Large quantities of non-bulk packages

Scope

Typically, non-bulk packages on a transport vehicle or freight container do not require the identification number markings. However, when large quantities of non-bulk packages of certain hazardous materials are being transported, the identification number marking is required.

Summary of requirements

A transport vehicle or freight container containing only a single hazardous material in non-bulk packages must be marked, on each side and each end with the material’s identification number, and is subject to the following:

• Each package must be marked with the same proper shipping name and identification number;
• The aggregate gross weight of the hazardous material is 4,000 kg (8,820 pounds) or more;
• All of the hazardous material is loaded at one loading facility; and
• The transport vehicle or freight container contains no other material, hazardous or otherwise.

The identification number marking requirement does not apply to Class 1, Class 7, or to non-bulk packagings for which identification numbers are not required.
