Which Special Provisions apply to UN 3373 Biological Substance, Category B shipments?

• A. A81
• B. A140
• C. A180
• D. None

Answer: (D)

Special Provisions are additional notes that accompany a UN shipping name to tailor packaging, labeling, and handling beyond the base rules. For UN 3373 Biological Substance, Category B, the standard packaging requirement is covered by the specific packaging instruction (PI 650), which governs how Category B materials must be packed, labeled, and documented. The provisions listed here are not associated with UN 3373 in the current regulations, so none of them apply. If there were a Special Provision for UN 3373, it would appear as a SP number elsewhere in the regulatory table (for example, SP 566 in some editions), but it isn’t one of the options given.
