An official Stockholm Convention BAT/BEP meeting page indicates an implementation work programme to update Best Available Techniques/Best Environmental Practices guidance to reflect recent Stockholm Convention outcomes: incorporating MCCPs into SCCPs-related guidance, including LC‑PFCAs in PFOS/PFOA-relevant guidance, updating UV‑328 BAT/BEP guidance reflecting COP-12 exemption amendments, and considering in June 2026 whether to develop BAT/BEP guidance for chlorpyrifos. For compliance teams, these updates can affect operational expectations for controlling releases and managing wastes/industrial processes linked to newly listed POPs and exemptions.
The EU amended Annex I of the EU POPs Regulation (Regulation (EU) 2019/1021) via a delegated act addressing perfluorooctane sulfonic acid (PFOS). The update aligns the PFOS entry to cover “PFOS, its salts and PFOS-related compounds”, tightens unintentional trace contaminant (UTC) limits (including a separate limit for the sum of PFOS-related compounds), and deletes the Annex I specific exemption for PFOS use as a mist suppressant for non-decorative hard chromium (VI) plating. The research text notes deferred applicability for parts of the Annex starting 3 Dec 2025, which compliance teams should treat as the date when the updated PFOS conditions/limits become applicable for substances/mixtures/articles placed on the market or managed under POPs controls.
The European Commission adopted and published Commission Delegated Regulation (EU) 2025/718 amending Regulation (EU) 2019/1021 (EU POPs Regulation) as regards perfluorooctane sulfonic acid (PFOS) and its derivatives. The legal act specifies that certain points in the Annex apply from 3 December 2025. EU compliance teams should review the amended Annex I provisions for PFOS (including any revised concentration limits, scope, or derogations) and ensure affected products, articles, and waste streams are assessed against the updated requirements by the stated application date.
The European Commission adopted and published Commission Delegated Regulation (EU) 2025/718 amending Annex I of Regulation (EU) 2019/1021 (EU POPs Regulation) as regards PFOS and its derivatives. The delegated act is published in the Official Journal (OJ L, 2025/718, 27.6.2025) and enters into force 20 days after publication; however, the act specifies delayed applicability for parts of the Annex (points 2 and 3) from 3 December 2025. Compliance teams should review the revised Annex I PFOS provisions, ensure product/material and waste streams are assessed against the updated PFOS requirements, and plan for controls applicable from 3 Dec 2025 as stated in the act.
The Conference of the Parties adopted Decision SC‑12/10 to list medium‑chain chlorinated paraffins (MCCPs) in Annex A (elimination) of the Stockholm Convention, with specific exemptions/conditions in the decision text. This listing obligates Parties to eliminate MCCPs subject to exemptions, and will cascade into national restrictions impacting manufacturing, use in articles, and waste management considerations. Compliance teams should evaluate MCCPs use (e.g., in plastics/rubber, sealants, coatings) and monitor implementing restrictions and any exemption conditions.
The Conference of the Parties adopted Decision SC‑12/9 to list chlorpyrifos in Annex A (elimination) of the Stockholm Convention (with specified exemptions per the decision). This global listing triggers Parties’ obligations to prohibit/eliminate the chemical subject to any exemptions and drives national implementing measures. Compliance teams should assess chlorpyrifos presence in products and supply chains and track any allowed exemptions and phase-out timelines under applicable national laws implementing the Convention.
The Conference of the Parties adopted Decision SC‑12/14 amending Annex A in connection with UV‑328 by adding an additional specific exemption (described in the research as certain aircraft-related uses, expiring end of 2030). This change is relevant for companies manufacturing/using UV‑328 in exempted applications and for downstream users who must track whether an intended use remains covered by an exemption and for how long, as national implementation measures may rely on the Convention’s exemption parameters.
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.
The Conference of the Parties adopted Decision SC‑12/12 to list long‑chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds in Annex A (elimination) of the Stockholm Convention, with specific exemptions as set out in the decision. This expands global POP controls over PFAS substances and affects chemical manufacturing, article production, and supply-chain compliance programs. Compliance teams should assess whether LC‑PFCAs (or related compounds) are present in materials, process aids, or articles and monitor how Parties implement the listing domestically.
The Stockholm Convention Secretariat’s Registers of Specific Exemptions page for Annex A chemicals indicates the register incorporates the UV‑328 amendment provisions, and separately notes that the amendments listing chlorpyrifos and MCCPs were not incorporated because they had not yet entered into force (per the register page statement). For compliance teams, this affects how exemptions and their availability are tracked in the Convention’s official register and helps determine which COP-adopted changes are reflected in the operational exemption registry.
At the twelfth meeting of the Conference of the Parties (COP‑12) to the Stockholm Convention, Parties adopted decisions to list (i) chlorpyrifos, (ii) medium-chain chlorinated paraffins (MCCPs), and (iii) long-chain perfluorocarboxylic acids (LC‑PFCAs, C9–C21), their salts and related compounds, as new POPs under Annex A. This global decision drives subsequent national/regional implementation measures (e.g., import/export/manufacture prohibitions, product restrictions, and potential exemptions) and should be reflected in global product stewardship and trade compliance screening for regulated POPs content.
The BRS Secretariat press release closing the 2025 COP meetings (including Stockholm Convention COP-12) summarizes that Parties agreed to list chlorpyrifos, medium-chain chlorinated paraffins (MCCPs), and long-chain perfluoroalkyl carboxylic acids (LC‑PFCAs) for elimination under the Stockholm Convention, and notes time-bound exemptions for UV‑328 (as referenced in the COP-12 outcomes summary). Compliance teams should treat this as confirmation of global treaty-level listing decisions that drive national implementation measures (bans/restrictions and exemptions) and supply-chain impacts for products/mixtures/articles containing these chemicals.
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.
Official Stockholm Convention COP-12 outcomes include decisions to list chlorpyrifos, medium-chain chlorinated paraffins (MCCPs), and long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds as persistent organic pollutants for elimination (Annex A). This global listing triggers follow-on obligations for Parties to implement prohibitions/restrictions and manage any allowed specific exemptions through domestic/regional implementing measures, affecting global supply chains for chemicals and articles containing these substances.
The Stockholm Convention COP-12 (28 April–9 May 2025) adopted amendments adding chlorpyrifos, medium-chain chlorinated paraffins (MCCPs), and long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds to Annex A (elimination). COP-12 also adopted an amendment related to UV‑328 in Annex A to add an additional specific exemption. Compliance teams should evaluate product and supply-chain exposure to these newly listed POPs and track exemption conditions/availability for UV‑328 where applicable, as these COP decisions drive Parties’ national implementation measures and may affect permitted uses and phase-out timelines.
ECHA’s Weekly (7 May 2025) reports that the European Commission adopted amendments to Annex I of the EU POPs Regulation on 5 May 2025 that affect PFAS controls for firefighting foams containing PFOA, its salts and PFOA-related substances. The changes include extending the expiry date of a specific exemption for use of firefighting foams already installed in systems and setting new concentration limits for PFOA-related compounds in firefighting foam. Compliance teams in sectors using/maintaining installed firefighting foam systems (and suppliers of foam concentrates and service providers) should reassess exemption eligibility, inventory/supply constraints, and any updated concentration-limit conditions referenced by the amended Annex I requirements.
At COP‑12, Parties adopted decision SC‑12/9 amending Annex A of the Stockholm Convention to list chlorpyrifos for elimination (with the decision text setting out the listing entry and related provisions). This global listing is the upstream legal trigger that Parties implement via domestic/regional measures (e.g., import/export and production/use prohibitions, and any applicable specific exemptions). Compliance teams should monitor national implementations and verify whether any specific exemptions apply in jurisdictions where products/chemicals are placed on the market.
At COP‑12, Parties adopted decision SC‑12/10 amending Annex A of the Stockholm Convention to list medium-chain chlorinated paraffins (MCCPs) for elimination. The decision defines the MCCP scope (including C14–C17 and chlorination level criteria) and includes the Convention’s framework for any specific exemptions. Compliance teams should identify MCCP presence in substances/mixtures/articles and track jurisdiction-specific implementing measures and any time-limited exemptions relevant to their supply chains.
At COP‑12, Parties adopted decision SC‑12/12 amending Annex A of the Stockholm Convention to list long-chain perfluorocarboxylic acids (LC‑PFCAs; C9–C21), their salts and related compounds for elimination, with the decision text describing scope and specific exemptions/derogations. This listing drives downstream national/regional restrictions and trade controls. Compliance teams should map LC‑PFCA presence (including precursor/related compounds), assess any applicable specific exemptions per jurisdiction, and prepare for phase-out obligations as implemented domestically.
The POPRC-20 follow-up page compiles official Secretariat invitations for comments and information that support the POPRC technical evaluation process for potential Stockholm Convention listings and related documentation. Items highlighted in the research include (i) an invitation dated 22 January 2025 for comments on indicative lists and explanatory notes relating to long-chain PFCAs, PFOA, and PFHxS (deadline shown on the page as 9 June 2025) and (ii) an invitation dated 10 March 2025 for comments on the draft risk profile for PBDD/Fs and mixed PBCDD/Fs (deadline shown as 14 April 2025). For compliance teams, these consultations signal potential future listing actions and evolving scope/interpretation for PFAS and brominated dioxin/furan substances under the Convention process.
