PFAS Toxic substances Environmental Protection Agency EPA Chemical Reporting Requirements Annual Declaration Chemical Import and Manufacture
On October 7, 2025, the U.S. Environmental Protection Agency (EPA) announced the automatic addition of sodium perfluorohexanesulfonate (PFHxS-Na) (CAS No. 82382-12-5) to the Toxics Release Inventory (TRI).
This action, mandated under the Fiscal Year 2020 National Defense Authorization Act (NDAA), follows EPA’s finalization of the “IRIS Toxicological Review of Perfluorohexanesulfonic Acid (PFHxS, CAS No. 335-46-4) and Related Salts.”
With this addition, 206 PFAS are now subject to TRI reporting, effective January 1, 2026.
Reporting Scope and Requirements
Facilities in designated industries that manufacture, process, or otherwise use TRI-listed chemicals must report annual data on the quantities released or managed as waste.
Starting January 1, 2026, facilities handling PFHxS-Na must track and report their activities as required under section 313 of the Emergency Planning and Community Right-to-Know Act.
Reporting Deadline: July 1, 2027
Preliminary 2026 TRI Data Release: July 2027
This addition supports EPA’s ongoing efforts to enhance transparency and public access to data on per-and polyfluoroalkyl substances (PFAS) in the environment and provides valuable information for both communities and policymakers
