Which of the following is true about UN 3481?

• A. It applies to lithium ion batteries that are not in devices
• B. It applies to lithium ion cells or batteries contained in or packed with equipment
• C. It applies only to primary cells
• D. It applies only to small quantities

Answer: (B)

UN 3481 covers lithium ion batteries when they are not shipped alone but are part of or shipped with other equipment. The regulation applies to batteries that are contained in equipment (installed inside a device) or packed with equipment (shipped together with other gear). This distinction is what makes this option correct: it precisely describes lithium ion cells or batteries that are contained in or packed with equipment. It does not apply to batteries that are not in devices (that would be UN 3480), it isn’t limited to primary (non-rechargeable) cells, and it isn’t restricted to only small quantities—the rules cover various quantities depending on the specific packaging and mode of transport.
