TSCA PFAS Reporting Deadline Extended

On May 12, 2025, the U.S. Environmental Protection Agency (EPA) issued an interim final rule to amend the reporting period under the per- and polyfluoroalkyl substances (PFAS) reporting rules issued in October 2023 under the Toxic Substances Control Act of 1976 (TSCA). The rules require entities that manufactured or imported PFAS and/or PFAS-containing articles between January 2011 and December 2022 to report certain data. EPA first established a reporting window of November 12, 2024, to May 8, 2025. The window was moved to July 2025 to January 2026 (or July 2026 for small manufacturers exclusively importing regulated products) due to delays in development of the Central Data Exchange (CDX), EPA’s web-based reporting tool for information submitted under the TSCA PFAS reporting rules. If finalized, EPA’s proposed rule will again change the data submission period to April 13, 2026, to October 13, 2026, to allow the Agency “more time to prepare the reporting application to collect this data.” Note that the end date for small manufacturers reporting exclusively as article importers of regulated products will shift to April 13, 2027.

Within the reporting periods, entities must submit to EPA information regarding: the manufacturing company; the chemical identity, form, purpose and volume of the PFAS produced; byproducts generated during its manufacturing and disposal; environmental and health effects, worker exposure data and disposal data relating to the PFAS produced. While EPA has not proposed any changes to these substantive requirements, supplementary information accompanying the proposed rules indicates that the Agency may reopen portions of the underlying reporting rule to public comment, and that the delay will give the Agency time to consider comments and propose and finalize any modifications to the reporting rules.

The New Mexico Environment Department recently added guidance to its per- and polyfluoroalkyl substances (PFAS) website to assist consumers, businesses and manufacturers in their efforts to comply with New Mexico’s PFAS labeling requirements under the PFAS Protection Act. The guidance provides detailed instructions regarding the contents of the state’s PFAS label, as well as where to place and display the label on products, packaging, online sales platforms and complex durable goods. The guidance also establishes the process through which manufacturers can rely on labeling adopted in other states, outlines the procedures for those seeking waivers because their products contain intentionally added PFAS that will not come into direct contact with consumers during intended use, and describes the enforcement mechanisms and potential penalties for noncompliance under the Act.

After the U.S. Environmental Protection Agency (EPA) delayed the submission period for its one-time per- and polyfluoroalkyl substances (PFAS) reporting requirement under the Toxic Substances Control Act, Minnesota just extended its own (previously extended) PFAS products reporting deadline from July 1, 2026, to September 15, 2026. The Minnesota Pollution Control Agency cited challenges in collecting and submitting data under the state’s reporting rule, adopted in December 2025, as necessitating the delay. That rule requires manufacturers of intentionally added PFAS-containing products to submit a description of each product and the concentration and function of PFAS in it. Manufacturers unable to meet the new deadline may request a single, 90-day extension, which would extend reporting to December 2026. The Agency notes that 18 companies submitted reports ahead of the original deadline, data from which (except for protected trade secrets) is now publicly available. Given the fluidity of the rules and the deadlines, we continue to advise submitting closer to the (now later) end of the reporting period.
