On November 1, 2019, the Japanese Ministry of Health, Labor and Welfare (MHLW), Ministry of Economy, Trade and Industry (METI) and Ministry of the Environment (MoE) issued the revised Notice on Use Confirmations Required in Application for Exemptions under CSCL [1].
In accordance with the Chemical Substance Control Law (CSCL, see ChemLinked Chempedia [2]), for new chemical substances with a release volume less than 1 ton/year across Japan (small-amount new chemical substances) or those which are confirmed as non-biodegradable and non-bio-accumulative with a release volume less than 10 tons/year across Japan (low-volume new chemical substances), only a simplified new substance notification is needed.
When applying for small-amount or low-volume exemptions, businesses are required to submit Use Confirmations as proof of the intended uses of their substances. The revised Notice provides a sample of Use Confirmations as well as information which should be specified therein.
Additionally, starting from the beginning of this year, some changes have been in place for the numbering of Use Categories under CSCL. This Notice also includes explanations on the new numbering mode, Use Categories and release factor.
