Regulations are based on the United Nations Model Regulations on the Transport of Dangerous Goods. The most important regulations can be summarized as follows:

1. C- and D-size cells as well as larger cells and most battery packs have to be transported under dangerous goods regulations.
    
2. Lithium batteries below 2 g lithium content (corresponding approximately to 3 AA cells) are exempted from dangerous goods regulations but each package requires a special label to indicate that it contains lithium batteries and special procedures shall be followed when a package is damaged during transportation.
    
3. Transport regulations require that lithium cells and batteries of all kinds, exempted or not, be tested according to the UN test methods.

Packing instructions for air transport of lithium batteries worldwide have changed as of January 2009. Changes are more significant for bulk transport of lithium batteries than for lithium batteries packed with or contained in equipment. According to the new regulations, Tadiran Lithium Batteries are classified as lithium metal batteries. Different regulations are valid for transport in the USA.
