Which information must appear on shipping papers for air transport?

The requirement for the UN Identification Number to appear on shipping papers for air transport is rooted in international regulations that govern the transport of dangerous goods. The UN Identification Number is a four-digit code that specifically identifies hazardous materials and helps ensure the safe transportation of such goods. This identifier enables those involved in the shipping and handling processes, including airline personnel and emergency responders, to recognize the potential hazards associated with the cargo quickly.

Having the UN Identification Number clearly marked on shipping documents enhances the efficiency of safety measures and compliance with regulations laid out by agencies like the International Air Transport Association (IATA) and the United Nations. By ensuring that this information is present, it helps facilitate the proper handling, storage, and transport of hazardous materials, thereby reducing the risk of accidents during air transport.

Other information such as the emergency contact name, shipper's declaration number, and company tax ID are relevant for various logistical and administrative purposes, but they do not hold the same critical importance in terms of immediate hazard identification and regulatory compliance as the UN Identification Number does. Therefore, it stands out as a crucial element on shipping papers for air transport.
