Question 1

How much dry ice can I ship with FedEx?

Accepted Answer

FedEx allows up to 200 kg of dry ice per package for air transport per 49 CFR 173.217. All packages must display UN1845 marking, the proper shipping name, net weight in kg, and a Class 9 hazard label (minimum 100mm diamond). For air shipments, the AWB must include the dry ice description.

Question 2

Do I need a Class 9 label for ground shipments?

Accepted Answer

For FedEx and UPS ground shipments, a Class 9 label is generally not required, but UN1845 marking, proper shipping name, and net weight must still be displayed. For USPS surface mail, you need a 'Surface Only' marking instead of a Class 9 label. Always verify current requirements with your carrier.

Question 3

Can I ship dry ice internationally with USPS?

Accepted Answer

No. USPS does not accept international mail containing dry ice. For international dry ice shipments, you must use FedEx, UPS, or another carrier that supports international dangerous goods transport.

Question 4

What is the UPS 2.5 kg threshold for dry ice?

Accepted Answer

For UPS domestic air shipments with non-medical contents, packages containing more than 2.5 kg of dry ice go through an acceptance audit path with additional verification requirements. Packages with 2.5 kg or less may follow a simplified handling path, though all standard markings are still required.
