What dry ice information is required on the waybill when it is shipped with a Category B infectious substance?

• A. Class or division
• B. UN number
• C. Proper shipping name
• D. All of the above

Answer: (D)

The key idea is that dry ice must be clearly identified as a hazardous material on the waybill, even when it’s used to keep a Category B infectious substance cold. Dry ice is Class 9 (miscellaneous dangerous goods), so the waybill must show its class or division. It also needs the UN number that identifies the substance, which for dry ice is UN 1845. Finally, the waybill should include the proper shipping name for the item, typically “Dry Ice” (or “Carbon dioxide, solid”). Together, these three pieces of information remove any ambiguity about what is in the shipment and how it should be handled during transport. Since the infectious substance itself has its own entry (UN 3373, Infectious substance, Category B) and must be listed separately, including all three dry ice details ensures the entire shipment is clearly and correctly documented.
