Final rule adds sodium perfluorohexanesulfonate (PFHxS-Na) to TRI starting Reporting Year 2026

EPA issued a final rule implementing the statutory addition of one PFAS—sodium perfluorohexanesulfonate (PFHxS-Na; CASRN 82382-12-5)—to the EPCRA §313 Toxics Release Inventory list. The rule makes the chemical reportable beginning with Reporting Year 2026 (tracking starting January 1, 2026), with TRI reporting due July 1, 2027 for RY2026. Facilities subject to TRI should update chemical inventories, supplier communications, and TRI reporting workflows; PFAS listed under the NDAA mechanism are treated as chemicals of special concern (impacts Form A eligibility/de minimis considerations as applicable under TRI program rules).
