ILO is a specialized agency of the United Nations



Compiled from the European Agreement concerning the international carriage of dangerous goods by road (ADR).

The lists of goods and substances in different classes presented below are not comprehensive.

Transport units carrying dangerous goods in quantities above the values indicated should be supervised or, alternatively, may be parked unsupervised in an isolated location in the open at a secure depot or factory premises.
