Liquidation in ACE

Last Updated | February 8, 2018

On February 24, 2018, U.S. Customs and Border Protection will deploy Liquidation capabilities in ACE at which time liquidations will no longer be filed/processed in the Automated Commercial System (ACS) and must be done via ACE. Please note: posting of paper C16 notices at local ports was discontinued in January 2017 and replaced online with the Official Notice of Extension, Suspension and Liquidation. Details are outlined below.

Deployment Support Call:

CBP’s Trade Transformation Office (TTO) will host a daily support call from February 26, 2018 to March 2, 2018 between 2:00 PM ET and 3:00 PM ET to answer questions related to the February 24th deployment.

  • Line 1: (877)-336-1828 / PC: 6124214

The following are the high-level changes for processing liquidations in ACE beginning January 2018:

New Weekly Processing: Liquidations will no longer occur on a two-week cycle. Liquidations will process weekly, with entry summaries liquidating every Friday. Once an entry summary is liquidated, ACE will automatically populate a liquidation date equal to the next immediate Friday. Liquidations processed before 11:59:59 PM Wednesday ET will post Friday of the same week; liquidations occurring after this timeframe will post the following Friday.

Temporary Importations Under Bond (TIB) Extensions: TIB Extensions requested by Trade will automatically be accepted in ACE, but CBP will have the ability to deny an extension as necessary. TIBs may only be extended for up to three years.

Deem Liquidations: For entry summaries that are deem liquidated, they will display on the electronic bulletin as “deem liquidated” for the basis of liquidation.

ACE Reports

ACE Reports will support liquidation data in ACE effective March 17, 2018. This will include pre-defined reports along with the ability to query for data down to a case number. Full details are available by way of the ACE Reports Information Notice.

Effective January 14, 2017

Electronic Bulletin, No More Paper Postings: CBP no longer prints C16 notices for posting to the liquidation bulletin. This process was replaced with an entirely electronic process available on www.cbp.gov.  The electronic Official Notice of Extension, Suspension and Liquidation provides public notice.  An ACE account is not required to access this information. Liquidations are posted 365 days a year, including holidays. Trade members are able to search the electronic bulletin by filer or date the event occurred.

Postings are kept online for 15 months to allow time to search for a liquidation. After 15 months, a request will need to be made to CBP to view a past liquidation. Please note, for entry summaries with liquidation dates in the future, the liquidation reports will no longer display as "liquidated" and will instead display "pending" as the liquidation status.

Extensions and Suspensions:  CBP no longer prints notifications of extension and suspension. The Official Notice of Extension, Suspension and Liquidation serves as the official notice for extensions and suspensions. Sureties and filers still receive extension and suspension courtesy notices, which are sent via ABI. Those filing in paper will not receive a courtesy notice, as courtesy notices are only available to those filing electronically. If necessary, a liquidation may be extended up to three years.
