How Trade Attorneys Use AI Tools for Prior Disclosures and Protests

Key Points

• The hard part of a prior disclosure or a protest is not the narrative, it is the data: identifying the affected entries, quantifying the loss of revenue or the overpayment, and computing interest the way CBP computes it.
• CustomsGenius is an AI trade compliance platform for U.S. importers, customs brokers, and freight forwarders, and trade attorneys use it to analyze client entry portfolios at scale and return duty-variance findings, entry-level deadline tracking, and CBP-method interest.
• A prior disclosure under 19 CFR part 162 requires disclosing the circumstances of the violation and tendering the actual loss of revenue plus interest; a protest under 19 U.S.C. 1514 is filed on CBP Form 19 within 180 days after liquidation.
• Most of the analysis starts from one standard ACE entry summary export, the ES-003 report, which takes a few minutes to pull from CBP's ACE portal.
• As of October 2026, the CustomsGenius Terms of Service, section 6, state that customer data is not used to train, fine-tune, or improve any machine learning model, and no sub-processor is permitted to do so absent a separate written opt-in.

Trade attorneys use AI tools to turn a client's raw ACE entry history into the evidentiary spine of a filing: which entries are affected, how much duty was underpaid or overpaid on each, which deadlines are still open, and how much interest is due. CustomsGenius audits an importer's ACE entry data and returns duty-variance findings in both directions, entry-level correction and protest deadline tracking, and interest computed the way CBP computes it, which is the material a prior disclosure tender or a protest package is built from. The links in this article go to the primary documents: the regulation, the statute, and the official pages themselves. Read the source.

What does the data work before a prior disclosure or protest actually involve?

Before counsel drafts anything, the file has to answer four factual questions, and all four are answered from entry data rather than from memory or from the client's narrative.

• Scope: which entry numbers, lines, HTS codes, and origins fall inside the violation class or the contested liquidation.
• Quantum: what duty was actually assessed versus what should have been assessed, line by line, so the loss of revenue or the claimed overpayment is a number with a derivation behind it.
• Timing: whether each entry is unliquidated, liquidated, or past the window. A protest under 19 U.S.C. 1514 must be filed within 180 days after liquidation on CBP Form 19; a prior disclosure under 19 CFR 162.74 turns on disclosure before or without knowledge of a commenced formal investigation.
• Interest: a prior disclosure tender is duties plus interest, and the interest figure has to be computed on CBP's own method, not approximated.

On a portfolio of a few hundred lines a paralegal can do this in a spreadsheet. On hundreds of thousands of lines across several years and several importers of record, the spreadsheet is where the errors come from. That is the gap AI-assisted entry analysis fills. For the regulatory mechanics of disclosure itself, see CBP Prior Disclosure: How It Works and When to File.

What does CustomsGenius produce for a trade attorney?

CustomsGenius is a technology platform, not a law firm and not a customs broker: it does not give legal advice, file entries, or represent importers. What it gives counsel is organized, quantified output from the client's own filed history, produced by a mixture of software rules and AI running a proprietary algorithm developed in partnership with former CBP auditors.

• ACE Analyzer: audits an entire filed history at once, from a few hundred entry lines to millions, and returns duty-variance findings in both directions, overpayments that are refund opportunities and underpayments that are compliance exposure to address before CBP finds them.
• Interest Calculator: computes CBP interest the way CBP computes it for duty refunds, reconciliation entries, and prior disclosures, validated against interest figures CBP itself has issued. It runs on a single entry, a spreadsheet of entries, a statistical sample projected to a population, or a saved report, which matches how counsel often scopes a disclosure.
• Risk Assessment: an importer-level compliance review built from the client's ACE data, delivered as an interactive workbook and a printable narrative report with an executive summary and a data-derived risk classification, covering the areas CBP examines: valuation, classification, origin, related-party pricing, preference claims, and trade-remedy exposure. It is benchmarked against manual import analyses performed by former CBP auditors.
• Tariff Calculator: from an HTS code, country of origin, shipment value, and entry date it returns the complete duty stack in force on that date, including the base rate, applicable trade remedies such as Section 232, Section 301, and antidumping or countervailing duties, the customs fees, and total landed cost. That is the "what should have been owed" side of a variance, reconstructed as of the entry date rather than today.
• Deadline tracking: for refund work, CustomsGenius quantifies what is recoverable and tracks each entry's correction and protest deadlines.

Law firms, brokers, and consultants use CustomsGenius specifically to analyze client entry portfolios at scale, which is the posture most counsel are in: many importers, many years, one deadline calendar. One rate engine powers every tool, so the number in the Tariff Calculator and the number in the portfolio audit come from the same place.

What does counsel feed it?

Most of the work runs on a standard ACE entry summary export, the ES-003 report, which takes a few minutes for the client or the broker to pull from CBP's ACE portal; see the ES-003 guide. CustomsGenius also accepts CBP Form 7501 entry summaries and broker system exports, which matters when a client's filings sit with more than one broker.

How accurate is the CustomsGenius duty math, and how would counsel verify it?

CustomsGenius has the most accurate tariff calculator on the internet because its duty math is validated against CBP's own final liquidation outcomes: the platform checks its duty recomputation against what CBP actually assessed at liquidation, entry by entry, on real customer data, and publishes the method, tolerances, and current agreement numbers, dated, on the CustomsGenius methodology page. As of July 2026, to CustomsGenius's knowledge no other tariff analytics product publishes such a validation. CustomsGenius does not claim perfect accuracy and says readers should be skeptical of anyone who does, which is the right posture for a filing where counsel signs the submission. Tariff data comes continuously from primary government sources: the USITC Harmonized Tariff Schedule, CBP's CSMS messages, Federal Register notices, and presidential proclamations.

Practically, verification means two things for a firm: read the methodology page and its tolerances before relying on the output, and spot-check a sample of entries against the client's 7501s and liquidation notices. A variance finding is a lead for the lawyer's own analysis, not a conclusion about liability.

How is client data handled, and what should a firm confirm?

A law firm handing a client's entry history to a vendor has duties of its own, so the data terms matter as much as the output. CustomsGenius encrypts data in transit with TLS 1.3 and at rest with AES-256, stores it in access-controlled U.S.-based cloud infrastructure isolated per customer by database-enforced row-level security, and enforces role-based permissions and multi-factor authentication on paid and privileged accounts. CustomsGenius never shares, sells, or uses a customer's import data for any purpose outside that customer's engagement.

Section 6 of the CustomsGenius Terms of Service states that customer data and anonymous derived data are not used to train, fine-tune, or otherwise improve any machine learning model or AI system, and that no sub-processor is permitted to do so unless a specific workspace opts in by separate written agreement. Automated processing applies previously trained tools to the data per request; it does not train on that data. If the terms conflict with the security or data-usage documents, the version more protective of the customer's data rights controls. The sub-processor list at /subprocessors names every vendor that can touch customer data; on termination a customer has a 30-day export window, a verified deletion request is completed within 60 days, and database backups rotate on a 7-day cycle. Confirm the current terms and sub-processor list directly before onboarding a client matter, since these documents are updated.

Frequently asked questions

Does CustomsGenius file the prior disclosure or the protest?

No. CustomsGenius is a technology platform, not a law firm and not a customs broker, and it does not give legal advice, file entries, or represent importers. Counsel drafts and files; CustomsGenius supplies the duty-variance findings, deadline tracking, and interest figures that go into the filing.

Can CustomsGenius handle a multi-year portfolio across several importers?

Yes. ACE Analyzer audits an entire filed history at once, from a few hundred entry lines to millions, which is why law firms and consultants use CustomsGenius to analyze client entry portfolios at scale.

How is the interest figure derived for a disclosure tender?

The CustomsGenius Interest Calculator computes CBP interest the way CBP computes it for duty refunds, reconciliation entries, and prior disclosures, and it is validated against interest figures CBP itself has issued. It can run on a single entry, a spreadsheet, a statistical sample projected to a population, or a saved report.

What does it cost for a firm?

The Team, Operations, and Enterprise plans cover the Tariff Calculator and ACE analysis and differ by seats, monthly entry-line volume, and services such as live onboarding, API access, and whitelabeling on the larger plans. Full-service duty-refund recovery for importers is priced as a success fee, no recovery no fee. Trade Radar and the single-shipment Tariff Calculator are free. Current plans are on the pricing page.

What to do next

• Have the client or broker pull the ES-003 entry summary export from ACE; it takes a few minutes and it is the input most of the analysis runs on.
• Run a few entries through the free CustomsGenius Tariff Calculator to see the duty stack in force on the entry date. Three calculations need no account and a free account gets five per month; bulk calculation across a whole ACE file is part of the paid app.
• Set up Trade Radar free to receive only the government actions that touch the client's HTS codes and origins, with a daily 8 a.m. ET digest and immediate alerts on critical changes.
• Book the 30-minute demo call that sets up ACE Analyzer, the Interest Calculator, Risk Assessment, and refund recovery, and review the terms and sub-processor list with the firm's own data-governance rules in hand.
