Specially controlled hazardous chemicals are highly inherently hazardous with large circulation, which may pose a high safety risk of accidents and cause serious consequences, which need special control. According to the “Inventory of Specially Controlled Hazardous Chemicals”, hazardous chemicals can be classified as “explosive chemicals”, “toxic chemicals (including toxic gases, volatile toxic liquids, and solid highly toxic chemicals)”, “flammable gases”, and “flammable liquids”. The first edition of this inventory contains 20 specially controlled hazardous chemicals. This inventory is not applicable to reagent products essential for scientific experiments. According to the "Regulation on the Administration of Urban Gas", this inventory and special control measures are not applicable to urban gas.

Specially controlled hazardous chemicals transported by water, air, railway and pipeline shall be managed in accordance with relevant laws, administrative regulations and the provisions of the competent departments concerned, and where otherwise provided by laws, administrative regulations and rules, in accordance with their provisions.

Control measures for methanol and ethanol are limited to strengthening transportation management. The sale and purchase of ammonium nitrate shall be managed in accordance with the relevant regulations of civil explosives.

Specific control measures will be conducted from the following aspects:

Establish an information platform to implement traceability control of life-cycle information, mainly through the introduction of QR code or electronic label;
Standardize the packaging management, mainly promoting the packaging performance inspection and packaging use identification of hazardous chemicals;
Strict the access to safety production and the approval of construction projects for special controlled hazardous chemicals;
Strengthen transportation management by establishing strict waybill management and vehicle dynamic monitoring, with special prior control over the whereabouts of hazardous chemicals.
Implement stationary storage management. Specially controlled hazardous chemicals shall be stored in a specific area in the special warehouse for hazardous chemicals.
