On 1 June 2023, the National Institute of Environmental Research (NIER) in South Korea publicly notified the Designation of Toxic Substances under the Act on Registration and Evaluation of Chemicals (K-REACH). 

Earlier this year, NIER consulted on a draft amendment for this matter, and the main proposed revisions included the following:  

• The new designation of toxic substances for which hazard assessment has been completed: CAS 2713-34-0, CAS 872-93-5, CAS 91742-16-4, CAS 79-00-5, CAS 1976005-08-9, and CAS 84988-61-4.

• Revise the name of toxic substances: DMAB; Dimethylamine borane; CAS 74-94-2, CAS 68-11-1 and mixtures containing more than 1%, CAS 126-98-7 and mixtures containing more than 1%, Selenium [CAS 7782-49-2] or its compounds and 1% a mixture containing the above. However, selenium, cadmium sulfoselenide orange (CAS 12656-57-4), cadmium sulfoselenide red (CAS 58339-34-7), except that it contains less than 25 % of CAS 10026-13-8 and mixtures containing it more than 1%, CAS 102-82-9 and mixtures containing it more than 1%, and CAS 1702310-11-9.

• Regulate newly designated toxic substances on import declaration & business license under Chemical Control Act (CCA), labeling hazardous chemicals, and transitional measures for handling.
