On August 11, 2025, the Chinese Ministry of Ecology and Environment (MEE) opened a public consultation on adding 4 substances to the Inventory of Existing Chemical Substances of China (IECSC). Comments are welcome before August 22, 2025.
The CAS numbers of these 4 chemical substances are:
2182-55-0
82727-34-2
211107-84-5
3065587-79-0
Details of these substances can be accessed here, including chemical name (both in Chinese and English), CAS number or Series number, molecular formula, structural formula, etc. These 4 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 proposed to be regulated as existing chemical substances in China, and thus are free from new chemical registration or notification requirements under the MEE Order No. 12.
The last update to the IECSC was made on 6 May 2025, adding 44 chemical substances to the IECSC and modifying permitted uses of 2 existing chemical substances (CL news).
