Duty Deferral in ACE

Last Updated | July 27, 2017

On September 16, 2017 U.S. Customs and Border Protection will deploy Duty Deferral capabilities in ACE at which time Duty Deferral entries will no longer be filed/processed in ACS and must be done via ACE.

The current Deployment G Release schedule is as follows:

  • ACE Deployment G, Release 2 (September 16, 2017) – Non-ABI Entry Summary/Lineless (for CBP only), Duty Deferral, e214, and Manufacturer ID Creation
  • ACE Deployment G, Release 3 (December 16, 2017) – Statements
  • ACE Deployment G, Release 4 (February 24, 2018) – Reconciliation, ACE Core Drawback and TFTEA Drawback, Liquidation and Automated Surety Interface (ASI)

This phased approach ensures that the ACE core post release capabilities continue to interface seamlessly with collections in the legacy system.

Please be aware that the content below in this information notice is under revision and will be updated with additional information as it becomes available.
