Which of the following is NOT correct about dry ice packaging?

• A. Temperature control label
• B. UN1845 mark
• C. Net weight kg
• D. Class 9 label

Answer: (A)

Dry ice packaging is treated as Class 9 (Miscellaneous Dangerous Goods) and uses the UN number UN1845. The markings you must see on the package include the UN1845 mark (identifying dry ice), the appropriate Class 9 hazard label on the outer packaging, and a clear indication of the net weight of the dry ice in kilograms. A separate temperature control label is not a standard requirement for dry ice shipments because the cooling effect is provided by the dry ice itself, so there’s no extra temperature-control marking mandated specifically for these packages. Therefore, the item describing a temperature control label is not a required element for dry ice packaging. The other markings—UN1845, Class 9 label, and net weight in kg—are the components that are indeed required.
