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

• A. 6HA1
• B. 6HD1
• C. 6HB1
• D. 6HB2

Answer: (C)

The concept being tested is how UN packaging codes identify the type of packaging. A code that starts with the 6H indicates a composite packaging, meaning there is a plastic inner receptacle inside an outer container. The next letter specifies the material of the outer drum, and the final digit marks the design level.

In this case, the configuration described is a plastic inner receptacle with an outer aluminum drum. That combination is represented by the HB portion, with the 1 indicating the standard design. So the code that matches this setup is the one with HB1. The other codes would point to different outer materials or different design variants, which don’t fit the specified configuration.
