Analyzed Economic Effects
9 provisions identified: 1 benefits, 8 costs, 0 mixed.
Penalties and Suspension for Test Misconduct
PSC test participants may face civil and criminal penalties, administrative sanctions, liquidated damages, and/or suspension from the test for failures such as not following test rules, failing to deposit estimated duties, misuse of the ACE Portal, or unauthorized disclosure. Suspensions may be appealed in writing within 15 calendar days, but in cases of willful misconduct or public health concerns a suspension may be effective immediately.
Full Payment Required Before New PSC
If a PSC increases the amount you owe, you cannot file another PSC until that increase is paid in full and processed by CBP. If only a partial payment is made, the participant will not be able to submit a subsequent PSC.
AD/CVD Increases Must Be Paid Within 3 Days
When a PSC increases antidumping or countervailing duty (AD/CVD) liability, the test participant must submit the additional AD/CVD payment via ACH within three business days of submitting the PSC.
Extended PSC Filing When Liquidation Suspended
For entries where liquidation is suspended beyond 300 days after the date of entry and the entry has an allowable suspension basis (for example: CVD Suspend, ADD Suspend, AD/CVD Suspend, Subject to EAPA, or Subject to Court Injunction), a PSC may be submitted outside the regular 300-day PSC filing window. CBP will post allowable suspension bases on CBP.gov.
Certain Entry Fields Cannot Be Changed
The PSC test prohibits changing certain data elements by PSC, including Importer of Record, date of entry, date of entry summary, bond and surety code, port of entry, and release detail. CBP will reject any PSC that attempts to change these listed elements.
Bond Remains Obligated; New Bond Data Not Accepted
When a PSC is filed, the same bond and surety in effect at entry remain obligated; new bond data cannot be submitted through a PSC. Superseding bonds filed before a PSC remain obligated, and obligations vested before the PSC remain in effect.
Rejected PSCs Must Be Retransmitted Quickly
If CBP rejects a PSC in ACE, the filer may retransmit it within two business days. If no timely retransmission is made, CBP will correct the entry summary and set it for immediate liquidation, which could lead to earlier duty assessment.
ACH Required for PSC Duty Increases
Starting August 5, 2026, importers in the PSC test must pay any increase in estimated duties, taxes, and fees resulting from a post-summary correction (PSC) by electronic Automated Clearinghouse (ACH). Checks and cash will no longer be accepted for those increases, and participants must enroll in either ACH Debit or ACH Credit to make payments.
Interest Not Accepted Before Liquidation
CBP will not accept interest payments on PSC-related increases before liquidation. Any interest owed because of a PSC must be paid after CBP liquidates the entry and issues a bill.
