Can i send lithium batteries in first class mail

According to the United States Postal Service (USPS), lithium batteries are considered hazardous materials and are subject to specific regulations when shipping by mail.

In general, lithium batteries are not allowed in First Class Mail, and you should not attempt to send them through this service. Here's why:

  1. Hazardous Materials Regulations (HMR): Lithium batteries are classified as hazardous materials under the HMR, which requires special handling and packaging to ensure safe transportation.
  2. USPS Prohibitions: The USPS prohibits the mailing of lithium batteries in First Class Mail, as well as in Priority Mail and Priority Mail Express, unless they are properly packaged and declared as hazardous materials.
  3. Packaging Requirements: To ship lithium batteries by mail, you must use a special package that meets the USPS's packaging requirements, which include:
    • A sturdy outer packaging that can withstand normal handling and transportation.
    • A protective inner packaging that prevents the batteries from coming into contact with each other or with other items in the package.
    • A warning label indicating that the package contains hazardous materials.
  4. Declaration Requirements: You must also declare the lithium batteries as hazardous materials on the shipping label and provide additional information, such as the type and quantity of batteries, and the precautions to be taken in handling and storing them.

If you need to ship lithium batteries, you should use a shipping service that is specifically designed for hazardous materials, such as UPS or FedEx. These carriers have their own regulations and procedures for shipping lithium batteries, and they will provide you with the necessary packaging and documentation.

Remember, it's always better to err on the side of caution when shipping hazardous materials. If you're unsure about the regulations or procedures for shipping lithium batteries, it's best to consult with the USPS or a shipping carrier directly.
