COP-12 adopts Annex A listings for chlorpyrifos, MCCPs and LC‑PFCAs; adds additional specific exemption for UV‑328

At the twelfth meeting of the Conference of the Parties (COP-12, 28 April–9 May 2025), Parties adopted decisions amending the Stockholm Convention annexes to (1) list chlorpyrifos in Annex A (elimination), (2) list medium-chain chlorinated paraffins (MCCPs) in Annex A, and (3) list long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds in Annex A (and referenced as Annex A/C in the research summary). COP-12 also adopted an amendment for UV‑328 in Annex A to add an additional specific exemption. Compliance teams should treat these as new/updated global POP obligations that can trigger downstream national implementation measures (production/use prohibitions, trade controls, exemptions/allowed uses tracking) and supply chain due diligence for affected substances and articles.
