Capital Letter D indicates the packaging material is which?

• A. Natural Wood
• B. Fiberboard
• C. Aluminum
• D. Plywood

Answer: (D)

In this packaging coding system, a single symbol identifies the outer packaging material. The symbol shown corresponds to plywood, so the material used for the packaging is plywood. This matters because plywood provides the right balance of strength and light weight for transport packaging, and it follows the required standards for wood packaging used in air shipments (including any treatment or certification requirements). Other materials would be indicated by different symbols, which is why they wouldn’t match the symbol in question.
