On December 18, 2023, China's Ministry of Ecological Environment (MEE) announced the addition of a batch of 4 registered substances that fulfill the requirements of existing substances into the Inventory of Existing Chemical Substances in China (IECSC). Earlier on October 10, 2023, these four substances are released for public consultations.
CIRS warmly reminds you that related enterprises must make sure whether their substances are existing substances. The Provisions on Environmental Administration of New Chemical Substances (MEE Order 12) require enterprises to complete new substance registration/record before manufacturing or importing, or they may face various punishments.
To find out whether your substance is listed in IECSC, please search CIRS's free ChemRadar.
