Which code corresponds to plastic receptacle with outer plywood drum?

• A. 6HB2
• B. 6HC
• C. 6HD1
• D. 6HA1

Answer: (C)

Understanding how IATA packaging codes describe the way dangerous goods are packed is key here. The code starts by naming the hazard class, then uses letters to describe the specific packaging configuration, including both the inner receptacle and the outer container. A code in this family that ends with a digit like 1 indicates a particular packing instruction for that exact configuration.

In this case, the combination describes a plastic receptacle as the inner container and an outer plywood drum as the outer packaging. The D in the code is the indicator for the wood/plywood outer drum, and the final 1 shows the standard packing instruction for this setup. That’s why this code matches a plastic receptacle inside an outer plywood drum.

The other options point to different outer packaging materials or drum types, so they don’t describe a plywood drum outer packaging.
