6.3 Post Summary Corrections and Reconciliation
Key Takeaways Explain This Topic AI
Post Summary Corrections (PSC) provide an electronic mechanism in ACE to replace unliquidated entry summaries (Types 01, 02, 03) to correct errors prior to liquidation.
Under ACE rules, a PSC must be filed within 300 calendar days from the date of entry OR up to 15 calendar days prior to scheduled liquidation, whichever date occurs first.
PSCs cannot be filed on liquidated entries, informal entries (Type 11), warehouse entries (Type 21), or FTZ entries (Type 06), nor can a PSC change an entry type to or from Type 06.
The Reconciliation Program (19 U.S.C. § 1484(b)) allows importers to enter goods with best available data and flag four specific indeterminable issues: Valuation, Chapter 98 / 9802, Classification, and FTAs.
Reconciliation aggregate entries (Entry Type 09) have bifurcated filing deadlines: strictly 12 months from importation date for USMCA/FTAs (19 U.S.C. § 1520(d)), and 21 months from entry date for Valuation, 9802, and Classification.

6.3 Post Summary Corrections and Reconciliation
Core Regulatory Tenet: Post Summary Corrections (PSC) allow electronic modification of unliquidated entry summaries (ACE) up to 300 days from entry date or 15 days before liquidation (whichever is earlier) | Reconciliation ("Recon" - 19 U.S.C. § 1484(b)) allows flagging of 4 issues: Value, 9802, Classification, and FTAs | Entry Type 09 (Recon entry) deadlines: 21 months for value/9802/class, 12 months for FTAs (19 U.S.C. § 1520(d)) | Recon entries liquidate independently from underlying entries.
The Post-Summary Adjustment Spectrum
In high-volume international trade, commercial realities frequently conflict with the rigid 10-working-day timeframe mandated for filing entry summaries under 19 CFR 142.12. At the time of entry summary filing, complete cost accounting records may be unavailable, year-end transfer prices between related parties may be unsettled, foreign assembly assist values may remain unapportioned, or clerical data entry errors may occur. To manage these adjustments without penalizing compliant trade, customs administration provides two primary pre-liquidation mechanisms:
Post Summary Corrections (PSC): An electronic transaction in ACE enabling filers to voluntarily correct specific data errors on unliquidated entry summaries.
The Reconciliation Program ("Recon"): A formalized statutory framework under Section 484(b) of the Tariff Act of 1930 (19 U.S.C. § 1484(b)) permitting importers to deliberately declare estimated data, "flag" specific indeterminable issues, and true-up liabilities on an aggregate basis months later.
Understanding when to utilize a PSC, when to flag for Reconciliation, and when an administrative protest under 19 U.S.C. § 1514 is required represents one of the most critical analytical competencies tested on the CBLE.
Post Summary Corrections (PSC) in ACE: Operational Architecture
With the full deployment of the Automated Commercial Environment (ACE), CBP eliminated legacy paper Post Entry Amendments (PEAs) for electronic entries. In their place, CBP established the Post Summary Correction (PSC) . Under CBP ACE Entry Summary Instructions and Federal Register notices governing electronic customs procedures:
Full Replacement Mechanism: A PSC is not an amendment or addendum; it is a complete electronic replacement of the entire entry summary record . When a PSC is transmitted, the new submission completely overwrites the prior entry summary data in ACE.
Applicable Entry Types: PSCs may be filed exclusively on Entry Type 01 (consumption free and dutiable), Entry Type 02 (quota/visa consumption), and Entry Type 03 (antidumping/countervailing duty consumption).
Filing Entity: A PSC may be submitted by the original filing customs broker, or by a newly designated customs broker provided that broker holds an active Customs Power of Attorney from the importer of record.
Permissible vs. Prohibited PSC Modifications
Permissible PSC Modifications Prohibited PSC Modifications
Reclassification of merchandise under a different HTSUS subheading. Filing on an entry that has already liquidated on the Bulletin Notice.
Adjusting appraised customs values (transaction value, assists, royalties). Filing on Informal Entries (Entry Type 11) .
Adjusting entered quantities, net weights, or invoice piece counts. Filing on Warehouse Entries (Type 21) or TIB Entries (Type 23) .
Adding or modifying trade remedy liabilities (Section 301, Section 232, AD/CVD). Changing an entry type to or from Foreign Trade Zone (Entry Type 06) .
Correcting Country of Origin or Country of Export declarations. Utilizing PSC to resolve an issue that was flagged for Reconciliation .
Modifying user fees (Merchandise Processing Fee or Harbor Maintenance Fee). Filing after formal notification of a CBP enforcement audit/investigation.
The Strict PSC Time Clock: The "300-Day / 15-Day Rule"
A PSC cannot be filed at just any time during an entry's lifecycle. To prevent interference with automated CBP liquidation cycles, ACE enforces a rigid two-pronged filing window: PSC Filing Deadline = min ( 300 Calendar Days from Date of Entry , 15 Calendar Days Prior to Scheduled Liquidation ) \text{PSC Filing Deadline} = \min \Big( \mathbf{300 \text{ Calendar Days from Date of Entry}}, \; \mathbf{15 \text{ Calendar Days Prior to Scheduled Liquidation}} \Big) PSC Filing Deadline = min ( 300 Calendar Days from Date of Entry , 15 Calendar Days Prior to Scheduled Liquidation )
Operative Constraints of the PSC Window
The 300-Day Ceiling: Under ACE Business Rules, no PSC may be successfully transmitted more than 300 calendar days after the date of entry.
The 15-Day Pre-Liquidation Buffer: Under standard CBP processing, consumption entries are automatically queued in ACE for liquidation on a 314-day cycle from the date of entry. Liquidation batches run on weekly cycles. To prevent filers from transmitting replacement data while CBP's automated accounting routines are calculating final bulletin notices, ACE automatically closes the PSC filing window 15 calendar days prior to the scheduled liquidation date .
Effect of Accelerated or Extended Liquidation: If CBP extends liquidation under 19 CFR 159.12 (e.g., extending the entry to 2 years), the 300-day limit still applies unless CBP administrative guidelines explicitly permit subsequent corrections. If CBP accelerates liquidation (e.g., scheduling liquidation at 180 days), the PSC must be filed at least 15 days before that accelerated date (Day 165).
Duty Payments and Refunds via PSC: If a PSC results in an increase in duties, taxes, or fees, the additional funds must be tendered immediately upon submission. If a PSC results in a duty decrease, CBP does not issue an immediate refund check; instead, the refund is processed upon final liquidation of the entry.
The Customs Reconciliation Program ("Recon" - 19 U.S.C. § 1484(b))
While a PSC is designed to correct discovered mistakes or isolated changes, the Reconciliation Program ("Recon") is an intentional, planned compliance mechanism authorized under 19 U.S.C. § 1484(b) . It recognizes that in modern global supply chains, certain critical data elements are legally indeterminable at the time of entry summary filing.
How Reconciliation Works
Notice of Intent and Flagging: When filing the initial entry summary (e.g., Entry Type 01), the importer "flags" the entry in ACE, signaling to CBP that a specific data element is an estimate and will be reconciled at a future date.
Selective Liquidation: The underlying entry summary liquidates normally as to all unflagged issues (such as standard tariff classification, entered quantities, and user fees). However, liquidation is held open exclusively with respect to the flagged issue.
Aggregate Filing (Entry Type 09): Months later, when final cost accounting or transfer pricing data becomes available, the importer compiles all underlying flagged entries across the reporting period and submits an Entry Type 09 (Reconciliation Entry) .
The Four Authorized Reconciliation Issue Flags
Reconciliation is not a general catch-all for any customs issue. Under CBP Reconciliation guidelines and 19 CFR Parts 142 and 152, Reconciliation is restricted strictly to four authorized issue flags :
Reconciliation Issue Flag Commercial & Legal Application Underlying Regulatory Reference
1. Customs Valuation Used for related-party transfer pricing adjustments under 19 U.S.C. § 1401a, year-end profit adjustments, assists (molds, dies, engineering), royalties, license fees, and retroactive price adjustments. 19 U.S.C. § 1401a; 19 CFR Part 152 Subpart E
2. Chapter 98 / 9802 Assembly & Repairs Used for merchandise assembled abroad with U.S. components under HTSUS 9802.00.80, or foreign repairs/alterations under 9802.00.40/50, where final foreign processing costs and component apportionments require post-importation cost accounting. HTSUS Chapter 98; 19 CFR 10.11–10.24
3. Tariff Classification Permitted ONLY when an importer has a formal pending administrative ruling request with CBP Headquarters (under 19 CFR Part 177) or pending litigation in the Court of International Trade regarding the classification of the imported merchandise. 19 U.S.C. § 1484(b); 19 CFR Part 177
4. Free Trade Agreements (USMCA / FTAs) Used to make post-importation preferential tariff claims under 19 U.S.C. § 1520(d) and USMCA General Note 11, where originating certificates of origin were not in possession at the time of entry summary filing. 19 U.S.C. § 1520(d); HTSUS General Note 11
CRITICAL CBLE DISTINCTION: An importer cannot flag classification under Reconciliation simply because they are unsure of the correct tariff code. Classification flagging is strictly prohibited unless there is an active, formal administrative ruling request pending before CBP or active litigation pending before the CIT.
Entry Type 09 Deadlines: The 21-Month vs. 12-Month Rule
A central focus of the customs broker licensing exam is the bifurcated statutory deadlines governing the submission of the Entry Type 09 Reconciliation Entry : Valuation, 9802, and Classification ⟶ 21 Months from Date of Entry Free Trade Agreements (USMCA / 1520(d)) ⟶ 12 Months from Date of Importation \begin{aligned}
\text{Valuation, 9802, and Classification} &\longrightarrow \mathbf{21 \text{ Months}} \text{ from Date of Entry} \\
\text{Free Trade Agreements (USMCA / 1520(d))} &\longrightarrow \mathbf{12 \text{ Months}} \text{ from Date of Importation}
\end{aligned} Valuation, 9802, and Classification Free Trade Agreements (USMCA / 1520(d)) ⟶ 21 Months from Date of Entry ⟶ 12 Months from Date of Importation
1. The 21-Month Rule (Valuation, 9802, and Classification)
For Reconciliation entries covering Customs Valuation, HTSUS Chapter 98 / 9802 assembly and repair costs, and qualifying pending classification issues, the Entry Type 09 aggregate summary, together with any additional duties, taxes, and interest owed, must be submitted within 21 calendar months from the date of the earliest underlying entry summary included in the reconciliation package.
2. The 12-Month Rule (USMCA and Free Trade Agreements)
For Reconciliation entries covering post-importation Free Trade Agreement claims under Section 520(d) of the Tariff Act (19 U.S.C. § 1520(d)), the deadline is strictly 12 calendar months from the date of importation (not the entry date) of the merchandise. This 12-month limit is enacted by treaty and statute; if an importer misses the 12-month window from the date the cargo arrived in the United States, the preferential duty claim is statutorily forfeited and cannot be extended or cured.
Liquidation of Reconciliation Entries and Protest Rights
The relationship between the liquidation of underlying entries and the liquidation of the Entry Type 09 Reconciliation entry follows strict administrative separation:
Independent Liquidation: The Entry Type 09 Recon entry liquidates independently from the underlying entry summaries. When CBP reviews the aggregate Recon entry, it ascertains the final adjustment. If CBP agrees with the true-up, the Recon entry liquidates "no change" (or processes the aggregate refund or increase).
Challenging Adverse Recon Decisions: If CBP rejects an importer's reconciliation true-up—for example, by disallowing a transfer pricing valuation downward adjustment or rejecting a USMCA origin certification—the importer's sole administrative remedy is to file an Administrative Protest under 19 U.S.C. § 1514 on CBP Form 19 within 180 calendar days from the date of liquidation of the Entry Type 09 Reconciliation entry .
Comprehensive Comparative Matrix: PSC vs. Recon vs. Administrative Protest
Analytical Dimension Post Summary Correction (PSC) Reconciliation Program (Recon Type 09) Administrative Protest (19 CFR Part 174)
Entry Status at Filing Must be Unliquidated (ACE electronic record). Underlying entries unliquidated/flagged for issue. Must be Liquidated (or final adverse decision).
Eligible Issues Any clerical error, classification, value, quantity, or trade remedy. Strictly restricted to 4 flags : Value, 9802, Classification, FTAs. The 7 statutory categories under 19 U.S.C. § 1514(a).
Statutory Filing Window Earliest of: 300 days from entry OR 15 days prior to liquidation . 21 months (Value, 9802, Class) or 12 months from import (FTAs). Strictly 180 calendar days from electronic Bulletin Notice date.
Submission Vehicle Complete electronic replacement summary in ACE. Aggregate Entry Type 09 filed in ACE with true-up data. CBP Form 19 or electronic submission in ACE Protest Module.
Operational Purpose Fixes discovered errors or single-entry revisions. Structural mechanism for delayed, indeterminable cost/origin data. Legal challenge against adverse, final CBP administrative determinations.
Prerequisite Requirement Paid entry summary on Entry Types 01, 02, or 03. Entry summary flagged at filing; participant in Recon. Formal adverse decision or posted bulletin liquidation on CBP.gov.
Interest Treatment Underpayments owe interest from entry summary deposit date. Interest calculated under 19 U.S.C. § 1505 from deposit date to Recon filing. Interest accrues on successful refunds from deposit date to liquidation.
Subsequent Recourse If PSC rejected, entry liquidates; must protest liquidation. Adverse Recon liquidation protested under 19 U.S.C. § 1514 within 180 days. Judicial review in Court of International Trade within 180 days (prepayment req.).
