Dry ice can sometimes be used without restriction with certain carriers as long as surface shipping methods are used and the package is clearly marked for ground transit only.

For other carriers, you may need to specify the exact weight of dry ice.

A shipper’s declaration and a Class 9 DOT warning label are not required for dry ice sent via domestic surface mail. But, you will need to appropriately package and label the package. See the link for more details.

SKULabs allows you to provide the dry ice weight to shipping carriers connected through EasyPost. Create a shipping rule using the "Set dry ice weight" option and provide a default dry ice weight, which will be auto-populated on ship window dry ice weight section.

Note that the UN1845 label is required on the package according to federal hazardous material transportation requirements.

Here is where you can find additional information on shipping dry ice.
