Self-Filing a Post Summary Correction (U.S. Only)
A Post Summary Correction (PSC) is an amendment to an Entry Summary (excluding informal entry, type 11 or 12) prior to liquidation; yet after US Customs and Border Protection’s (CBP) acceptance of that Entry Summary, payment has been processed, and the entry is scheduled for liquidation.
A PSC can be filed up until the 300th day (11:59 PM Eastern time) after the entry date or up to midnight Eastern time on the 15th day prior to the scheduled liquidation date, whichever is earlier. Since CBP views a PSC as a full replacement of the Entry Summary data currently on file, the PSC will be accepted as the most up-to-date data available. However, it is important to remember that once CBP reviews the PSC, CBP may change the associated collection information to reflect any resulting monetary changes.
Most Entry Summary data elements can be updated using a PSC. However, elements affecting admissibility are not allowed to be changed in a PSC.
Just like with conventional summary filings, there are many edits and validations on the CBP side and several types of rejections can be encountered with a PSC filing. If the data is not accepted by ACE, then the Entry Summary data on file in ACE will remain unchanged.
There is no limit to the number of PSC filings ACE will accept for an Entry Summary. However, the filer must provide reasons for the data change on each PSC. It is also important to remember that once a PSC has been accepted by CBP, the filer can no longer submit conventional filings to CBP for that entry.
The option to self-file a Post Summary Correction (PSC) in the Entry Verification solution provides you the ability to push data to the ONESOURCE Automated Broker Interface (ABI) module to validate the entry and allow filing directly from ONESOURCE to US Customs and Border Protection (CBP).
Self-filing a Post Summary Correction within ONESOURCE allows you to:
- Leverage the ONESOURCE ABI module to complete the required entry validations necessary for PSC filing
- Transmit PSC data directly from ONESOURCE to CBP
- Maintain a history of all corrections made to an entry within ONESOURCE Entry Verification
- View replies from CBP for a PSC that has been filed through ONESOURCE
When the self-filing capability is enabled within Entry Verification, the
Declaration Correction
screen will show an additional Validations
column on the All Entries
tab. 
When an entry’s status changes to the configured
Requires Correction
status, the system will run the entry data against the preconfigured ABI validations. The validations being run are checking for entry completeness per CBP requirements should a PSC need to be filed.Any system configured for validations (even if it has not been configured to self-file PSCs), will run validations so that data may be provided in the report to third parties for subsequent filing.
ABI Validations
To review the data points that have been flagged by the validations, choose an entry from the grid and click its corresponding
ABI Validations
link. 
Clicking
ABI Validations
will open a pop-up containing the entry’s validation errors:

Edit
. Add any additional changes that were not captured on the Declaration Correction
screen. 
After making additional changes, click
Validate
at the top of the screen to re-run validations. This will redirect the user to the “Validation Summary” tab so any outstanding validations can be reviewed. After all errors are corrected, the
Validation Summary
tab will be blank and the Entry Status will update to VALIDATED
.
Once the entry is in
VALIDATED
status, the Finalize
button will turn blue and allow the user to finalize the entry. Once clicked, the Entry Status will change to FINALIZING
. No changes can be made to the entry while it is in a FINALIZING
status. 
After the process is complete, the Entry Status will change to
FINALIZED
. Once the entry has finalized, a message will appear at the top of the screen: “Entry has been finalized”.After the entry has been finalized, review the
Header Post Summary
and/or Line Post Summary
tabs. On these tabs, the system will automatically calculate the PSC Reason Codes based on the changes made to the entry.In the event a code is incorrect or missing, these codes can be manually updated without having to Revalidate or Refinalize. Refinalizing will remove any changes made to the Reason Codes.
Changes to header information on the entry will trigger the
Header Post Summary
tab to be visible on the entry. The
Explanation
text box is used for providing details on why a change was made to the entry. The Reason Code
box is used for choosing the CBP Reason Code that best explains why the entry is being re-filed with a Post-Summary Correction.
