What is the required height for the Lithium Battery Mark on shipping labels?

• A. 12 mm
• B. 20 mm
• C. 5 mm
• D. 8 mm

Answer: (A)

The key idea is ensuring the hazard mark is clearly legible on the package. The Lithium Battery Mark must be at least 12 millimeters tall on shipping labels. This minimum size makes the mark easy to read during handling and meets the standard requirements for air shipments. Markings that are only 5 or 8 millimeters tall would be too small to read reliably, so they wouldn’t comply. A 20 millimeter mark is larger than the minimum and would still be legible, but the required height (the standard minimum) is 12 millimeters.
