I. Definition and Determination Principles of Hazardous Chemicals
Definition

Highly toxic chemicals and other chemicals that are toxic, corrosive, explosive, flammable or combustion-supporting, and are hazardous to human health, facilities and the environment.

Determination Principles

The varieties of hazardous chemicals are determined from the following hazard and risk categories according to the national standard for chemical classification and labelling:

1. Physical Hazards
  • Explosives:Unstable explosives, 1.1, 1.2, 1.3, 1.4.
  • Flammable gases:Category 1, 2, chemically unstable gases Category A, B.
  • Aerosols:Category 1.
  • Oxidizing gases:Category 1.
  • Gases under pressure:Compressed, liquefied, refrigerated liquefied, dissolved gases.
  • Flammable liquids:Category 1, 2, 3.
  • Flammable solids:Category 1, 2.
  • Self-reactive substances:Type A~E.
  • Pyrophoric liquids/solids:Category 1.
  • Self-heating substances:Category 1, 2.
  • Substances emitting flammable gases in contact with water:Category 1, 2, 3.
  • Oxidizing liquids/solids:Category 1, 2, 3.
  • Organic peroxides:Type A~F.
  • Metal corrosives:Category 1.
2. Health Hazards
  • Acute toxicity:Category 1, 2, 3.
  • Skin corrosion/irritation:Category 1A, 1B, 1C, 2.
  • Serious eye damage/irritation:Category 1, 2A, 2B.
  • Respiratory/skin sensitization:Category 1A, 1B.
  • Germ cell mutagenicity:Category 1A, 1B, 2.
  • Carcinogenicity:Category 1A, 1B, 2.
  • Reproductive toxicity:Category 1A, 1B, 2, additional category.
  • Specific target organ toxicity (single exposure):Category 1, 2, 3.
  • Specific target organ toxicity (repeated exposure):Category 1, 2.
  • Aspiration hazard:Category 1.
3. Environmental Hazards & Others

Hazardous to the aquatic environment:

  • Acute hazard: Category 1, 2
  • Long-term hazard: Category 1, 2, 3

Hazardous to the ozone layer:Category 1

II. Definition and Thresholds of Highly Toxic Chemicals

Definition: chemicals with severe acute toxicity hazards, including synthetic chemicals and their mixtures, and natural toxins.

Threshold: Acute toxicity Category 1 (oral LD50 ≤ 5 mg/kg, dermal LD50 ≤ 50 mg/kg, etc.).

III. Notes on the Catalogue of Hazardous Chemicals
  • No.:The serial number of the chemical in the Catalogue of Hazardous Chemicals.
  • Product Name:The name determined according to the Principles of Chemical Nomenclature (1980).
  • Alias:Names other than the "product name", including common names and trivial names.
  • CAS No.:The unique registry number assigned by the Chemical Abstracts Service (CAS).
  • Remarks:Special notes for highly toxic chemicals.
IV. Other Matters
  1. The Catalogue of Hazardous Chemicals is sorted by the Hanyu Pinyin of the Chinese product name.
  2. Unless otherwise listed, inorganic salts include both anhydrous and crystalline-hydrate compounds.
  3. Entry No. 2828 is a generic entry; besides the listed entries, those meeting the corresponding conditions are hazardous chemicals.
  4. Entries without content specification (other than mixtures) refer to the industrial product or a chemical of higher purity; for pesticide use, they refer to the technical material.
  5. Pesticide entries are determined by comprehensively considering physical hazards, health hazards, environmental hazards and pesticide management.
