Per CSMS #16-000144, US Customs has posted Draft Version 2.0 of the ACE Cargo Release Business Process Document.
One of the many benefits of the migration to ACE is that CBP has created process documents to assist the trade in understanding the processes to be used in ACE. Specifically, there is now a process document for both Cargo Release and Entry (Entry Summary.) Previously, the trade had to rely on the CATAIR for tips on when and how to send an ABI transmission to CBP. These business process documents are a valuable tool and clearly explain when it is appropriate to send a certain type of transmission from another (e.g. Cargo Release ‘Update’ versus ‘Replace’).
