On May 6, 2025, the Chinese Ministry of Ecology and Environment (MEE) announced the addition of 44 chemical substances to the Inventory of Existing Chemical Substances in China (IECSC), and the modification of the permitted uses of 2 previously listed existing chemical substances.
Among the 44 chemical substances, 7 substances were manufactured in or imported into China before October 15, 2003, which fulfilled the supplementation criteria but missed the previous supplementation window. They are now regulated as existing chemical substances in China, and thus free from new chemical registration or notification requirements under the MEE Order No.12.
The other 37 substances are previously registered under the Measures on Environmental Management of New Chemical Substances (MEP Order No. 7 of 2010), are now qualified for listing in the IECSC as existing chemical substances in China. They are now regulated as existing chemical substances in China, and thus free from new chemical registration or notification requirements under the MEE Order No.12. However, some of these newly designated existing chemical substances are only permitted for the uses specified in the IECSC. If the substance is used for industrial applications other than the permitted uses, new usage registration will be required. Details of the 37 substances are available here.
Besides, the permitted uses of these 2 already listed existing chemical substances in IECSC are modified as follows.
Chemical name | Permitted uses | |
Previous | Now | |
Imidazolium, dialkyl-, branched alkylbenzenesulfonates | Antistatic agents in thermoplastic resins for polyethylene films | Antistatic agents for resins |
Dialkyl phosphate metal salt | Automotive engine oil lubricant additives | Automotive engine oil lubricant additives, gas engine oil lubricant additive |
The last update to the IECSC was made on 25 November 2024, adding 36 substances (CL news).
