This document announces that U.S. Customs and Border Protection (CBP) plans to conduct a National Customs Automation Program (NCAP) test relating to truck shipments of commercial goods that transit from a point of origination in Canada through the United States to a point of destination in Canada. Under the NCAP test, CBP will use a new filing code to identify shipments as being part of the In-Transit Manifest Pilot Program in CBP’s Automated Commercial Environmental (ACE) Truck Manifest System. Test participants will submit electronically an in-transit manifest with a relaxed validation for the value data element and they will not have to provide the Harmonized Tariff Schedule (HTS) number. This notice provides a description of the NCAP test and specifies the duration and locations of the test. It also invites public comment on any aspect of the test.
