Chemical weapons precursors are certain toxic chemicals and their precursors which can be used in the illicit manufacture of chemical weapons. Examples of such chemicals include sodium cyanide, phosgene and many organic compounds containing the elements Phosphorus, Sulphur or Flourine. In China, those chemical weapons precursors are called controlled chemicals.
China has ratified the Chemical Weapons Convention (CWC) since 1997 and imposed strict license and declaration obligations on companies who produce, trade, use, import and export controlled chemicals.
In China, controlled chemicals are mainly regulated by the following administrative regulations and department rules:
The National CWC Implementation Office, which is under the Ministry of Industry and Information Technology (MIIT), is leading the administration of controlled chemicals.
In China, controlled chemicals are listed on different schedules and subject to different regulatory requirements:
Discrete organic chemical is defined as any chemical belonging to the class of chemical compounds consisting of all compounds of carbon except for its oxides, sulfides and metal carbonates, identifiable by chemical name, by structural formula, if known, and by Chemical Abstracts Service (CAS) registry number, if assigned.
PSF chemical is defined as an unscheduled discrete organic chemicals containing one or more elements phosphorus, sulfur or fluorine. Producing PSF chemical in China is subject to additional license requirement.

It shall be noted that if one controlled chemical is also a hazardous chemical, it has to comply with the requirements of Decree 591 Regulations on Safe Management of Hazardous Chemicals;.
