On July 31, 2019, the Japanese Ministry of Economy, Trade and Industry (METI), Ministry of the Environment (MOE), and Ministry of Health, Labor and Welfare (MHLW) released the Joint Notice No.2 , announcing the names, serial numbers, and MITI numbers of 210 new chemical substances under the Chemical Substance Control Law (CSCL).
Following the release, these substances will be considered as Newly Announced Chemical Substances (notified on and after April 1, 2011) and categorized as General Chemical Substances 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).
