On August 14, 2019, U.S. Customs and Border Protection (CBP) announced in a Federal Register Notice (FRN), a modification to the National Customs Automation Program test expanding the time-period for processing post-summary corrections (PSCs).
The modification extends the deadline for filing a PSC when an importer requests, and is granted, an extension of liquidation by allowing a PSC to be transmitted up to 15 days prior to the extended liquidation date.
Per the FRN, comments and additional inquiries should be sent to the OTENTRYSUMMARY@cbp.dhs.gov email box.
