Japan Released 2025 Notification Schedule for Low and Small Volume New Chemical Substances

The Ministry of Economy, Trade and Industry (METI), the Ministry of the Environment (MOE), and the Ministry of Health, Labour and Welfare (MHLW) in Japan jointly released the 2025 notification schedule for the production and import of low volume and small volume new chemical substances.

Under the Chemical Substances Control Law (CSCL), enterprises must report new chemical substances based on annual production or import volume. Substances with an annual production or import volume of less than 1 ton require small volume notification, while those produced or imported from 1 ton to 10 tons require low volume notification.
