Explosive precursors are certain chemicals which can be used in the illicit manufacture of explosives. Those chemicals need to be controlled to reduce the risks of misuse by terrorists and protect public security.
In China, explosives precursors are mainly regulated by the State Council Decree 591 Regulations on Safe Management of Hazardous Chemicals. This regulation establishes a much tighter regulatory regime for explosives precursors than regular hazardous chemicals and sets additional requirements on the storage, purchase and sales of explosives precursors.
The Ministry of Public Security (MPS), the principle police authority in China, maintains a Catalogue of Controlled Explosives Precursors in China. The Catalogue is a small portion of the Catalogue of Hazardous Chemicals (2015) and includes 71 types of controlled chemicals, many of which are commonly used by both industrial companies and research institutions. Examples of such precursors include nitric acid (>=70%), sodium nitrate, sulfur, dihydrogen dioxide, and potassium permanganate.
The latest Catalogue was issued by MPS in 2011. You can search the Catalogue by Chinese name, English name or CAS number.
It shall be noted that the Catalogue includes several generic entries: NITROBENZENES, NITRONAPHTHALENES, NITROPHENOLS (O-,M-,P-), and NITROANILINES.
Since explosives precursors are also hazardous chemicals included in the Catalogue of Hazardous Chemicals, they are subject to production/operation/safe use license requirements and HazChem registration requirements under Decree 591. In addition to that, they are subject to additional security and reporting requirements on storage, sales and purchase. Here we will only summarize the extra requirements for explosives precursors:
