Shipping Hazardous Materials

The U.S. Department of Transportation (US DOT) requires you be trained and certified before shipping hazardous materials. Even if someone else handles your shipment for you, you are responsible for packaging and labeling hazardous materials correctly, and providing the required documentation. Fines for non-compliance and potential legal action can occur if you are found to have willfully ignored hazardous materials shipping regulations.

As of July 28, 2023, EH&S is no longer responsible for reporting UW shipments of “chemicals of interest” to the U.S. Department of Homeland Security. Warning labels are no longer required for shipping chemicals of interest.


Environmental Health & Safety (EH&S) provides online and classroom training courses for UW personnel who ship hazardous materials (refer to the Training section below).

We also ship radioactive material; contact EH&S's Radiation Safety team for more information.

International shipments may also be subject to import/export requirements. Information on these requirements and contact information can be found on the UW’s Export Controls website.
