Dangerous Goods Labelling

Whenever hazardous materials are transported the contents of the container must be identified.

A complex classification system has evolved by the combined work of the United Nations (UN), the International Air Transport Association (IATA) and the International Maritime Organisation (IMO). The transport of Dangerous Goods by road and rail are similarly regulated.

uncletony wishes to stress that this guide is a 'getting acquainted' guide and NOT in any way an in-depth look at the Dangerous Goods regulations.

Do NOT attempt to transport dangerous/hazardous materials without contacting a specialist shipping agent.


Below are reproductions of many of the Dangerous Goods Labels, and a brief explanation of each Class.
For more detail on sub-divisions refer to IATA, UN and/or DOT definitions and regulations.

Class 1 Explosive Materials

Dangerous Goods label 1.1, 1.2, 1.3


Dangerous Goods label 1.4Dangerous Goods label 1.4F


Dangerous Goods label 1.5DDangerous Goods label 1.6


1.1, 1.2 or 1.3
Division 1.1 Explosives:
Consists of explosives that have a mass explosion hazard. A mass explosion is one which affects almost the entire load instantaneously.
Division 1.2 Explosives:
Consists of explosives that have a projection hazard but not a mass explosion hazard.
Division 1.3 Explosives:
Consists of explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard or, both but not a mass explosion hazard.

1.4B, 1.4C, 1.4D, 1.4E, 1.4G or 1.4S
Division 1.4 Explosives:
Consists of explosives that present a minor explosion hazard. The explosive effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire must not cause virtually instantaneous explosion of almost the entire contents of the package.

Division 1.5 Blasting Agents:
Consists of very insensitive explosives. This division is comprised of substances which have a mass explosion hazard but are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of transport

Division 1.6 Explosives:
Consists of extremely insensitive articles which do not have a mass explosive hazard. This division is comprised of articles which contain only extremely insensitive detonating substances and which demonstrate a negligible probability of accidental initiation or propagation.

Class 2 Gases

Dangerous Goods label 2.1Dangerous Goods label 2.2

Dangerous Goods label 2.3Dangerous Goods label 2.4

Flammable gas


Non-flammable, non-posionous gas

Posionous / toxic gas

Corrosive gas

Class 3 Flammable Liquid

Dangerous Goods label  3

The Flammable Liquid classification (Class 3) has three divisions which are differentiated by the flash point of liquid - the lowest temperature at which vapor of an inflammable liquid catches fire in the air when a flame is applied.


Class 4 Flammmable Solid

Dangerous Goods label 4.1
Dangerous Goods label 4.2Dangerous Goods label 4.3

Class 4 Division 1
Flammmable Solid


Class 4 Division 2
Spontaneously Combustible substances are liable to combustion, without direct application of flame or spark, due to an internal rise of temperature to the ignition point, usually caused by a slow oxidation process.


Class 4 Division 3
Dangerous When Wet substances when in contact with water will emit flammable gas.

Class 5 Oxidising Materials

Dangerous Goods label 5.1Dangerous Goods label 5.2

Class 5 Division 1
Oxidizer / Oxidizing Agent


Class 5 Division 2
Organic Peroxide

Class 6 Poison

Dangerous Goods label 6

Dangerous Goods label 6.1Dangerous Goods label 6.2

Class 6


Class 6 Division 1
Harmful to Foodstuff


Class 6 Division 2
Infectious Substance

Class Radioactive Materials

Dangerous Goods label 7-I

Dangerous Goods label 7-IIDangerous Goods label 7-III

The Radioactive non-fissile materials (Class 7) have three categories (I, II and III) determined by the radiation level of the package.



Class 7 has no divisions.

Class 7 Category I

Class 7 Category II

Class 7 Category III

Class 8 Corrosive Substances

Dangerous Goods label 8

Corrosive Substances (Class 8) will cause damage to the skin and/or metal.

Class 9 Miscellaneous

Dangerous Goods label 9

Class 9 covers miscellaneous hazardous materials not covered by other classes, for example magnetized material which poses a danger to the aircraft compass unit.
