Nonmailable Items: What You Can't Send Through the Mail

Nonmailable refers to items that cannot be sent through the mail or postal service due to their content, size, weight, or other reasons. These items are typically prohibited or restricted by the United States Postal Service (USPS) or other mail services.

Some examples of nonmailable items include:

1. Hazardous materials: Items that are flammable, corrosive, or toxic, such as chemicals, batteries, and paint, cannot be sent through the mail.
2. Weapons: Firearms, ammunition, and other weapons are prohibited from being sent through the mail.
3. Dangerous goods: Items that are considered dangerous, such as lithium batteries, explosives, and radioactive materials, cannot be sent through the mail.
4. Large or heavy items: Items that are too large or heavy to be safely transported through the mail, such as furniture or appliances, may be nonmailable.
5. Perishable items: Items that are perishable, such as food or flowers, may not be able to be sent through the mail due to the risk of spoilage or contamination.
6. Cash and other valuable items: Senders are generally prohibited from sending cash or other valuable items through the mail, as these items can be easily lost or stolen.
7. Illegal items: Items that are illegal, such as drugs or counterfeit goods, cannot be sent through the mail.

It's important to check with the USPS or other mail services before sending any item through the mail to ensure that it is not nonmailable and to determine any special requirements or restrictions that may apply.
