EPA finalized the addition of sodium perfluorohexanesulfonate (PFHxS‑Na) to the TRI list as a PFAS chemical of special concern. TRI-covered facilities that manufacture, process, or otherwise use PFHxS‑Na must begin tracking for Reporting Year 2026 (starting Jan 1, 2026). The research summary indicates a 100 lb threshold and first TRI reporting due July 1, 2027, which compliance teams should incorporate into TRI applicability screening, supplier data collection, and environmental reporting workflows.
