The itemized list of contents required by Packing Instruction 650 must be placed between which two layers of packaging?

• A. Primary and secondary
• B. Outer package and the OVERPACK
• C. Secondary and outer package
• D. Absorbent material and the secondary

Answer: (C)

The itemized list of contents required by Packing Instruction 650 belongs in the space between the secondary packaging and the outer packaging. This placement keeps the inventory with the shipment and protects the list from contact with the inner contents while still allowing inspectors or handlers to view it without breaking the innermost packaging. If the list were placed inside the primary/inner packaging, it could be damaged or require opening the primary to read it. If it were placed between the outer package and an overpack, or between absorbent material and the secondary, it would be at an inappropriate location—either outside the protective envelope or in a position that could be damaged or misplaced—defeating the purpose of having a secure, accessible contents listing.
