4 General provisions
4.1 Dangerous goods are classified by hazard into 9 classes, and their classification and numbers shall meet the provisions of GB 6944-2025.
4.2 The Dangerous Goods List gives the most frequently transported dangerous goods, as specified in Table 1.
Note: The Dangerous Goods List does not include goods which are so dangerous that their transport, except with special authorization, is prohibited.
4.3 Each entry in the Dangerous Goods List is characterized by a UN number. The entries in the Dangerous Goods List include the following four types.
a) "Single" entries are used for well-defined substances or articles
Example 1:
UN 1090 ACETONE
UN 1194 ETHYL NITRITE SOLUTION;
b) “Generic” entries are used for a well-defined group of substances or articles
Example 2:
UN 1133 ADHESIVES, including flammable liquid
UN 1266 PERFUMERY PRODUCT, including flammable solvent
UN 2757 CARBAMATE PESTICIDE, SOLID, TOXIC
UN 3101 ORGANIC PEROXIDE, TYPE B, LIQUID;
c) Specific n.o.s. entries covering a group of substances or articles of a particular chemical or technical nature
Example 3:
UN 1477 NITRATES, INORGANIC, N.O.S.
UN 1987 ALCOHOLS, N.O.S.;

UN 1993 FLAMMABLE LIQUID, N.O.S.
4.4 Inherent instability in goods may take different dangerous forms, for example, explosion, polymerization, with intense evolution of heat, or emission of toxic gases. In respect of most dangerous substances, such tendencies can be controlled by correct packing, dilution, refrigeration, addition of an inhibitor or stabilizer, or other precautions.
4.5 Dangerous goods shall be transported as specified in the Dangerous Goods List and shall be labeled with the names suitable for the substances or articles in the Dangerous Goods List. For dangerous goods not specifically listed by name, their hazards shall be first defined, with their most appropriate proper shipping names determined, and then "generic" or "not otherwise specified" entries are provided.
4.6 Special provisions for transport by waterway, air, railway, and road shall also meet the requirements of relevant industry regulations.
5 Structure and contents
5.1 Structure and contents of the Dangerous Goods List

If a package containing a mixture is labelled with any subsidiary hazard label, one of the two technical names shown in brackets shall be the name of the constituent which compels the use of the subsidiary hazard label.
