This standard is the Part 1 of GB 30000 Rules for classification and labelling of chemicals. The structure of GB 30000 is as follows:  

—— Part 1: General rules; 

—— Part 2: Explosives; 

—— Part 3: Flammable gases; 

—— Part 4: Aerosols; 

—— Part 5: Oxidizing gases; 

—— Part 6: Gases under pressure; 

—— Part 7: Flammable liquids; 

—— Part 8: Flammable solids; 

—— Part 9: Self-reactive substances and mixtures; 

—— Part 10: Pyrophoric liquids;

—— Part 11: Pyrophoric solids; 

—— Part 12: Self-heating substances and mixtures; 

—— Part 13: Substances and mixtures which, in contact with water, emit flammable gases; 

—— Part 14: Oxidizing liquids; 

—— Part 15: Oxidizing solids; 

—— Part 16: Organic peroxides; 

—— Part 17: Corrosive to metals; 

—— Part 18: Acute toxicity; 

—— Part 19: Skin corrosion/irritation; 

—— Part 20: Serious eye damage/eye irritation; 

—— Part 21: Respiratory or skin sensitization; 

—— Part 22: Germ cell mutagenicity; 

—— Part 23: Carcinogenicity; 

—— Part 24: Reproductive toxicity; 

—— Part 25: Specific target organ toxicity - Single exposure; 

—— Part 26: Specific target organ toxicity - Repeated exposure; 

—— Part 27: Aspiration hazard; 

—— Part 28: Hazardous to the aquatic environment; 

—— Part 29: Hazardous to the ozone layer; 

—— Part 30: Desensitized explosives. 

This standard is consistent with the relevant technical content of the United Nations “Globally Harmonized System of Classification and Labelling of Chemicals, GHS” (Rev.8).

This standard shall replace the GB 13690-2009 General rule for classification and hazard communication of chemicals.
