On January 17, 2017, U.S. Customs and Border Protection (CBP) published in the Federal Register a notice announcing that the effective date for the modifications to the National Customs Automation Program (NCAP) tests regarding Reconciliation, Post-Summary Corrections (PSC), and Periodic Monthly Statements (PMS) is delayed until further notice. On December 12, 2016, CBP published a notice in the Federal Register announcing modifications to the National Customs Automation Program (NCAP) test regarding reconciliation, and the transition of the test from the Automated Commercial System (ACS) to the Automated Commercial Environment (ACE). The modifications made by this notice were to be effective on January 14, 2017. On December 12, 2016, CBP published in the Federal Register a document announcing CBP’s plans to modify and clarify the NCAP test regarding PSC claims to entry summaries that are filed in the Automated Commercial Environment (ACE), as well as the PMS test. The notice liberalized and eliminated some requirements needed for the filing of PSCs; however, it also placed burdens on the importer in the form of a restriction and a prohibition. Subsequently, CBP published a notice in the Federal Register on January 9, 2017 (see below), to remove the restriction imposed on all PSC filings to make payments within three business days of submitting the PSC, with the exception of entry type 03 filings, and to remove the prohibition of filing additional PSCs until additional duties, fees and taxes and PMS tests were to have been effective January 14, 2017. This notice announces that the effective date for the modifications to these NCAP tests has been delayed until further notice.
