On August 31, 2016, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) published in the Federal Register a notice [Docket No. ATF 2015R-15] that announces cessation of the pilot program that tested the transfer of data between the Participating Government Agency (PGA) Message Set in the Automated Commercial Environment (ACE) and ATF’s Web-based data analytics system. ACE is the Web-based portal for the collection and use of international trade data maintained by U.S. Customs and Border Protection (CBP). The PGA Message Set is the data related to merchandise regulated by an agency, such as ATF, that CBP will receive electronically from importers for its use as well as for the PGA’s use. The data enables ATF to determine the actual items imported. Although this notice announces the cessation of the pilot program, the mandatory filing date for filing entries in ACE has yet to be determined. Importers should be aware that no changes have been made to the requirement that importers submit their copy of the Form 6A (with Sections I and III completed) to ATF within 15 days of release from CBP custody.
