Which code corresponds to Composite Packaging with a plastic receptacle with outer aluminum drum?

• A. 6HB2
• B. 6HA2
• C. 6HB1
• D. 6HD1

Answer: (C)

This question tests how the IATA/DGR packaging code encodes the combination of inner receptacle and outer container for composite packaging. For a plastic inner receptacle inside an outer aluminum drum, the code that represents this specific configuration is 6HB1. The "6H" portion flags composite packaging, while the "HB" portion identifies the exact inner/outer combination, and the trailing "1" denotes the particular size/variant of that configuration. The other codes would indicate different inner materials or outer drum materials or a different size variant, so they don’t match the described packaging.
