EPA proposes scope/exemption changes to TSCA PFAS one-time reporting rule (including ≤0.1% threshold and imported articles)

EPA proposed amendments to the TSCA Section 8(a)(7) PFAS reporting and recordkeeping requirements to reduce potentially duplicative reporting. The proposal includes exemptions/limitations such as PFAS in mixtures/products at ≤0.1%, imported articles, and certain byproducts, impurities, R&D substances, and non-isolated intermediates. If finalized, these changes would materially affect who must report and what information is required for the one-time PFAS reporting covering 2011–2022 manufacturing/import.
