White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
Allegations of tariff evasion or customs duty fraud place individuals and companies squarely in the crosshairs of the federal government. These matters are never routine. They threaten not only substantial financial penalties and criminal exposure, but also long-term damage to business operations, licenses, and reputation. For companies engaged in international trade, a single enforcement action can disrupt supply chains, trigger audits across jurisdictions, and jeopardize relationships with banks, partners, and regulators.
At Chapman, Dowling & Mallek, we approach tariff and customs fraud matters with the urgency and discretion they demand—focused on protecting our clients before an investigation escalates and positioning them for the strongest possible outcome if litigation becomes unavoidable.
From a legal perspective, tariff evasion and customs duty fraud defense spans international trade law, customs regulations, and federal criminal statutes. These cases typically involve allegations that an importer intentionally misrepresented goods, values, classifications, or origins to reduce or avoid lawful duties owed to the government.
Effective defense requires far more than surface-level compliance arguments. It demands a strategic command of regulatory frameworks, enforcement practices, and the evidentiary burdens prosecutors must meet. Core defense strategies often include:
Challenging Allegations of Intent
Fraud requires intent. Many customs cases arise from ambiguous regulations, inconsistent guidance, or clerical and valuation disputes—not criminal design. A disciplined defense focuses on demonstrating lawful intent, good-faith compliance efforts, or reasonable interpretations of complex rules.
Disputing the Government’s Factual Narrative
Customs investigations rely heavily on data analysis, documentation, and assumptions drawn from trade patterns. We rigorously examine invoices, shipping records, internal communications, and audit methodologies to expose errors, overreach, or unsupported conclusions.
Interpreting and Applying Complex Regulations
Customs and tariff laws are notoriously technical. Outcomes often hinge on classification rules, valuation methods, or origin determinations that are open to interpretation. Strategic defense frequently rests on demonstrating that the client’s position was legally defensible—even if later challenged by regulators.
Engaging Enforcement Agencies Early
Before criminal charges are filed, skilled counsel can engage directly with enforcement agencies to resolve matters administratively, limit penalties, or prevent escalation. Early advocacy is often decisive.
Litigation and Trial Defense
When civil penalties or criminal charges proceed, defense involves aggressive motion practice, evidentiary challenges, witness examination, and, when necessary, trial advocacy designed to protect both liberty and livelihood.
Tariff and customs enforcement actions arise from a wide range of alleged conduct, including:
Each allegation carries distinct legal and evidentiary challenges—and each demands a tailored defense strategy.
Customs and tariff matters are enforced by multiple federal authorities, often working in parallel:
The consequences of an adverse finding can be severe and long-lasting.
Key federal statutes frequently implicated include:
These provisions give enforcement authorities broad leverage—making early, strategic defense critical.
