On March 3, 2022, the Chinese Ministry of Ecology and Environment (MEE) published a notice, announcing the addition of 18 substances into the Inventory of Existing Chemical Substances (IECSC). These substances were previously registered under the Measures on Environmental Management of New Chemical Substances (MEP Order No. 7 of 2010), and now are qualified for listing into the IECSC as existing chemical substances in China. Details of these substances can be accessed here, including chemical name (both in Chinese and English), CAS number or Serial number, molecular formula, and permitted uses (if subject to new usage environmental management). They are now regulated as existing chemical substances in China, and thus free from new chemical registration or notification requirements under the Measures for the Environmental Management Registration of New Chemical Substances (MEE Order No. 12). However, if the substance is used for industrial applications other than the permitted uses, new usage registration will be required.
