Stockholm Convention COP-12 (2025) amends Annex A to list chlorpyrifos, MCCPs, and LC‑PFCAs; and adopts an additional specific exemption for UV‑328

The Stockholm Convention COP-12 (Geneva, 28 April–9 May 2025) adopted amendments to Annex A adding chlorpyrifos, medium-chain chlorinated paraffins (MCCPs), and long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds as new POPs. COP-12 also adopted an amendment related to UV‑328 to add an additional specific exemption. Compliance teams should assess supply-chain and product impacts for these newly listed POPs and track any applicable exemptions and phase-out requirements as they are implemented domestically by Parties.
