Stockholm Convention COP-12 decisions adopt Annex A listings for chlorpyrifos, MCCPs, and LC‑PFCAs

At the 12th meeting of the Conference of the Parties (COP-12), Parties adopted decisions to amend Annex A (elimination) of the Stockholm Convention to list chlorpyrifos (decision SC-12/9), medium-chain chlorinated paraffins (MCCPs) (SC-12/10), and long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds (SC-12/12). For compliance teams, this is the international legal basis that triggers downstream implementation actions by Parties (national/regional bans or severe restrictions, plus any exemptions) and should be tracked for supply chain impacts on substances, mixtures, and articles.
