United States Postal Service (USPS) is the largest shipping service provider in the U.S. that also deals with international shipping of products.

Receiving a package from another country entails a lengthy series of steps. Hence, USPS tries to keep you informed of every progress your consignment has made with the help of a tracking system and mobile notifications.

So when you see the “Inbound Out of Customs” delivery status while tracking your international parcel, it means that your package has cleared the Customs checks, entered the U.S., and been allowed for final delivery.

After clearance, the Customs officers will hand over your package to the USPS handler, and you can expect to receive it within the next few days.


USPS provides the facility of sending and receiving mail from more than 180 countries worldwide, and on average, they process eight million international parcels daily.

Let’s discuss the processes involved in receiving a USPS parcel from abroad in the United States, why Customs stops your package, and how Customs work.

1. Parcel Reaching U.S. Customs Facility

Usps Form

Whenever you purchase something from an international online store or someone sends a parcel from overseas, your package will first go to U.S. Customs and Border Protection (CBP) for inspection before entering the U.S. and getting to the USPS facility.


USPS cannot directly collect parcels at the airport; they have to wait for Customs officials to inspect the packages for any illegal items. They will transfer the parcels to USPS handlers if nothing violates U.S. laws and regulations.

Why Do Customs Stops and Check Your Parcel?

The answer to this question is pretty simple; Customs may inspect your USPS parcel for several reasons, including:

  • To verify the contents of the package and ensure that they comply with current import laws and regulations.
  • If applicable, collect duties and taxes on the items in the parcels.

How Do Customs Work?

Customs officials pick up the parcels directly from the port and take them to any of the five primary International Service Centers (ISCs) in the United States to ensure the packages contain nothing illegal.

The Customs authorities use advanced technology, including X-rays, scanners, and chemical analysis, to screen parcels for security threats and prohibited items.


According to a report, more than 650 million packages are received by U.S. Customs each year.

2. Parcel Inbounding Out of U.S. Customs

Delivery To Usps

Once cleared by Customs, your package is forwarded to USPS handlers, who transport it to the USPS international facility.

At this stage, the delivery status of your package changes to “Inbound Out of Customs,” which means that it is allowed to enter the U.S., and USPS is now responsible for delivering them to you.


During the inspection, a USPS official should be at the ISC who prepares the documentation for getting custody of parcels from Customs.

3. Parcel Reaching USPS Regional Facility
