Category A Infectious substances may be transported as exceptions to the regulations, provided they are shipped in quantities less than:

• A. There are no exceptions for Division 6.2
• B. 0.5 mL
• C. 1 mL
• D. 30 mL

Answer: (A)

Category A infectious substances are subject to the strictest shipping requirements regardless of amount. There is no quantity-based exemption for Division 6.2 Category A, so even a tiny shipment must meet the full packaging, labeling, and documentation rules. That’s why the statement that there are no exceptions for Division 6.2 is the best answer. The other numbers imply a volume threshold that doesn’t exist for Category A; the regulations don’t provide a small-quantity exemption for these substances.
