The Fiscal and Enforcement Stakes

Tariffs are one of the U.S. government’s most important trade-policy instruments, and they are also a major target for fraud. The scale of the problem is measurable. A review by the U.S. Government Accountability Office (GAO) found that between FY2001 and FY2014, roughly $2.3 billion in antidumping and countervailing duties (AD/CVD) went uncollected, with customs officials expecting most of it never to be recovered. Once shipments clear U.S. borders, recovering unpaid duties is slow, litigious, and often unsuccessful.

At the same time, enforcement has become more visible. U.S. Customs and Border Protection (CBP) reports record-breaking monthly duty collections and rising figures for “duties owed,” reflecting more rigorous audits and frontline reviews. By mid-2025, tariff revenues had reached $136 billion, according to Reuters, with CBP announcing plans to hire thousands of additional officers to expand trade enforcement as a central pillar of U.S. economic security. The implication for all agencies is straightforward: tight verification of trade flows delivers tangible fiscal and policy gains.

How Tariff Evasion Happens

Fraudsters exploit the gap between paper records and real-world movements. They forge or alter Certificates of Origin (COO) to claim preferential tariff rates under free trade agreements, misdeclare HS codes to reduce duty rates, or undervalue invoices to evade revenue collection.

Cargo is often transshipped through third countries to disguise its true origin, with falsified manifests to back the claim. Increasingly, digital deception supports the paperwork: vessels spoof their Automatic Identification System (AIS) positions, falsify port calls, or mask dark activity periods to make fraudulent documents look plausible.

The U.S. Department of the Treasury has recognized this evolution. In its October 2024 sanctions guidance, the Office of Foreign Assets Control (OFAC) warned explicitly about deceptive shipping practices — including AIS spoofing, flag hopping, and complex ownership webs — and directed companies and agencies to verify documentation against vessel behavior as part of a risk-based compliance program.

Why Trade Documents Are So Vulnerable

Documents are easy and cheap to forge digitally, and visual authenticity rarely reflects actual legitimacy. Certificates, manifests, and bills of lading can be fabricated with little cost, while static databases are designed only to confirm names and codes — not to validate whether a vessel actually sailed where the documents claim.

Once cargo clears into the U.S. market, GAO has shown how difficult and low-yield duty recovery becomes. Without corroboration from behavioral data, officers at even the most advanced ports are left with partial intelligence and limited leverage.

AI-Automated Document Validation

Manual checks are too slow for today’s trade volume. That’s where Windward’s AI-Automated Document Validation comes in. The system automatically cross-verifies bills of lading, Certificates of Origin, and manifests against:

Vessel behavior: AIS truth, spoofing detection, port-call verification.
Ownership and flags: Automated resolution of beneficial owners and registries against sanctions and enforcement records.
Container tracking: End-to-end custody validation across transshipment.

For officers, this means a fast-clear for compliant trade and immediate escalation of anomalies. Instead of spending hours reconciling documents against databases, they receive risk-graded results within seconds — aligned with CBP workflows like ACE and ATS. Each case file is stored with voyage traces and timestamps, creating regulator-ready, court-ready packages that strengthen cooperation with ICE-HSI, DOJ, and interagency task forces.

Implementation for U.S. Agencies

Rolling out this approach does not require a full system overhaul; it can begin with targeted pilots. Agencies can start by focusing on high-risk HS codes and lanes — such as textiles, footwear, e-bikes, and certain consumer electronics — that consistently appear in undervaluation and false-origin cases. For the first 90 days, any shipment where the paper trail does not align with behavioral evidence should be flagged for deeper scrutiny.

As programs mature, these checks should be embedded in Automated Commercial Environment (ACE) and Automated Targeting System (ATS) workflows. Behavior-based rules — for example, a vessel showing dark activity within 48 hours before declared loading, or failing to show a verified port call at the claimed origin — can serve as objective escalation triggers. Where discrepancies are clear, duties should be reassessed promptly; where intent is suspected, cases can be escalated for ICE-HSI criminal investigation or DOJ prosecution.

The final stage is to institutionalize auditability. Each decision should be backed by stored voyage traces, timestamps, and ownership resolutions alongside the original documents. This creates regulator-ready and court-ready case files, smoothing interagency cooperation and strengthening prosecutions. The experience of both GAO and CBP shows that structured, auditable enforcement processes (not just better tools) drive recoveries.

Measuring Success

Success should be measured both financially and operationally. Recovered and prevented duties from origin and valuation discrepancies should be benchmarked quarterly against a baseline. Detection efficacy can be tracked as the percentage of flagged entries that yield confirmed mismatches. Cycle times — the median minutes from hit to decision — demonstrate that stronger controls do not paralyze compliant trade. Finally, the broader “portfolio effect” can be measured by tracking total tariff collections against duties owed.

Risk Outlook for U.S. Enforcement

Fraud tactics evolve rapidly. Officers should expect continued spoofing activity around sensitive theaters such as the Middle East, the Gulf of Mexico, and Caribbean transshipment hubs. Free Trade Agreement abuse is likely to grow, with immaculate digital paperwork masking illegitimate transshipment. Shadow fleets and shifting registries tied to Russian and Iranian trade will complicate insurance and liability but will also leave identifiable behavioral fingerprints. Agencies that combine document review with movement data will be the first to detect these schemes and recover the associated revenue.

Bottom Line

Tariff leakage undermines U.S. economic security, deprives the government of revenue, and creates unfair competition for compliant businesses. It is both a policy challenge and a data challenge. Raising tariff rates or widening their scope is only effective if enforcement can separate genuine origin from fiction.

Validating documents against behavior allows agencies to collect more duties, clear legitimate trade more quickly, and litigate less. For CBP, Border Patrol, ICE-HSI, and partner agencies, document validation is the bridge between policy ambition and operational reality, and it is the key to securing America’s revenue base and its borders.
