QUICK ANSWER A customs hold is CBP stopping your shipment from being released until it reviews or inspects it. It can be a quick document check, an X-ray scan, or a full unpack, and it happens for reasons ranging from random selection to a wrong HTS code or another agency's requirements. The goods are not lost, but storage, exam, and demurrage charges accrue while they wait, so the fix is fast response and clean paperwork.
A customs hold turns a routine import into an anxious wait and a growing bill. Most holds are not accusations, they are checks, and many start with a data problem you could have prevented. This guide covers why shipments get held, the types of exams, how long they take, what they cost, and how to get cargo moving again.
Customs holds and exams, defined
A hold is CBP declining to release a shipment until it is satisfied. An exam is the inspection that may follow, from a scan to a full physical unpack. Holds can come from CBP itself or from a partner government agency such as the FDA or USDA that has its own requirements for the goods. Either way, the container stays in CBP custody and cannot be picked up until the hold clears, which is why it interrupts the whole customs clearance timeline.
Why shipments get held or examined
The reasons cluster into a handful of categories, and most are avoidable.
Why shipments get held
| Reason | What triggers it |
|---|---|
| Random selection | Routine CBP sampling, no red flag needed |
| Risk targeting | Commodity, origin, or importer risk profile |
| Data problems | A wrong HTS code, vague description, or value mismatch |
| ISF issues | A late, missing, or inaccurate ISF filing |
| Agency (PGA) requirements | FDA, USDA, EPA, CPSC, or other agency rules for the goods |
The data-driven holds are the ones you control, and they trace straight back to the HTS code, the product description, and the ISF filing.
The types of customs exams
If a hold escalates to an exam, the type determines the cost and the delay.
The three types of customs exam
| Exam | What happens | Relative delay |
|---|---|---|
| VACIS / NII | Non-intrusive X-ray scan of the container | Shortest, hours to days |
| Tailgate | Doors opened, visible cargo inspected | Moderate |
| Intensive | Container moved to a station and fully unpacked | Longest, up to weeks |
The intensive exam is the expensive one: the container is trucked to a Centralized Examination Station, unloaded, inspected, and repacked, and you pay for every step of it.
How long a hold or exam takes
A non-intrusive scan can clear in a day or two. A tailgate exam adds a few days. An intensive exam can run one to three weeks or more, because the container has to queue for the examination station, get unpacked and inspected, and be repacked and returned. The clock is worse when the hold lands during a congested period, and none of it moves faster by calling to complain.
What a hold or exam costs
The exam itself carries fees, and for an intensive exam there are drayage-to-station, unloading, and repacking charges on top. But the largest cost is usually not the exam fee.
TAKEAWAY The real cost of a customs exam is rarely the exam fee. It is the demurrage and per-diem stacking up while the container sits in the queue and at the examination station. A one-week intensive exam can generate more in port and equipment charges than the inspection itself, which is why speed of response, not the exam fee, is what protects the budget.
What to do if your shipment is held
Move fast and give CBP what it needs. Find out the exact hold type and reason through your broker, provide any requested documents immediately, and if an agency hold is involved, satisfy that agency's requirement. There is no shortcut past the exam itself, but a shipment that answers every question the first time clears faster than one that dribbles out documents over days. The goal is to remove every reason for the container to keep waiting.
How to avoid customs holds
You cannot avoid random selection, but you can avoid the holds you cause. File a complete, accurate ISF on time. Use the correct HTS code and a specific product description, not a vague one. Make sure the invoice value and the packing list agree. Meet any partner-agency requirement before the goods arrive. Consistent data, filed ahead of arrival, is what keeps a routine review from turning into a document hold and a mounting port bill.
How Platton helps you clear a hold
A hold is a race between the clock and the paperwork. Platton runs the shipment so the paperwork is already ready and the container moves the moment it clears.
Clean data that avoids self-inflicted holds
Your assigned licenced customs broker files an accurate ISF and a correct classification through customs compliance review, so the avoidable, data-driven holds do not happen in the first place.
Fast, complete response on a real hold
When CBP or an agency does hold a shipment, customs broker identify the reason and supply the documents in one pass, so the container is not waiting on us.
Moved the moment it releases
Clearance and drayage run on the same shipment file, so the container comes off the terminal, or back from the exam station, as soon as it releases, before more charges stack up.
The cost kept visible
Exam and demurrage exposure are flagged as a risk on the quote, so a hold is a managed event with a known cost, not a surprise on your landed cost.

Common Questions About Customs Holds
Why is my shipment held in customs?
Usually for one of a few reasons: random CBP selection, risk targeting based on the commodity or origin, a data problem like a wrong HTS code or a value mismatch, an ISF issue, or a partner agency's requirement for the goods. Random holds you cannot prevent, but the data-driven ones are avoidable. Your broker can tell you the exact hold type and what CBP is waiting for.
How long does a customs exam take?
It depends on the type. A non-intrusive X-ray scan can clear in a day or two, a tailgate exam adds a few days, and an intensive exam can take one to three weeks or more because the container must queue for an examination station, be unpacked, inspected, and repacked. Congested periods stretch all of these, and the delay is largely outside your control once the exam is ordered.
How much does a customs exam cost?
The exam carries fees, and an intensive exam adds drayage to the examination station, unloading, and repacking charges. The bigger cost is usually the demurrage and per-diem accruing while the container waits in the queue and at the station. A single intensive exam can generate more in port and equipment charges than the inspection fee itself, so responding quickly is what limits the total.
What should I do if my shipment is on a customs hold?
Find out the exact hold type and reason through your broker, provide any requested documents immediately, and satisfy any partner-agency requirement involved. You cannot skip the exam, but answering every question in one pass clears the hold faster than supplying documents piecemeal. The aim is to leave CBP no remaining reason to keep the container.
How do I avoid customs holds?
File a complete, accurate ISF on time, use the correct HTS code with a specific product description, keep the invoice value and packing list consistent, and meet any agency requirement before arrival. You cannot avoid random selection, but accurate data filed ahead of arrival prevents the self-inflicted holds, which are the majority. Accurate paperwork is the single biggest factor in staying out of a document hold.
