On August 30, 2024, South Korea’s National Institute of Chemical Safety (NICS) adopted the proposed updates to the Toxic Chemical Substances List (TCSL) and the GHS Classification List. The updated TCSL will come into force three months after its publication. The amendments to GHS Classification List took effect immediately.
Updates to TCSL
Ten substances are now designated as toxic chemical substances (Given No. 2024-1-1213 ~ 2024-1-1222), which were registered and found toxic after hazard evaluation under K-REACH. Their chemicals names, CAS numbers, and concentration limits in mixtures are shown below.
The chemical name and/or CAS number of two toxic chemicals (Given No. 2017-1-762 and 2022-1-1095) that were previously listed in the TCSL have been updated.
Manufacturers, importers and handlers, who have operated businesses involving the 10 new toxic substances and mixtures containing them before the effective date, shall complete relevant obligations under the Chemical Control Act (K-CCA) within the deadlines specified. More specifically,
By July 1, 2025
Manufactures or importers shall submit a ‘Written Confirmation of Verification on Chemical Products’ as per Article 9 of K-CCA.
Handlers shall complete updating the labels of these toxic substances as per Article 16 of K-CCA.
