Select the items required on the outer packaging of a sample transported on dry ice.

• A. UN1845 mark
• B. Net weight in kilograms (kg)
• C. Class 9 Miscellaneous Dangerous Goods label
• D. All of the above

Answer: (D)

When shipping a sample with dry ice, you’re handling a Class 9 dangerous good, so the outer packaging must clearly convey the identity, hazard, and quantity. The UN number marking UN1845 identifies carbon dioxide, solid (dry ice) and is required so anyone handling the package knows exactly what it is. The net quantity in kilograms shows how much dry ice is present, which affects packing requirements and transport limits. The Class 9 Miscellaneous Dangerous Goods label signals the hazard class to loaders, shippers, and authorities. Because each of these elements provides essential information for safe handling and regulatory compliance, all of them must appear on the outer packaging.
