Are all lithium batteries prohibited by mail

Not all lithium batteries are prohibited by mail, but there are specific regulations and restrictions that apply to shipping lithium batteries by air and ground.

The United States Postal Service (USPS) and the International Air Transport Association (IATA) have implemented regulations to ensure the safe transportation of lithium batteries. Here are some key guidelines:

Lithium Battery Restrictions by USPS:

  1. Prohibited: Lithium batteries with a capacity of 100 watt-hours (Wh) or more are prohibited from being shipped by USPS.
  2. Restricted: Lithium batteries with a capacity between 8-100 Wh are allowed, but only if they are properly packaged and meet specific requirements, such as:
    • Being in their original packaging or a protective case.
    • Being protected from accidental activation.
    • Being shipped via ground transportation only (not air).
  3. Permitted: Lithium batteries with a capacity of less than 8 Wh are allowed to be shipped by USPS, regardless of packaging or transportation method.

IATA Regulations:

  1. Prohibited: Lithium batteries with a capacity of 100 Wh or more are prohibited from being shipped by air.
  2. Restricted: Lithium batteries with a capacity between 8-100 Wh are allowed, but only if they are properly packaged and meet specific requirements, such as:
    • Being in their original packaging or a protective case.
    • Being protected from accidental activation.
    • Being shipped via air transportation only (not ground).

Additional Requirements:

  1. Proper Packaging: Lithium batteries must be packaged in a way that prevents accidental activation, such as being placed in a protective case or pouch.
  2. Labeling: Lithium batteries must be labeled as "Lithium Battery" and include the battery's capacity (in Wh) on the outside of the package.
  3. Shipper's Declaration: The shipper must complete a Shipper's Declaration for Dangerous Goods (SDGD) form, which includes information about the battery's capacity, type, and packaging.

It's essential to check with the USPS and IATA for the most up-to-date information on lithium battery shipping regulations, as they may change over time. Additionally, it's recommended to consult with a shipping expert or the manufacturer of the lithium battery for specific guidance on shipping their products.
