Changes to hazardous material shipping regulations in 2024


The International Air Transport Association (IATA) published regulation changes for 2024, which may impact University units and departments that ship dangerous goods by air.

If you ship hazardous materials

There are only two significant changes to the regulations for 2024:

  1. Packing Instructions 952 (Battery Powered Equipment/vehicle) – revised to include references to “equipment.”
  2. Packing Instruction 954 (Dry Ice) – revised to clarify that where packages containing dry ice are placed into an overpack, the total net quantity of dry ice in the overpack must be marked on the outside of the overpack.

There are several “impending changes” due to come into effect as of January 1, 2025, regarding lithium batteries and Category A substances. Please contact the EH&S Environmental Programs office at for more details about the upcoming changes.

If you ship radioactive materials

There are some rule changes for 2024:

  1. An additional example of the description for the first sequence of information on the Shipper’s Declaration has been added to address where a radioactive material has a subsidiary hazard, and the proper shipping name must be supplemented by the technical or chemical name.
  2. Two new examples have been added to show how radioactive materials with a subsidiary hazard should be described and how packages in an overpack should be shown.

Lastly, there are some “impending changes” due to come into effect as of January 1, 2025, regarding radioactive materials. Please contact EH&S Radiation Safety at if you have questions about the upcoming changes.
