EPA issued an interim final rule extending the TSCA Section 8(a)(7) PFAS reporting submission period. The rule provides additional time due to EPA's inability to conduct planned beta testing of the CDX reporting application. Under this interim rule, most manufacturers must submit reports by October 13, 2026, while small businesses reporting solely on PFAS contained in imported articles have until April 13, 2027.
Under TSCA Section 8(a)(7), the US Environmental Protection Agency (EPA) requires manufacturers (including importers) of per- and polyfluoroalkyl substances (PFAS) to submit one-time retrospective reports covering PFAS manufactured or imported since January 1, 2011. The rule aims to enhance federal oversight by collecting detailed information on PFAS production volumes, uses, exposure pathways, and potential environmental and human health impacts. Reporting opens April 13, 2026; submissions are due by October 13, 2026, with small manufacturers allowed until April 13, 2027
