Can i mail co2 cartridges

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. Prohibited: CO2 cartridges are prohibited from being shipped by air, including by Priority Mail Express, Priority Mail, and First-Class Mail.
  2. Restricted: CO2 cartridges can be shipped by ground, but only through the USPS's Parcel Post service, and only if they are properly packaged and labeled as hazardous materials.
  3. Packaging requirements: CO2 cartridges must be packaged in a sturdy box with adequate cushioning to prevent damage during transit. The box must also be marked with the words "Hazardous Materials" and "CO2 Cartridges" in large letters.
  4. Labeling requirements: The outside of the package must be labeled with the following information:
    • "Hazardous Materials"
    • "CO2 Cartridges"
    • "Non-flammable Gas"
    • "UN 1942"
    • "Class 2.2"
  5. Quantity limits: There are limits on the quantity of CO2 cartridges that can be shipped by mail. For example, the USPS prohibits shipping more than 12 CO2 cartridges in a single package.
  6. Special permits: If you plan to ship large quantities of CO2 cartridges or if you have specific requirements for shipping these items, you may need to obtain a special permit from the USPS or PHMSA.

It's important to note that these regulations may vary depending on the specific type of CO2 cartridge, its size, and its intended use. If you're unsure about the regulations or need more information, I recommend contacting the USPS or PHMSA directly.

In summary, while it is possible to mail CO2 cartridges, there are specific regulations and restrictions that must be followed to ensure safe and compliant shipping.
