On March 7, 2025, Taiwan’s Ministry of Labor (MoL) announced proposed changes to the regulations for the registration of new chemical substances. A draft version of the updated regulation is now open for public comment. The deadline for submitting comments is 60 days from March 7, 2025.

Current Regulatory Framework

Currently, there are two separate regulatory systems for registering new chemicals: one under the Ministry of Labor (MoL) and another under the Ministry of Environment (MoEnv). Since much of the required data overlaps, the MoL plans to revise its regulation to reduce duplication and make the process more efficient.

Key Proposed Changes

• Mutual Recognition of Registrations: If a company has already registered a new chemical with the MoEnv, it will no longer need to re-register the same substance with the MoL.
• Updated Legal Terminology: The name of the law has been updated from Toxic Chemical Substances Control Act to Toxic and Concerned Chemical Substances Control Act.
• Removal of Obsolete Transitional Provisions: Two transitional provisions related to older substances are being removed, as their deadlines have already passed.

Companies will still be required to submit core information, including:

• Identification of the chemical
• Details on how it is manufactured and used
• Hazard and safety data
• Toxicological information
• Environmental impact data
