For warehouses operating in the US and receiving air cargo transferred to their facility on an airwaybill need to receive electronically from CBP electronic notification of the release of the cargo.  In cases where there is a hold on the cargo or an inspection is required by CBP, the FSN message will indicate to the warehouse to hold the cargo and segregate it waiting for the inspection to take place by CBP.

Participation by a warehouse in the Freight Status Notification System is under a larger CBP program known as Air AMS (Automated Manifest System) or ACE Air eManifest.

A warehouse is identified by CBP under a Facilities Information and Resources Management System (FIRMS) code.  Warehouses can include the following:

  • CFS (Container Freight Station) or
  • ECCF (Express Consignment Carrier Facility).

Some of the differences between a CFS or ECCF when it comes to customs clearance of shipments by CBP include the following;

MPF (Merchandise Processing Fee Charged by CBP?NoYes
CBP Staff on Weekend?NoYes
Time for CBP to Inspect Shipments with FSN Hold Message?1-5 days24 hours
Total Clearance Time1-5 days24 hours
