Japan Proposes Export Controls On LC-PFCAs, Chlorpyrifos And MCCPs Under Stockholm Convention Update

Japan’s Ministry of Economy, Trade and Industry (METI) has launched a public consultation on proposed amendments to export control rules covering four additional persistent organic pollutants (POPs): long-chain perfluoroalkyl carboxylic acids (LC-PFCAs) and their salts, LC-PFCA-related substances, chlorpyrifos and medium-chain chlorinated paraffins (MCCPs). The changes follow decisions adopted at the 12th Conference of the Parties to the Stockholm Convention in April and May 2025 and are scheduled to take effect on 22 November 2026. The proposal will affect manufacturers, importers, exporters, distributors and downstream users across multiple industries.

Stockholm Convention Drives New Export Restrictions

According to METI, the Stockholm Convention requires participating countries to prohibit or restrict the export and import of chemicals listed under Annex A or Annex B because of their persistence in the environment, bioaccumulation potential and toxicity. Japan currently requires ministerial approval for exports of covered substances and is updating its framework to reflect newly listed chemicals.

The consultation covers amendments to the Export Trade Control Order and related guidance documents. Public comments are being accepted from 22 June to 22 July 2026.

LC-PFCAs, Chlorpyrifos And MCCPs Added To Controlled Chemicals

The proposed amendments add four substance groups to Japan’s export control regime:

• LC-PFCAs (carbon chain lengths C9-C21) and their salts.
• LC-PFCA-related substances.
• Chlorpyrifos, an organophosphate pesticide.
• MCCPs, defined as chlorinated straight-chain paraffins with carbon chain lengths C14-C17 and chlorine content of at least 45% by molecular weight.

METI’s draft guidance also identifies products that may fall within the scope of controls when these substances are present. Examples include lubricants, water- and oil-repellent treated textiles, paints, adhesives, sealants, firefighting products, flooring materials, waxes and photographic films for PFAS-related substances. MCCP-containing lubricants, plasticisers, coatings and textile protection products are also listed.

Compliance Implications For Industry

The proposal extends beyond chemical manufacturers. Exporters of treated textiles, coatings, industrial lubricants, construction products, electrical equipment components and agricultural chemical products may need to review formulations, supplier declarations and export classifications.

Businesses should begin assessing whether products contain LC-PFCAs, related PFAS substances, chlorpyrifos or MCCPs, particularly where international shipments are involved. Early supply chain mapping and substance verification could help minimise compliance risks ahead of the November 2026 implementation date.
