USPS Shipping Restrictions

If you ship with the United States Postal Service, it’s important to be familiar with U.S. regulations as well as USPS guidelines—especially restricted and prohibited items. Restricted items can be shipped only under certain conditions, while prohibited items can’t be shipped under any circumstances. Additionally, all USPS shipments must follow all local, state, and federal laws to ensure that they meet their final destination.

USPS Domestic Restrictions

Though restricted items have additional requirements to be shipped, some restricted items are commonly shipped. Additional requirements will vary by the type of shipment and it’s up to the sender to fully meet these requirements.

Restricted items include:

USPS International Restrictions

Items shipped internationally must comply with federal laws, USPS standards, and regulations of the country of destination. This means that any item that is prohibited domestically is also prohibited internationally. Each country has its own set of prohibited and restricted items that differs from the U.S. list. It is the responsibility of the sender to familiarize themselves with the destination country’s policies before sending a shipment.
