Which label set would be considered correct for a Category B package?

• A. UN 3373 Diamond-on-point marking
• B. Dry ice label
• C. Class 6 hazard label
• D. None of the above

Answer: (A)

For a Category B package, the identifying label is the UN 3373 mark, shown as a diamond-shaped label (square on point). This label specifically communicates that the contents are a Biological Substance, Category B, and it tells handlers and regulators what kind of packaging, containment, and shipping requirements apply. The dry ice label only becomes necessary if dry ice is used as a refrigerant inside the package, not as a general requirement for Category B labeling. The Class 6 hazard label is for toxic substances and does not apply to infectious substances under Category B. So the UN 3373 diamond-on-point marking is the correct labeling set for Category B.
