Taiwan Updates Toxic Chemical Regulations with DDT, Declone & UV-328
Taiwan’s Ministry of Environment has officially updated its Toxic Chemical Substances List, adding DDT, decachlorotricyclooctadecadiene (Declone), and UV-328. The revisions also tighten regulations on mercury and tetrachloroethylene to align with the Stockholm and Minamata Conventions.
Newly Added Chemicals and Restrictions
• DDT: Now classified as Class I, III, and IV toxic chemical, with strict limits on production, import, handling, and use due to its bioaccumulative and ecotoxic properties.
• Declone (Denclofen): Listed as Class I and IV, with controlled concentration of 0.1%. Usage is prohibited except for research, testing, or education.
• UV-328: Added as Class I and IV toxic chemical, with no allowable concentration for general use. Thresholds follow EU Persistent Organic Pollutants Regulations.
• Mercury: Existing Class I toxic chemical, with updated prohibited activities and permitted uses reflecting the Minamata Convention.
• Tetrachloroethylene: Existing Class I/II chemical, with new restrictions prohibiting use in cleaning agents. Registered users may continue only until remaining material is fully recovered.
Compliance Timeline and Industry Impact
The Ministry has provided a 1 to 1.5-year transition period for existing operators. Businesses must update permits, registration, labeling, storage, detection systems, and personnel qualifications. Adoption of safer substitutes is encouraged to reduce environmental and human health risks.
With these updates, Taiwan strengthens its chemical management system, ensuring alignment with international environmental standards.
