What is the code for a steel drum with a removable head?

• A. 3A1
• B. 1A2
• C. 1A1
• D. 1N1

Answer: (B)

Understanding drum packaging codes helps you know the exact type of container just from the code. For steel drums, the code structure includes a letter that indicates the material and a final digit that shows the head type. The final digit tells you whether the drum has a removable head: a terminal 2 means the head is removable (an open-head drum), while a terminal 1 means the head is not removable (a tight-head drum).

So a steel drum with a removable head is coded as 1A2. The 1A part flags a steel drum, and the 2 at the end indicates the head is removable. The other codes are different configurations or materials (for example, a steel drum with a fixed head or a different drum category), so they don’t describe a steel drum with a removable head.
