Although staff at the USPS New York ISC works closely with the United States Customs and Border Protection (CBP), (they are in the same building after all), the two organizations have very distinct roles in the processing of incoming and outgoing shipments.

The CBP’s sole responsibility is to inspect all international packages entering or leaving the USA. They will check the contents of shipments to ensure no prohibited items, (foods, animals, drugs, and counterfeit goods for example) are contained within.

USPS on the other hand is responsible for the sorting and delivery of items entering the USA, (and the successful dispatch of items leaving the USA).

So although it is true to say that a package goes through the customs process at ISC New York NY USPS, the item is actually with the CBP as this happens.

Here’s a summary of what happens when the CBP checks a package within the ISC New York facility:

  • A general check will involve non-intrusive inspection techniques, (i.e checks without opening the package).
  • A suspicious package will be taken to an inspection area, where it will be examined by sniffer dogs and/or subjected to x-rays
  • Finally, if suspicions continue the package will be opened for a physical inspection.

However, the majority of shipments are clear customs with no issues and are handed back to USPS from the CBP for delivery to the destination address.

How Long will my Package be at the ISC New York?

Although the customs clearance process is standard procedure, the length of time you can expect to wait until your package leaves the ISC processing facility in New York City varies widely.

A small package that is part of a single consignment, (i.e not a bulk shipment) may take a matter of hours to be processed through the ISC once the CBP has it in its possession.

Conversely, if your item is part of a bulk import (along with many other consignments) it could take the CBP several days to inspect the shipment.

And remember, this duration doesn’t take into account unloading, sorting, and dispatch times.

Issues that impact processing times at the ISC New York:

  • Declaration of the package contents
  • Correct and fully filled in documentation
  • Where the package has come from (i.e which country)
  • The size and weight of the package
  • Whether tax or duties are owed
  • Staffing levels (Covid staff reductions had massive impacts)
  • The volume of packages arriving (seasonal variations)

If your package tracking status remains stuck within the ISC New York facility for more than 5 business days you will have grounds to contact USPS to see what the delay is.

However, without further updates, it is difficult to determine whether the hold-up is due to general delays in the facility or if a problem has occurred during customs clearance.

The latter will generally trigger an alert advising the shipper or recipient on what issues have taken place with the CBP.

All that being said, if the tracking status does not update and your package seems stuck in the ISC, you should contact USPS Customer Service to find out more.
