Per DOT regulations, the Class 6 Infectious Substance label and the Class 9 Miscellaneous Hazard label have been updated. Effective October 1, 2014, commercial carriers have switched to new labels. Only trained personnel are permitted to ship hazardous materials, including dry ice.
CLASS 6 INFECTIOUS SUBSTANCE LABEL
For Class 6 Infectious Substance labels, the text “In U.S.A. Notify Director-CDC, Atlanta, GA 1-800-232-0124” has been removed (see old label). The old label is no longer accepted, and the new Class 6Infectious Substance label must be affixed to packages that contain Category A infectious substances.
Refer to the hazardous material shipping training manual for the additional required markings for Category A infectious substances. If you are using dry ice, you must use the new Class 9 Miscellaneous Hazard label.
DRY ICE “CLASS 9 MISCELLANEOUS HAZARD” LABEL
For Class 9 Miscellaneous Hazard labels, the horizontal line connecting the vertical black bars has 
been removed (see old label). Both the new and old label are currently accepted, but the old label will no longer be manufactured. The Class 9 Miscellaneous Hazard label must be affixed to packages that use dry ice as a coolant or refrigerant for shipping of hazardous material packages by air, water, or ground (FedEx, UPS, DHL) transport. The US Postal Service will NOT transport dry ice.
In addition, the package must contain the following markings:
1. Class 9 Miscellaneous Hazard Label.
2. Proper shipping name and UN ID Number: “Carbon dioxide, sol-
id” or “Dry ice” and UN1845.
3. Net quantity of dry ice.
DOT also requires the font size of the UN marking to be a specific size based on the quantity of dry ice in the package. The table below will help you select the correct font size for your dry ice quantity:
Note: If using a dry ice label with a preprinted UN number, the UN number must be also handwritten.
| DRY ICE QUANTITY | “UN1845” FONT SIZE |
|---|---|
| 30kg (66lbs) | 12mm type face or larger |
| 5kg (l1 lbs) to 30 kg (66 lbs) | 6mm type face or larger |
| <5kg (11 lbs) | Be of adequate size |
