South Korea: revision of the SDS Standards

Korean SDS: what’s new?

On 6^th August 2025 the Ministry of Employment and Labor (MoEL) issued the Notice No. 2025-50, updating the Standards for Classification, Labeling, and Material Safety Data Sheets of Chemical Substances

The MoEL Notice No. 2025-50 introduces some small changes to the Korean SDS, specifically in Section 15. The regulation updates the order of existing regulatory references and adds a new subheading:

1. Industrial Safety and Health Act – unchanged
2. Chemical Substances Control Act – revised
3. Act on Registration and Evaluation of Chemical Substances – newly added
4. Dangerous Material Safety Control Act – reordered (from c to d)
5. Wastes Management Act – reordered (from d to e)
6. Other domestic and international requirements – reordered (from e to f)

Within Section 15, the Chemical Substances Control Act now requires disclosure of newly classified hazardous chemicals. The former “Toxic Substances” category has been repelled and replaced with three new categories:

• Acutely hazardous substances to the human body
• Chronically hazardous substances to the human body
• Environmentally hazardous substances

Korean SDS: when?

The regulation will be effective from August 7^th, 2025, however, the SDS may still be prepared according to the previous format until June 30^th, 2026.

Trace One has planned a regulatory analysis regarding this topic and will keep you updated on it.
