Tail Gate Exam

A tail gate exam is the simplest and least intrusive form of physical cargo inspection conducted by U.S. Customs and Border Protection (CBP). The officer opens the rear doors of the container or trailer, visually inspects the cargo visible from the door opening, and may pull a few cartons from the back of the load for examination. The entire contents are not unloaded. The inspection typically takes 30 minutes to 2 hours, depending on the cargo type and the officer’s findings.

Why CBP Orders Examinations

CBP selects shipments for examination based on risk assessment algorithms, random selection, and targeting criteria. Factors that increase the likelihood of an exam include the importer’s compliance history, the country of origin, the commodity type, the declared value relative to typical values for similar goods, and whether the shipment triggered any automated system flags in ACE (Automated Commercial Environment).

New importers face higher examination rates. CBP has no history to evaluate, so the agency examines a larger percentage of their shipments until a compliance track record is established. Importers bringing in goods from countries with high rates of intellectual property violations, drug trafficking, or trade agreement circumvention also see elevated exam rates.

Types of CBP Examinations

The tail gate exam sits at the low end of the intensity spectrum. There are three main exam types, each progressively more disruptive and expensive.

A tail gate exam involves opening the container doors and inspecting from the rear. The examiner checks that the cargo matches the documentation (correct product type, proper markings, consistent quantities) and looks for signs of contraband or undeclared merchandise. The container does not need to be fully unloaded.

An intensive exam (also called a devanning exam) requires unloading some or all of the container’s contents at a CBP examination facility (Centralized Examination Station, or CES). The examiner opens cartons, inspects individual products, verifies counts, and may take samples for lab analysis. This exam takes 1 to 5 business days and costs the importer $500 to $2,500 in CES fees, unloading labor, and re-loading charges.

A VACIS/NII exam uses large-scale X-ray or gamma-ray imaging to scan the entire container without opening it. This is non-intrusive but can lead to a physical exam if the scan reveals anomalies. VACIS exams are typically completed within a few hours and cost $200 to $500.

Cost of a Tail Gate Exam

The tail gate exam itself does not carry a CBP fee. However, the container must be brought to the examination location (either the terminal’s designated exam area or a CES), which involves chassis usage charges and potential drayage fees. If the container was already at the terminal awaiting pickup, the additional cost might be limited to a terminal repositioning fee of $50 to $150. If the container must be drayed to an off-terminal CES, costs increase by $200 to $400 for the round-trip truck movement.

The indirect cost is delay. While the container is held for examination, the importer cannot receive the goods. For FBA sellers with inventory commitments, a 1-to-2-day exam delay can push back the entire inbound shipment timeline, potentially causing stockouts on fast-moving listings.

What Happens After the Exam

If the tail gate exam reveals no issues, CBP releases the container and the importer (or their customs broker) receives a release notification through ACE. The container can then be picked up for delivery to its final destination. If the officer finds discrepancies (wrong product, incorrect country of origin marking, undeclared goods), CBP may order a more intensive examination, issue a penalty, or seize the merchandise depending on the severity of the violation.

Importers should ensure their customs broker is notified immediately when an exam is ordered so the broker can coordinate with the CES, arrange payment for exam fees, and communicate the expected delay to the consignee. Prep centers and warehouses receiving the cargo also need advance notice so they can adjust their dock schedules and labor plans for the delayed arrival.
