Select the documents required to ship a Category A substance by air.

• A. Air Waybill, Shipper's Declaration, and itemized list of contents
• B. Air Waybill and packing list
• C. Shipper's Declaration and safety data sheet
• D. Shipper's Declaration only

Answer: (A)

For Category A infectious substances shipped by air, the shipment must be accompanied by documents that prove proper regulatory compliance and precise identification of the contents. The Air Waybill is essential because it is the transport contract with the airline and identifies the shipment for routing and tracking. The Shipper’s Declaration for Dangerous Goods is also required, serving as the formal certification that the dangerous goods have been properly classified, packaged, labeled, and declared in accordance with the regulations, with the necessary emergency information and quantities. In addition, an itemized list of contents is needed to provide a detailed inventory of every element inside the shipment—listing the exact substances, their containerization, and amounts—so handlers and emergency responders know exactly what is inside each package. The packing list or a Safety Data Sheet alone does not meet these regulatory requirements; the packing list doesn’t substitute for the declaration, and the SDS provides hazard information rather than the shipping documentation required for transport.
