Which threshold determines the need for strong outer packaging and marking for 3091 Lithium Metal Batteries?

• A. More than 4 cells and 2 batteries per package
• B. Exactly 4 cells and 1 battery per package
• C. More than 10 cells per package
• D. Only when transported by CAO

Answer: (A)

When shipping 3091 Lithium Metal Batteries, the level of packaging required depends on how many cells or batteries are in a single package. The threshold that triggers the need for strong outer packaging and marking is when a package contains more than four cells and more than two batteries. Crossing this limit increases the risk of damage, short circuits, or thermal events, so a more robust outer container and clear markings are required to protect people and the shipment. If you stay at or below that threshold—four cells and two batteries or fewer—you don’t need the stronger outer packaging and markings mandated for larger quantities, provided all other packaging rules are met. The other options don’t fit because they either set a looser or a looser/irrelevant threshold, or they tie the requirement to transport mode rather than the quantity in the package.
