Why can't you mail lithium batteries

Lithium batteries are not allowed to be mailed through the United States Postal Service (USPS) or other carriers due to safety concerns. Here are some reasons why:

  1. Fire risk: Lithium batteries can overheat, ignite, or even explode if damaged, punctured, or exposed to extreme temperatures during shipping. This can cause a fire or explosion, which can damage packages, buildings, and even harm people.
  2. Chemical leakage: Lithium batteries contain flammable electrolytes that can leak or spill during shipping, causing a fire or explosion hazard.
  3. Electrical shock: Lithium batteries can short circuit or become damaged during shipping, causing electrical shock or even electrocution.
  4. Regulatory restrictions: The USPS and other carriers have strict regulations regarding the transportation of hazardous materials, including lithium batteries. These regulations are in place to protect people, property, and the environment.
  5. International agreements: The International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA) have established guidelines for the transportation of lithium batteries by air, which are designed to minimize the risk of fires and other safety issues.

To ensure public safety, the USPS and other carriers have implemented the following restrictions:

If you need to ship lithium batteries, you should contact a carrier that specializes in shipping hazardous materials, such as UPS or FedEx, and follow their specific guidelines and regulations.
