Can you mail liquid through the post office

In general, the United States Postal Service (USPS) has specific guidelines and restrictions for mailing liquids, gels, and aerosols. Here's what you need to know:

General Guidelines:

  1. Liquid, Gel, or Aerosol Content: The USPS prohibits mailing liquids, gels, and aerosols in envelopes or packages that are not specifically designed to contain them.
  2. Packaging Requirements: If you need to mail a liquid, gel, or aerosol, you must use a leak-proof, tamper-evident container that is specifically designed for shipping hazardous materials.
  3. Labeling Requirements: You must clearly label the outside of the package with the words "LIQUID," "GEL," or "AEROSOL" and indicate the contents.

Specific Restrictions:

  1. Perfumes, Cosmetics, and Toiletries: These items are generally allowed in small quantities (less than 3.4 ounces or 100 milliliters) in a clear, quart-sized zip-top bag and placed in a checked bag or package.
  2. Medications: Prescription medications in their original packaging are usually allowed, but it's best to check with the USPS and your healthcare provider for specific guidance.
  3. Food and Beverages: Liquids, gels, and aerosols related to food and beverages are generally allowed, but you should check with the USPS and the recipient's local postal regulations.

Prohibited Items:

  1. Hazardous Materials: The USPS prohibits mailing hazardous materials, such as flammable liquids, corrosive substances, and toxic materials.
  2. Perishable Items: The USPS does not accept perishable items, such as food, drinks, or biological samples, that require refrigeration or special handling.

Conclusion:

In summary, while the USPS does allow mailing liquids, gels, and aerosols under specific conditions, it's essential to follow the guidelines and restrictions outlined above to ensure safe and compliant shipping. If you're unsure about a particular item, it's always best to check with the USPS or consult their website for more information.
