PFAS Reporting Rule Delayed Again Amid Ongoing Rulemaking

EPA has delayed the start of the PFAS Reporting Rule reporting period for the third time as the agency finalizes amendments that would narrow the rule’s scope.

The reporting period will now begin January 31, 2027, or 60 days following the effective date of the final rule implementing the amendments, whichever is earlier.  EPA says that it expects to release the final rule “well before” the January 31, 2027, fallback date.

The extension will be published in the Federal Register on April 13, 2026, the same day the reporting period had been scheduled to begin.

Background

Promulgated under section 8(a)(7) of the Toxic Substances Control Act (TSCA), the PFAS Reporting Rule requires all persons who manufactured or imported PFAS for commercial purposes between 2011 and 2022 to report chemical information to EPA.  For most manufacturers and importers, the original reporting deadline was May 13, 2023.  However, EPA delayed the start of the reporting period in 2024 and again in 2025, citing technical difficulties with the reporting tool.

In the 2025 postponement, EPA also signaled that it was considering reopening the rule’s reporting requirements.  Subsequently, in November 2025, EPA released a proposed rule introducing various exemptions to the reporting requirements.  These include exemptions for mixtures and products containing de minimis PFAS concentrations, imported articles, and certain byproducts and impurities.
