Dry ice is a great choice for keeping small shipments cold or frozen. However, dry ice falls under dangerous goods regulations, so it is critical to package these shipments correctly.

Ground shipments containing dry ice are exempt from the regulations and are not required to be marked, labelled or documented when there are no other dangerous goods in the package.

Air shipments containing dry ice can be declared online or by using the Purolator E-Ship®Server by choosing Dry Ice UN1845 from the menu.

Shipping requirements:

  Air Shipments
  • Package must be vented to allow for the release of carbon dioxide gas.
  • If a corrugated box is used as a shipping container, it should be of heavy gauge.
  • Void spaces in container should be filled with inert fill material.
