Exam types, from imaging to full devanning
CBP concentrates its inspections on shipments its targeting identifies as higher risk, and it uses non-intrusive inspection technology to examine cargo without slowing trade. The type of exam decides how long a container is tied up. Imaging is usually the quickest, while an intensive exam means moving the box to an exam station and unloading it. Other agencies can require their own inspections as well.
- Non-intrusive imaging, often at or near the terminal
- Tailgate exam: officers open the doors and inspect near the back
- Intensive exam: the container goes to a CES and is unloaded
The importer's bill for a government exam
CBP says it does not charge for cargo exams in normal operations, but the importer bears the costs around them. Under 19 U.S.C. 1467, CBP may examine any imported shipment, and its regulations make the importer responsible for preparing goods for examination. In practice that means drayage to and from the exam site, the station's unloading and reloading fees, and storage while the cargo waits. Demurrage or detention can keep running too, depending on the tariff.
What an exam looks like in tracking data
Carrier milestones rarely mention an exam. The usual pattern is a container that discharged on time, shows a customs hold, and then sits or gates out to an exam station, with a long gap before its delivery move. The broker receives CBP's exam notices and can confirm what is happening. Because exams stretch the time between discharge and delivery, recheck the last free day and the trucker's plan once an exam is confirmed.
Example
CBP selects MSCU1234566 for an intensive exam, so it is drayed to a Centralized Examination Station, devanned, inspected and reloaded before it can be delivered, adding days and charges.

Questions
What does CBP Exam mean?
A CBP exam is an inspection of imported cargo by Customs and Border Protection to confirm it complies with U.S. law. Exams range from non-intrusive imaging of the container to a full unload at a Centralized Examination Station.
How long does a CBP exam take?
There is no standard time. It depends on the exam type, the port's backlog, the exam station's schedule and what officers find. The broker usually has the best local estimate.
Why was my container selected for an exam?
CBP does not usually explain individual selections. Exams can follow from risk targeting, data problems such as a late or inaccurate ISF, or other agencies' requirements. A clean filing history helps but does not rule exams out.
