United Nations Committee of Experts on TDG

The Transport Dangerous Goods Directorate is a member of the United Nations Committee of Experts on the Transport of Dangerous Goods as well as its Sub-Committee.

The Committee of Experts on the Transport of Dangerous Goods meets in December of even-numbered years (e.g., December 2000, December 2002, etc.). It reviews and approves the proposed changes recommended by its Sub-committee and these approved changes are published in the UN Recommendations for the Transport of Dangerous Goods (i.e., UN Orange Book). The Orange Book is published approximately six months after the biennial Committee meetings. Currently, twenty-five countries are full voting members of the Sub-Committee.

The Sub-Committee of Experts meets in July and December of odd-numbered years (e.g., July 2001, December 2001). The Sub-Committee reviews proposals from member states for changes to the UN Recommendations for the Transport of Dangerous Goods (i.e. UN Orange Book) and makes recommendations to the Committee. The Orange Book forms the basis for TDG programs in countries and those administered through modal agencies (e.g. International Maritime Dangerous Goods Code, International Civil Aviation Organization Technical Instructions).

Proposal papers, minutes/reports of past meetings and agendas for upcoming meetings are available from the following UN TDG web site:
