Taiwan to Ban Methoxychlor, Dechlorane Plus, and UV-328, Effective July 1, 2026

On April 27, 2026, Taiwan's Ministry of Environment (MOENV) announced amendments to the Categories and Management of Handling for Toxic Chemical Substances, a subsidiary regulation under the Toxic and Concerned Chemical Substances Control Act (TCCSCA). Effective July 1, 2026, the amendments designate methoxychlor, dechlorane plus, and UV-328 as toxic chemical substances, aligning with the Stockholm Convention, as they are listed in Annex A as industrial POPs targeted for global phase-outs. The amendments also tighten controls on existing regulated toxic chemical substances, including mercury and tetrachloroethylene.
