The United States Postal Service (USPS) has specific guidelines and restrictions for mailing liquids, including liquids in containers, liquids in packages, and liquids in envelopes. Here are some general guidelines:

Liquids in Containers:

• USPS allows mailing liquids in containers, such as perfume, cologne, shampoo, and lotion, as long as they are properly packaged and meet the following conditions:
  • The container is securely sealed and leak-proof.
  • The liquid is not flammable or hazardous.
  • The package is properly labeled and marked with the correct postage.
• However, some liquids, such as aerosols, are prohibited from being mailed.

  • The liquid is not flammable or hazardous.
  • The package is properly labeled and marked with the correct postage.
• However, some liquids, such as hazardous materials, are prohibited from being mailed.

Liquids in Envelopes:

• USPS does not allow mailing liquids in envelopes, except for very small amounts of liquid, such as a few drops of perfume or a small amount of ink.
• If you need to mail a liquid in an envelope, you must use a special envelope designed for mailing liquids, such as a "liquid mailer" or a "leak-proof envelope."

Additional Requirements:

• All packages containing liquids must be properly packaged to prevent leakage or damage during transit.

  • Hazardous materials, such as chemicals, pesticides, or radioactive materials.
  • Liquids that are considered "dangerous goods" by the International Air Transport Association (IATA).
