS. Further briefing was ordered by the court, however this matter is now being held in abeyance due to the government shutdown.
