Post-summary correction
Also called: PSC
An electronic correction to a US entry summary filed by the importer or broker after the entry summary has been accepted but before liquidation, within the time window set by CBP. It can change classification, value, origin or other data and adjusts the duty deposit.
In practice
A PSC is the simplest way to fix errors before liquidation, but it is not a substitute for a prior disclosure when the error suggests a violation.
