Lithium Batteries Fact Sheet


Lithium batteries can overheat and catch fire under certain conditions.  These fires can be difficult to extinguish and may produce toxic fumes.  

Anyone who offers lithium batteries to a carrier for transportation, including products packed with lithium batteries, or products containing lithium batteries, or anyone who transports them in commerce is subject to the Hazardous Materials Regulations (HMR) of the Pipeline and Hazardous Materials Safety Administration (PHMSA) within the U.S. Department of Transportation as well as any applicable state or international regulations for transporting hazardous materials. 

Common carriers, such as overnight delivery services or the U.S. Postal Service, may impose additional restrictions on lithium batteries.  For example, some overnight carriers require compliance with international air regulations, such as the International Air Transport Association (IATA) Dangerous Goods Regulations.  The U.S. Postal Service imposes its own restrictions on shipping lithium batteries domestically and through international mail.  It is important to check with your carrier to make sure you are complying with their requirements for shipping lithium batteries.
