On October 3, 2016, U.S. Customs and Border Protection (CBP) published in the Federal Register a notice delaying the effective date of ACE becoming the sole CBP-authorized electronic data interchange (EDI) system for processing electronic drawback, duty deferral entries and entry summary filings. On August 30, 2016, CBP published a notice in the Federal Register announcing October 1, 2016 as the effective date. This notice announces that the effective date for the transition to ACE as the sole CBP-authorized EDI system for electronic drawback and duty deferral entry and entry summary filings is delayed until further notice.

CBP will publish a subsequent notice announcing the effective date when ACE will be the sole CBP-authorized EDI system for processing electronic drawback and duty deferral entry and entry summary filings, and ACS will no longer be a CBP-authorized EDI system for purposes of processing these filings
