Duty Deferral

On September 16, 2017, CBP 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. Data will be migrated from ACS to ACE, so even if the Duty Deferral process began in ACS, Duty Deferral information submitted on/or after September 16 must be filed in ACE. Trade users will not need to re-enter Duty Deferral information in ACE that was transmitted to ACS.

The majority of Duty Deferral processing will remain the same in ACE as it has been in ACS.

What will change with Duty Deferral in ACE?

There are only minor changes to Duty Deferral processing in ACE.

Importer Security Filing (ISF)

Beginning September 16, 2017, trade filers will begin submitting Automated Broker Interface (ABI) ISF transactions in ACE, at which time no further ISF submissions will be done in ACS. Filers should ensure their software is up to date and able to transmit to CBP. The ACE Portal will remain available for ISF submissions from small volume filers (less than 12 a year), and for ocean manifest filers through existing manifest technical standards.

There are minor software coding changes required for ISF ABI transmissions, and vendors or self-filers should be aware of the revised transmissions standards. The following Customs and Trade Automated Interface Requirements (CATAIR) chapters may be referenced:

• ACE ABI Batch and Block Control
• Importer Security Filing
• Importer Security Filing: Status Notification

Updates to this notice will be made prior to the deployment with information on a cutover timeline for the migration of data and submissions to ACE.
