CBP ACE User Guide on Post Summary Corrections

U.S. Customs and Border Protection has posted a February 2012 user guide on Post Summary Corrections (PSC) of entry summaries in the Automated Commercial Environment (ACE). Importer-authorized ACE entry summary filers can submit a PSC for an existing ACE entry summary type 01 and 03 entry summary, which replaces the existing summary with a new version that will be processed through existing validations, including Census warnings. If a PSC is filed by someone other than the original filer, the original filer will not get a courtesy notice of liquidation via ABI (unless the filing occurs under NILS). Only the original entry filer or most recent PSC filer will be able to view the specific entry summary that was corrected. However, output records are split into "semi-private" (limited information, not the current owner) and "private/owner" information. Note that the filing of PSCs is considered 'customs business.' Post-Summary Corrections User Guide is available here.
