In a Federal Register Notice published November 1, 2017, U.S. Customs and Border Protection (CBP) announced changes to filing a Post Summary Correction (PSC).
Among the changes, CBP has extended the timeframe for filing a PSC to be, “within 300 days of the date of entry or 15 days prior to the scheduled liquidation date, whichever date is earlier.” PSCs were to be filed within 270 days from entry, and not within 20 days from the scheduled liquidation date.
Additionally, CBP has clarified that PSCs may be filed on TIB entries with some restrictions. A PSC for a TIB may be filed only to correct data elements that do not change a TIB entry to another entry type or change another entry type to a TIB entry.
