In ACE eManifest there is currently no functionality to declare a Carnet Shipment. As such, highway carriers can simply leave the Carnet Shipment off when preparing their manifest and have the driver verbally declare the shipment and present the Carnet document to the officer. If there are no other shipments on the truck, it is recommended that the carrier still prepare an empty truck manifest so that prior notice requirements are still met.
The "Admission Temporaire - Temporary Admission" (ATA Carnet) is an international customs document that allows for the temporary, duty-free importation of merchandise, replacing the typical customs documents required for entry. The carnet serves as a guarantee against duties that may be owed if the merchandise is not re-exported.
A carnet is valid for one year, and within that period, you can make unlimited trips. It can also be used to move goods within the U.S., as outlined in the regulations under 19 C.F.R. Part 114.
Local associations issue carnets to residents. In the U.S., the U.S. Council for International Business, located at 1212 Avenue of the Americas, New York, NY, is the designated issuing and guaranteeing organization for CBP. A fee is charged for this service.
