On July 31, 2020, the Japanese Ministry of Health, Labor and Welfare (MHLW), Ministry of Economy, Trade and Industry (METI) and Ministry of the Environment (MOE) jointly gazette a total of 226 new chemical substances (No. 706-No. 931) [1] under the Chemical Substance Control Law (CSCL).
Since the publication of the gazette, these substances will be considered as Newly Announced Chemical Substances (notified on and after April 1, 2011) and regulated as existing chemicals under the framework of CSCL.
Japan has two systems for new chemical substance notification, one under the CSCL framework and the other subject to the Industrial Safety and Health Law (ISHL). Substances in the two notification systems are managed separately, which certainly overlap a lot. New chemical substances which have been registered as per the ISHL will be published four times each year (in March, June, September, and December, respectively); while those registered under the CSCL are published only once a year (usually in each July).
