ACE Entry Summary Reports: What Every Importer Should Pull

Key Points

• ACE entry summary reports give importers line-level visibility into every entry filed under their Importer of Record number, including HTS classifications, duty programs, and amounts paid.
• Monthly reconciliation of ACE data against broker invoices is the fastest way to catch misclassifications, missing Chapter 99 overlay codes, and unpaid Section 301 or Section 232 duties before CBP does.
• Common discrepancy patterns include wrong country of origin, omitted special program indicators (such as FTA claims), and duplicate or split entry lines that distort duty totals.
• Importers have access to ACE report data through the ACE Secure Data Portal; access requires a portal account and appropriate role permissions set up with CBP.
• Errors discovered through self-review can often be corrected by prior disclosure or protest before they become formal penalty actions.

ACE entry summary reports are downloadable records pulled from U.S. Customs and Border Protection's Automated Commercial Environment that show every entry summary filed under your Importer of Record number, with line-level detail on classifications, declared values, duty rates, and special program claims. Reviewing these reports monthly lets you verify that your broker's filings match your purchase orders and commercial invoices, and catch errors while correction is still straightforward. The links throughout this article go to the primary documents: CBP's ACE portal guidance, the Harmonized Tariff Schedule, and relevant statutes and regulations. Read the source.

What ACE entry summary reports are and how to access them

The Automated Commercial Environment is CBP's primary trade-processing platform. Every entry summary (CBP Form 7501) that your broker files on your behalf is stored in ACE and associated with your Importer of Record number. ACE gives you the ability to query that data through the ACE Secure Data Portal, which is the web interface CBP provides to trade account holders.

Getting portal access

To pull your own data, you need an ACE portal account with the "Importer" trade account type. Your company's Account Owner sets up user roles; common roles include Trade Account Owner, Proxy Trade Account Owner, and Report User. CBP's ACE portal overview page explains the account hierarchy and how to request access. Once your account is active, the Reports tab gives you access to pre-built and ad hoc queries against your entry data.

Report formats

ACE generates reports in standard formats you can open in spreadsheet software. The most useful for compliance review are entry-level and entry-line-level exports, which you can filter by date range, port of entry, HTS chapter, or country of origin. Pull at minimum a rolling 12-month export so you can spot trends, not just one-off errors.

What the reports show: entries, lines, duties, and programs

Each row in a line-level ACE report corresponds to one tariff line on one entry summary. The fields most relevant to compliance review are described below.

Entry-level fields

• Entry number and entry type. The seven-character entry number ties back to the physical CBP Form 7501. Entry type codes identify the import category, such as consumption entries or informal entries.
• Entry date and liquidation date. Liquidation is CBP's final assessment of duties. Most entries liquidate by operation of law within one year of entry; the liquidation date is your clock for filing a protest if you disagree with the assessed duties.
• Port of entry. Useful for spotting whether certain ports show higher error rates, which can signal a broker team or process issue at a specific location.

Line-level fields

• HTS number. The 10-digit classification code determines the base duty rate. Verify it against the Harmonized Tariff Schedule of the United States for each product you import.
• Country of origin. Origin drives eligibility for free trade agreement (FTA) rates, and it determines which Section 301 list, if any, applies. A wrong origin code is one of the most consequential single-field errors in a filing.
• Entered value. This is the declared customs value on which ad valorem duties are calculated. Compare it against your commercial invoice; discrepancies may signal first-sale or assists issues that need separate analysis.
• Duty rate and duty amount. The report shows both the claimed rate and the calculated duty. Cross-check the rate against the HTS for the entry date, not the current date, because rates change.
• Special program indicator (SPI). SPIs are single-letter codes that identify preferential duty treatment, such as FTA claims. A missing SPI on an FTA-eligible shipment means you overpaid duties; a fabricated SPI means you underpaid and may owe back duties with interest.
• Chapter 99 overlay codes. When additional duties apply under Section 301 or Section 232 trade actions, brokers must list both the base HTS chapter classification and the applicable Chapter 99 HTS provision. ACE line data shows both codes, so you can confirm the overlay was correctly applied or, if your product has an exclusion, that the exclusion code was used. For background on how Chapter 99 codes work alongside base classifications, see our guide on HTS Chapter 99 explained.

Why monthly reconciliation matters

Most importers review broker invoices when they arrive, but invoice review alone does not confirm what CBP actually received. A broker can invoice you for a correct duty amount while filing an entry with a different classification or value. ACE data is what CBP acts on, not your invoice.

The liquidation window

Once an entry liquidates, your options narrow significantly. You have 180 days from the date of liquidation to file a protest under 19 U.S.C. 1514 if you believe CBP assessed duties incorrectly. Miss that window and your administrative remedy is generally gone. Monthly ACE review keeps you inside the correction window for most entries, because you will catch errors within weeks of filing, not after liquidation.

Prior disclosure advantage

If your ACE review reveals that your broker underpaid duties, voluntarily disclosing the error to CBP before it opens a formal inquiry significantly reduces penalty exposure under the framework governing 19 U.S.C. 1592. Acting on your own data before CBP acts on it is the core operational benefit of regular report review.

Common discrepancy patterns importers find

Years of broker reconciliation work reveal a consistent set of error types. Knowing what to look for makes your monthly review faster.

Classification mismatches

The HTS chapter or heading in the ACE data does not match the product specifications in your purchase order or product database. This is the most common error type and the one with the highest duty impact, because a one-chapter shift can move a product from a low general rate to a rate with stacked Section 301 duties.

Missing or wrong overlay codes

For goods subject to additional Section 301 duties, the broker must include the correct Chapter 99 HTS provision. If the overlay code is omitted, CBP may collect the base duty only at liquidation and then issue a bill for the additional duties later, with interest. Conversely, if an exclusion was granted for your specific HTS provision and your broker did not apply it, you overpaid and may be entitled to a refund. See our guide on how tariff exclusions, grants, and refunds work for the mechanics of recovering those overpayments.

Country of origin errors

Origin is sometimes entered based on the country of shipment rather than the country where substantial transformation occurred. A product shipped from a transshipment hub but manufactured elsewhere will carry the wrong origin in ACE if the broker relied on the bill of lading alone.

Missing or incorrect SPI claims

FTA preference claims require both a valid SPI and supporting documentation such as a certificate of origin or importer certification. ACE data shows the SPI claimed; your document file should confirm that the underlying support exists for every claimed preference.

Value discrepancies

Assists (tooling, engineering drawings, or other items you supply to a foreign producer at no charge) must be added to customs value. If your broker does not know about assists, entered values will be systematically understated across every shipment from that supplier.

Duplicate or split lines

System errors or broker workflow issues occasionally result in one shipment line appearing on two entry summaries, or one entry summary splitting a single commercial invoice line into two tariff lines at different rates. Both patterns distort your duty totals and your landed-cost records.

How discrepancies connect to broader tariff exposure

Entry data errors rarely affect just one shipment. A misclassification or wrong country of origin code that goes uncorrected will repeat across every subsequent shipment of the same SKU from the same supplier, compounding the underpayment or overpayment over time.

For importers bringing in goods subject to country-specific additional duties, correct origin coding is especially critical. If a refund later becomes available because of a court ruling or a new exclusion, your ability to recover overpaid duties depends on having clean entry records that accurately reflect what you paid. Our guide on recovering duties after a court ruling explains how that process works and why accurate entry-level records are a prerequisite.

What importers should do

• Set up ACE portal access now if you have not already. Contact CBP through the ACE Secure Data Portal page to establish your account and assign report-user roles to your compliance team.
• Pull and review a line-level entry report monthly. Filter by the prior calendar month, export to a spreadsheet, and reconcile HTS codes, countries of origin, SPIs, and Chapter 99 overlay codes against your product database and purchase orders.
• Build a discrepancy log. Document every mismatch you find, the entry number, the nature of the error, and the corrective action taken. This log is evidence of a functioning compliance program if CBP ever audits your account.
• Act within the liquidation window. If ACE data shows an underpayment, consult with your broker or trade counsel immediately. If it shows an overpayment, confirm the liquidation date and calculate whether you are still inside the 180-day protest window under 19 U.S.C. 1514.
