China List of Priority Controlled Chemicals

China's "List of Priority Controlled Chemicals" is a framework under which the Ministry of Ecology and Environment (MEE) identifies and manages chemical substances posing high risks to the environment and human health, based on the "Regulations on the Environmental Risk Management of Toxic and Hazardous Chemicals." The regulation imposes strict declaration requirements, emission controls, and restrictions at each stage of manufacturing, processing, use, and import. In recent years, alongside revisions to the technical guidelines for chemical substance environmental risk assessment, the addition of covered substances and the tightening of management standards have accelerated, requiring companies across the entire supply chain to determine applicability and report to authorities in a timely manner.
