Can co2 cartridges be mailed

In the United States, the mailing of CO2 cartridges is regulated by the United States Postal Service (USPS) and the Pipeline and Hazardous Materials Safety Administration (PHMSA).

According to the USPS, CO2 cartridges are considered hazardous materials and are subject to specific regulations and restrictions when shipped by mail. Here are some general guidelines:

  1. Hazardous Materials Declaration: CO2 cartridges must be declared as hazardous materials on the shipping label and in the shipping documentation.
  2. Proper Packaging: CO2 cartridges must be properly packaged to prevent leakage or damage during transit. This includes using leak-proof containers, padding, and securing the cartridges to prevent movement.
  3. Limited Quantity: CO2 cartridges can only be shipped in limited quantities, typically up to 1 pound (0.45 kg) per package.
  4. Special Handling: CO2 cartridges require special handling and may require additional fees for shipping.
  5. Prohibited in Certain Mail Classes: CO2 cartridges are prohibited in certain mail classes, such as Priority Mail Express and First-Class Mail International.

PHMSA also regulates the transportation of CO2 cartridges by air, land, and sea. According to PHMSA, CO2 cartridges are classified as a hazardous material and must be shipped in accordance with the Hazardous Materials Regulations (HMR).

In summary, while CO2 cartridges can be mailed, they must be properly packaged, declared as hazardous materials, and shipped in accordance with USPS and PHMSA regulations. It's recommended to check with your local post office or a shipping carrier for specific guidance on shipping CO2 cartridges.
