Can lithium ion batteries be mailed domestically

In the United States, the shipping of lithium-ion batteries is regulated by the Pipeline and Hazardous Materials Safety Administration (PHMSA) and the United States Postal Service (USPS).

According to the PHMSA, lithium-ion batteries are considered hazardous materials and are subject to specific regulations when shipped by air or ground. The regulations vary depending on the type of battery, its capacity, and the shipping method.

For domestic shipping, the USPS has specific guidelines for shipping lithium-ion batteries:

  1. Prohibited items: Lithium-ion batteries with capacities above 100 watt-hours (Wh) are prohibited from being shipped by USPS.
  2. Permitted items: Lithium-ion batteries with capacities 100 Wh or less are allowed to be shipped by USPS, but they must be properly packaged and labeled.
  3. Packaging requirements: Batteries must be packaged in a protective case or pouch to prevent damage and short circuits.
  4. Labeling requirements: Batteries must be labeled as "Lithium Ion Batteries" and include the following information:
    • The type of battery (e.g., lithium-ion)
    • The capacity (in watt-hours)
    • The manufacturer's name and address
  5. Shipping restrictions: Lithium-ion batteries can only be shipped by ground transportation (not air) and must be shipped via a USPS-approved carrier.

To ensure compliance with these regulations, it's recommended to:

  1. Check with the USPS for specific guidelines and restrictions on shipping lithium-ion batteries.
  2. Use a USPS-approved carrier and packaging materials.
  3. Properly package and label the batteries.
  4. Declare the contents of the package accurately.

Remember, it's always better to err on the side of caution when shipping lithium-ion batteries. If you're unsure about the regulations or packaging requirements, it's best to consult with the USPS or a shipping expert.
