,On April 14, 2026, the World Trade Organization (WTO) circulated addendum G/TBT/N/USA/1742/Rev.2/Add.1 submitted by the United States, announcing the publication and entry into force of a final rule revising the reporting timeline under the Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) Reporting and Recordkeeping Rule. The measure is issued by the U.S. Environmental Protection Agency (EPA). The final rule modifies the start of the submission period for PFAS reporting under the Toxic Substances Control Act (TSCA). Under the revised timeline, the reporting period will begin on January 31, 2027, or 60 days after the effective date of a forthcoming final rule addressing the substantive requirements of the PFAS Reporting Rule, whichever occurs earlier. The revision aims to provide regulated entities with additional clarity and preparation time before reporting obligations commence. The rule was published and entered into force on April 13, 2026, and forms part of broader regulatory efforts to improve data collection and oversight of PFAS substances.
