Effective July 29, 2019, members of the Trade community will be required to report all in-bond exports, arrivals and diversions electronically through the Automated Commercial Environment (ACE).  Air shipments will continue to be exempt from these requirements and trade members can still request manual posting by Customs and Border Protection (CBP) for these shipments.   CBP will no longer accept paper copies of the CBPF 7512 to perform arrival and export functionality.   An ACE edit will issue a rejection if these actions are not performed.   At this time, no date is set for implementation of the provision requiring the 6-digit Harmonized Tariff Schedule number requirement for Immediate Transportation movements.  The Automated In-Bond Processing Business Process Document is the official publication which provides both CBP and the trade community with guidance, requirements and responsibilities when processing in-bond cargo. 

In-Bond Arrival
When your bonded shipment first entered the US and was allowed to proceed, this began the In-Bond movement. The bond was opened.  A bond is being opened when the shipment is cleared to proceed in bond at the Port of Entry. Once your bonded shipment has arrived at its final In-Bond destination in the US, you will need to report its arrival to CBP within 48 hours to close out or "cancel" the bond.

U.S. In-Bond Destination
The inland CBP port that the goods will be moving in bond to. This can't be the same as your port of arrival, it must be the "far side" U.S. destination of the bond.

Export of In-Bond
​For in-bond shipments of type "Transportation and Exportation" you may also need to report the export in the same way. First you'll need to make sure that the bond is already in arrived status, and of course you need to be sure that the export has already physically taken place.
