As anticipated, US Customs has extended by four months the time by which importers must file all electronic entries and entry summaries in ACE. Note, however, that CBP has emphasized that the originally published deadline for the complete cut-over to ACE from ACS is holding fast: “We would like to reiterate that the [extended] transition period does not impact our December 2016 deadline for full implementation of the Single Window via ACE.”
From CSMS #15-000664:
Nov 1, 2015: Beginning of a transition period for electronic entry and entry summary filings in ACE to allow industry and participating government agencies more time to test and provide feedback as they fully transition into the new system. Use of ACE is allowed and encouraged for electronic entry and corresponding entry summary filings for entry types 01, 03, 11, 51, and 52 with or without PGA data.
Feb 28, 2016: At this time, filers will only be permitted to file in ACE, and no longer permitted to file in ACS, all electronic entries and entry summaries. In addition, electronic FDA, NHTSA, and APHIS (Lacey) data must be filed in ACE, and ACS will no longer be available.
July 2016: Upon publication of the Final Rule, ACE must be used for filing AMS, APHIS Core, ATF, CDC, DCMA, DDTC, DEA E&C, EPA, FSIS, FWS*, NMFS and TTB data. Hybrid submissions will no longer be allowed.* This requirement for FWS is contingent on FWS having its regulatory revisions in place by the July 2016 publication of the CBP Final Rule eliminating hybrid filings.
