Experience Everything Compliance Network Has to Offer
Each hazardous material that is offered for transport must be clearly described on the shipping paper using the applicable information from the Hazardous Materials Table.
This shipping description must include the material’s:
Example: 2 drums, UN1717, Acetyl chloride, 3, (8), II, 180 lb.
Subsidiary hazard Classes or Divisions must be included, in parentheses, when subsidiary labels are required. Unless excepted, a subsidiary label is required when indicated in Column 6 (Label Codes) of the Hazardous Materials Table, or by 172.402.
Example: UN1463, Chromium trioxide, anhydrous, 5.1, (6.1, 8), II
The total quantity is not required for hazardous material packages containing only residue (i.e., one that has not been cleaned and purged or refilled with a non-hazardous material), for cylinders, and for bulk packages. However, some indication of total quantity must be shown for cylinders and bulk packages (such as 10 cylinders or 1 cargo tank).
Examples:
The first five items — often referred to as the material’s basic description — must be shown in sequence, with no additional information interspersed unless authorized by the regulations. The identification number must include the letters “UN” or “NA” or “ID”, as appropriate. The packing group must be shown in Roman numerals and may be preceded by the letters “PG”. (172.202)
