Japan Aligns Chemical Laws with Global Standards
Japan has amended its Chemical Substances Control Law (CSCL) by designating three chemicals as Class I Specified Chemical Substances, effectively banning their use in manufacturing, import, and applications. The move aligns Japan’s chemical regulations with international standards, particularly the Stockholm Convention on Persistent Organic Pollutants, which called for their elimination in May 2023.
Japan Banned Substances and Effective Dates
The newly restricted chemicals and their enforcement dates are as follows:
|
Prohibited Products
Following the enforcement, products containing UV-328 and Dechlorane Plus will no longer be permitted for import.
Products Containing UV-328
• Lubricating oils
• Prepared additives for UV absorbers in plastics
• Paints and varnish
• Adhesives, tape, and sealing fillers
Products Containing Dechlorane Plus
• Lubricating oils
• Prepared additives for flame retardant resins
• Electronic and electrical equipment parts
• Silicon rubber
• Adhesives and tape
Scope of the Ban
The restrictions apply to all applications involving the manufacture, import, or use of these chemicals and any products containing them—except where exemptions apply.
Exemption for Defense Applications
An exception has been made for Dechlorane Plus, which may still be used in the manufacture of heat insulation materials for specific defense-related applications. However, this exemption is only valid until February 26, 2030.
Japan’s regulatory update reinforces the country’s commitment to environmental protection and public health, in line with international efforts to eliminate harmful persistent organic pollutants.
