Customs Exam Fee

A customs exam fee is the charge assessed to an importer when U.S. Customs and Border Protection (CBP) selects a shipment for physical inspection at the port of entry. CBP conducts examinations to verify that the contents of a container match the declared description, to enforce trade compliance, and to screen for contraband, prohibited goods, or national security threats. The exam itself is mandated by the government, but the costs associated with it, including trucking the container to and from the exam site, handling, and facility fees, are borne entirely by the importer.

Types of Customs Exams

CBP conducts several types of examinations, each with different scopes and cost implications. A Tailgate exam (also called a VACIS exam or non-intrusive inspection) involves scanning the sealed container with an X-ray or gamma-ray machine at the port terminal. The container does not need to be opened, and the process is relatively quick. Fees for a tailgate exam typically range from $300 to $500, covering the exam site handling and the imaging process.

A Contraband Enforcement Team (CET) exam requires the container to be opened and a portion of the cargo to be physically inspected. CBP officers pull and examine selected cartons or pallets. CET exams take longer than tailgate scans and involve more handling. Fees range from $500 to $1,000, including the cost of transporting the container to the exam station, unloading and reloading the inspected cargo, and returning the container to the terminal.

An Intensive exam is the most thorough and expensive. CBP may require the entire container to be destuffed (fully unloaded), with every piece of cargo inspected. The container is moved to an off-terminal Centralized Examination Station (CES), where a CBP-approved facility handles the unloading, staging, inspection, and reloading. Intensive exam fees range from $1,500 to $5,000 or more depending on the container size, the type and volume of cargo, and the CES facility’s rate schedule. At busy ports like Los Angeles/Long Beach, intensive exam fees at the higher end of that range are common for 40-foot containers with mixed SKU loads.

Additional Costs Beyond the Exam Fee

The exam fee itself is only part of the total cost. When CBP places a hold on a container, the container cannot be released from the port terminal until the exam is completed and CBP grants clearance. During this period, demurrage charges accrue at the terminal (typically $150 to $350 per day after free time expires). If the exam requires moving the container to a CES, trucking fees for the round trip add $300 to $600. Storage fees at the CES may apply if the container sits there for multiple days waiting for a CBP officer to conduct the inspection.

The total cost of a customs exam, combining the exam fee, demurrage, trucking, and storage, can easily reach $3,000 to $7,000 for a single container. For small and mid-size Amazon sellers importing one or two containers per month, an unexpected exam can consume a significant portion of the shipment’s profit margin.

Why Shipments Get Selected

CBP uses its Automated Targeting System (ATS) to flag shipments for examination based on risk factors. These factors include the product type, the country of origin, the importer’s compliance history, anomalies in the filed documentation, random selection, and intelligence-driven targeting. First-time importers and importers without a consistent entry history face higher selection rates. Products from countries with elevated enforcement focus (China for intellectual property, certain Southeast Asian countries for anti-dumping circumvention) are also more frequently examined.

Joining CBP’s Customs-Trade Partnership Against Terrorism (C-TPAT) program can reduce exam frequency. C-TPAT members receive a lower risk score in the targeting system, resulting in fewer inspections and faster cargo release. The program requires the importer to implement and maintain documented supply chain security practices.

Managing Exam Costs

Importers cannot prevent CBP from selecting their shipments, but they can minimize the financial impact. Filing accurate and detailed customs entries reduces the likelihood of documentation-triggered exams. Ensuring that ISF filings, commercial invoices, and packing lists are consistent and precise eliminates discrepancies that attract scrutiny. Working with an experienced customs broker who responds promptly to CBP inquiries and coordinates exam logistics efficiently shortens the exam timeline and reduces demurrage accumulation.
