The ministry reviewed these chemicals and confirmed that they met the criteria for addition to the IECSC specified by the Measures on the Environmental Management and Registration of New Chemical Substances and the Guidelines for the Environmental Management and Registration of New Chemical Substances, after companies and industry groups submitted requests for their addition.

In an announcement in June 2019, the ministry stated that companies and industry groups can request the addition of new substances to the IECSC if they have been produced in or imported into China before October 15, 2003. Many companies, including Japanese-owned firms, and industry groups have submitted this request.
