Recently, the National Institute of Environmental Sciences (NIER) of South Korea issued Announcement No. 2023-26 to update the list of hazardous substances and solicit industry opinions. This announcement will be officially implemented three months after its release.

According to the Chemical Substance Registration and Evaluation Act (K-REACH), South Korea conducts a hazard review and assessment of substances that have completed registration, and classifies substances based on the results of the substance review. If it is a toxic substance, NIER will include it in the list of toxic substances and issue an announcement.

This announcement has added 6 toxic chemicals, as shown in the table below:

Substance number	Substance name and content requirements
2023-1-1110	[3,5-Difluorophenol;2713-34-0] and its mixtures with content above 5%
2023-1-1111	[Tetrahydro-3-methylthiophene 1,1-dioxide; 872-93-5] and its mixtures with content above 25%
2023-1-1112	[1,1,1-Trifluoro-N-[(trifluoromethyl)sulfonyl]methanesulfonamide, cesium salt (1:1); 91742-16-4] and its mixtures with content above 25%
