Japanese ministries publish mixture notification rules and adds 257 chemicals to annual listing

Rules for mixture notification published by ministries

Draft notification rules for mixtures and complex substances such as UVCBs were published by Japanese ministries on 17th July, 2018. The consultation periods of the draft ended on 15th August. If approved, the rules will take effect from April 2019 and will apply to existing general chemical substances and priority assessment chemical substances (PACs).

According to the Chemical Substance Control Law (CSCL), existing general substances or PACs manufactured/imported at more than 1t/y must be notified every April. The new rule will require a single submission for mixtures and UVCBs, which will replace the current system of submitting separate notifications.
