Class 9: Other substances and articles
What is class 9 in the dangerous goods categories?

Class 9 covers substances and articles which during carriage, present a danger not covered by the heading of other classes.

Such products have properties which cannot be included elsewhere in the UN Class system, or which have a number of disconnected dangers crossing two or more Class boundaries.

The classic example of this diversity is self-inflating life rafts, which include in the package:

  • A large compressed gas cylinder, usually carbon dioxide, to inflate the raft and its canopy when it hits the water.
  • Various explosive flares, coloured smoke candles, etc., for attracting the attention of rescuing air and sea craft.
  • Flammable solid materials for heating food and providing warmth.
  • Fabric repair kits, containing flammable liquids as the base for adhesive solutions.

Moreover, some articles and substances are assigned commonly in Class 9 as following:

  • Magnetized Materials
  • Lithium Batteries
  • Life-Saving Appliance
  • Dry Ice (Carbon Dioxide, Solid)
  • Vehicle
  • Battery-powered Equipment
  • Engines
  • Consumer Commodity

As ‘Environmental’ becomes a popular topic among people and concern globally, when Substances or mixtures dangerous to the aquatic environment not presenting a danger covered by other classes, must be assigned to packing group III and designated:

UN 3077 and UN 3032: Environmentally Hazardous Substances.


UN 3077 Environmentally Hazardous Substances, Solid, n.o.s.
UN 3032: Environmentally Hazardous Substances, Liquid, n.o.s.

Environmentally hazardous substances (include aquatic environment) are those that meet the criteria of the UN Model Regulations or that meet criteria in national or international regulations established by the appropriate national authority in the State of origin, transit, or destination of the consignment. Detailed classification categories and criteria for environmentally hazardous substances are set out in the UN Model Regulations, which can be found at:
