For the pilot project K-REACH adds ten chemical substances

24 Jan 2022

The Ministry of Environment designated chemical substances with risk concern as substances subject to authorization. It introduced the system for designation and management of substances subject to authorization in 2015. Any person who wants to manufacture, import or use the relevant substances should get authorization from the Minister of Environment. Korea.

Candidate substance list and the risk assessment results

According to the Article 19 and 25 of K-REACH (Act on Registration and Evaluation, Etc. of Chemical Substances), the Minister of Environment shall designate substances subject to intensive Priority control substances and other chemicals with risk concern as substances subject to authorization and make announcement, and the person who wants to manufacture, import, and use a substance subject to authorization shall prepare, submit materials regarding its use, risk and alternative analysis, and get authorization.

For the pilot project, below ten chemical substances are selected as candidate substances. These chemicals fall under the category of CMR(Carcinogenicity, Mutagenicity, Reproductive toxicity), PBT(Persistent·Bioaccumulative·Toxic) or endocrine disruptors.
