HMT - Column 9

Column 9, labeled Quantity Limitations, is divided into two columns. Column 9A specifies the maximum quantities that may be offered for transportation in one package for a passenger-carrying aircraft or passenger-carrying rail car. Column 9B specifies the maximum quantities that may be offered for transportation in one package for cargo aircraft only. If the material is forbidden on passenger aircraft but permitted on cargo aircraft, it must be labeled with the Cargo Aircraft Only (CAO) label.
