On June 2, 2023, China's Ministry of Ecological Environment (MEE) announced the addition of a batch of four substances that fulfill the requirements of existing substances for inclusion in the IECSC.
Following its review of the application materials and evidence documents submitted by the applicant, the MEE believed that these substances fulfill the requirements for IECSC supplementation.
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.
