POPRC-21 follow-up: call for comments/new information on revised indicative lists for LC‑PFCAs, PFOA and PFHxS (deadline 31 Mar 2026)

The Stockholm Convention Secretariat (POPRC intersessional follow-up) invited Parties and observers to submit new information and comments on revised indicative lists that clarify the substance scope captured by the existing listings for (1) long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds, (2) PFOA, its salts and PFOA-related compounds, and (3) PFHxS, its salts and PFHxS-related compounds. The stated submission deadline is 31 March 2026 (letter date 28 January 2026). These indicative lists are used to interpret which specific substances/precursors are covered, impacting compliance scoping, supply-chain declarations, and analytical screening programs.
