Under certain conditions, the transportation of large quantities of non-bulk packages of hazardous materials requires the display of identification numbers.
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.
