Can a customs inspection become a criminal investigation?

by | Jul 14, 2026 | International Trade Litigation

A customs inspection may look routine, but it can change fast. One unexpected finding can put a business under federal scrutiny, disrupt daily operations and threaten years of hard work. Knowing how a routine inspection may escalate into a criminal investigation helps businesses recognize legal risks before they become much harder to control.

When a customs inspection becomes a criminal investigation

Most customs inspections end without any legal action. However, at Florida ports of entry, U.S. Customs and Border Protection (CBP) may expand an inspection or refer a matter for criminal investigation when officers find evidence suggesting fraud, smuggling or other possible violations rather than an isolated administrative error.

Common warning signs include:

  • False or misleading import documents
  • Undeclared currency
  • Restricted or counterfeit goods
  • Controlled substances or other prohibited items
  • Suspected smuggling

Once officers suspect possible criminal activity, they may examine related documents, shipments and statements more closely. Even a single issue can expand the scope of the investigation and increase the legal risks for a business.

What happens after CBP suspects criminal activity?

If CBP suspects a crime, a routine customs inspection can quickly become a federal investigation. Officers may conduct a secondary inspection, ask more questions and review electronic devices under border search authority, record statements, detain individuals or seize goods and other property.

CBP may refer the matter to Homeland Security Investigations (HSI) for further investigation. If investigators believe the evidence supports federal charges, the matter may be referred to the appropriate U.S. Attorney’s Office for possible prosecution. What investigators find early can shape what happens next.

Reducing customs compliance risks

A few compliance mistakes can lead to serious legal problems if they appear intentional. Businesses can reduce that risk by:

  • Maintaining complete and accurate import records
  • Using accurate valuations and tariff classifications
  • Following applicable import restrictions and reporting requirements
  • Reviewing the work of suppliers, brokers and other trade partners
  • Identifying and addressing compliance concerns promptly

Good customs compliance does more than lower legal risk. Strong compliance practices can reduce avoidable disruptions, support accurate reporting and help businesses maintain more reliable trade operations. An experienced attorney can help find legal risks early, improve compliance and guide businesses through complex customs issues with greater confidence.
