International Civil Aviation Organization Technical Instructions

The International Civil Aviation Organization (ICAO) has responsibility for all aspects of international civil aviation. It develops standards and recommended practices through the development of Annexes to the 1944 Convention on International Civil Aviation. In 1981, the ICAO adopted Annex 18 covering the air transport of dangerous goods and, in addition, published a set of Technical Instructions detailing the requirements for these transports. The Technical Instructions contain a list of dangerous goods, as well as requirements for packing, marking, labelling and documentation fully consistent with the IAEA Regulations.


The International Air Transport Association (IATA), a trade association representing airlines, publishes annually the Dangerous Goods Regulations (DGR) which are consistent with the ICAO Technical Instructions as well as the IAEA Regulations.

Universal Postal Convention

Transport of radioactive material by post is regulated by the Universal Postal Convention and its detailed regulations, published by the Universal Postal Union. The Convention allows the transport of exempted quantities of radioactive materials, within the meaning of the IAEA Regulations, and must conform to IAEA prescriptions.
