Which statement is true about the placement of orientation arrows on a Category B package?

• A. Orientation arrows are optional
• B. The itemized contents list must be between primary and secondary packaging
• C. The orientation arrows must be on opposing sides of the package
• D. There is no requirement for contact information

Answer: (C)

Orientation arrows must be placed on opposing sides of the outer packaging to show the correct upright orientation during transport. For Category B shipments (UN 3373), these arrows are required to be visible on two opposite faces so that, no matter how the package is handled or viewed, you can quickly tell which side should be kept up. This helps prevent spills or damage by keeping the contents oriented properly throughout handling, stacking, and transit.

So the statement is true because arrows are not optional in this context; they serve a safety purpose by indicating upright positioning on two opposite sides. The idea about the itemized contents list between layers is unrelated to arrow placement, and there is a separate requirement to have contact information on the packaging or accompanying documents, not about where the orientation arrows go.
