With this amendment, items containing Dechlorane Plus or UV-328 are no longer included in these general exemptions, making it clear that they are subject to specific regulatory controls unless explicitly exempted.

Amendment to Hazardous Substances Regulations

Also on March 21, 2025, Singapore introduced the Environmental Protection and Management (Hazardous Substances) (Amendment No. 2) Regulations 2025, which took effect on March 24, 2025.

EnviX Comment
Singapore has taken a measured and structured approach to regulating Dechlorane Plus and UV-328, with key milestones as follows:

• May 31, 2022: Substances brought under regulatory scope
  
  
• May 6, 2024: Announcement of delayed implementation
  
  
• November 12, 2024: Notification of exempted uses

The latest order formally enacts the exemptions announced in November 2024, with only minor adjustments. Notably, the amendments to Appendix 2, Part 2 are newly introduced through this order, providing further clarity on the specific products subject to regulation.
