Diethanolammonium perfluorooctane sulfonate is a PFAS (per- and polyfluoroalkyl substance) salt of PFOS, a compound subject to severe international restrictions under the Stockholm Convention and domestic EPA regulatory action due to its persistence, bioaccumulation, and toxicity profile. US import volumes are extremely limited, with the United Kingdom and Germany as the only recorded supplier countries, reflecting the near-global phase-out of PFOS-based products. Importers should be aware that EPA's Significant New Use Rules (SNURs) under TSCA impose strict notification and approval requirements before this substance can be imported or used in the United States.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Under TSCA, PFOS and its salts — including the diethanolammonium salt — are subject to Significant New Use Rules (SNURs). Any importer must submit a Significant New Use Notice (SNUN) to EPA at least 90 days before importing, and EPA must review and clear the notice before the shipment can proceed. A TSCA certification is also required at the port of entry.
EPA has identified a narrow set of exempted or conditionally permitted uses for PFOS-related compounds, primarily in certain defense and semiconductor applications. Importers must document the specific end use and confirm it falls within an EPA-recognized exemption before filing a SNUN, as unauthorized importation can result in significant civil penalties.
