International Mail Rules and Regulations

When sending international mail, it is important to know the rules and regulations regarding its inbound, outbound, and examination by Customs and Border Protection (CBP). Before submitting your shipments, be sure to read the following guidelines:

Rules and regulations for inbound international mail

The United States Postal Service offers a variety of services for inbound international mail. These services are in accordance with the rules and regulations set by the Universal Postal Union (UPU). The services include verification of receipt and processing through a secure mail system, and signatures upon delivery. The originating postal operator compensates the delivering postal operator for the services provided. However, the Postal Service is not authorized to charge a premium for inbound international mail.

Inbound international mail falls into two main categories: letter class and package post. Letter class mail includes letters, packages, post cards, and aerogrammes that are mailed at letter rate. Packages and aerogrammes that are mailed at letter rate will be subject to Customs examination. Generally, the rules and regulations governing international mail are the same as those governing domestic mail. If you’re sending a package overseas, you must comply with the rules and regulations for inbound international mail.

Forms required for shipments

If you’re shipping goods to a foreign country, you’ll need to fill out several forms. These documents are commonly known as “Material Safety Data Sheets” (MSDS) and provide information about hazardous materials. Unlike USPS mail, however, international mail shipments must follow international rules and regulations. These regulations often include additional forms, such as customs declarations and manifests, which may have a commercial value.

Historically, the international mail process is still mostly paper-based. Information from the sender is provided to the FPO, which in turn provides the information to the USPS and CBP. In recent years, the international mail system has embraced the use of electronic data to expedite customs clearance and identify high-risk items. But now, CBP is moving toward requiring that mail shipments use AED (Automated Electronic Data).


The USPS provides several options for shipping mail internationally. Different options have different prices and are geared towards different purposes.
