Lithium perfluorooctane sulfonate (lithium PFOS) is a per- and polyfluoroalkyl substance (PFAS) subject to intensifying regulatory scrutiny under EPA frameworks governing persistent organic pollutants. Historically used as a surfactant and processing aid in electroplating, semiconductor manufacturing, and specialty coatings, its import and use face restrictions tied to the Stockholm Convention and domestic PFAS action plans. Importers should verify current EPA admissibility requirements and any applicable Section 301 exposure before shipment, as the regulatory landscape for PFOS salts continues to evolve rapidly.

Lithium PFOS falls under EPA oversight as a PFAS chemical subject to the Toxic Substances Control Act (TSCA). Importers may need to comply with TSCA Section 5 or Section 13 requirements, and the substance is also implicated under Stockholm Convention obligations that the US has adopted domestically. Consulting a licensed customs broker and an environmental compliance specialist is strongly recommended before importation.
Lithium PFOS has been used primarily in electroplating bath additives, semiconductor photolithography, and specialty fire-suppression formulations. Its use has declined sharply due to regulatory restrictions, and many end-use sectors have shifted to alternative chemistries.
