On September 19, 2016 U.S. Customs and Border Protection (CBP) published a page on the CBP website that details the changes that will be made to transition collections and statement capabilities from the legacy system in ACS to ACE.
According to the CBP page, “While the movement of collections and statement capabilities from ACS to ACE requires fundamental changes in the way collections are processed, there will be little change in the way payments are received from Trade members.”
A provided table lays out a timeline of events in the ACS to ACE statement and collection transition process will take place from October 28 – 31, 2016.
