CBP Customs Examination: What Happens When Your Electronics Get Pulled

Your container just arrived in Los Angeles. Your freight forwarder sends you a message: CBP has put a hold on the shipment for examination. Now what?

This happens to electronics importers from China regularly. It’s not necessarily a sign something is wrong. But it costs you time and money either way. Here’s what to expect.

The Four Types of CBP Exams

CBP doesn’t do one kind of exam. They have several options depending on how closely they want to look at your cargo.

Document Review

The least invasive option. CBP reviews your paperwork, not your physical goods. They’re checking your commercial invoice, bill of lading, packing list, and entry documents for consistency and accuracy.

No physical inspection happens. Your cargo doesn’t move to a different location. But your release gets delayed while CBP reviews the documents, typically 2 to 5 business days.

Document reviews are common for new importers or when the documentation raises questions. If your invoice looks inconsistent with the declared value or the product descriptions don’t match the HTS codes, this is often what triggers it.

X-Ray Exam

CBP scans your container with a non-intrusive imaging system. They’re looking for undeclared cargo, contraband, and gross misrepresentation of the shipment contents.

The scanner can’t verify detailed product specifications, but it can tell if you declared 500 boxes of phone accessories and the container looks like it has 2,000 boxes. Or if there’s a suspicious structure inside the cargo.

X-ray exams typically cost $200 to $600 and add 1 to 2 days to your release timeline. The fee comes to you as the importer.

Tailgate Exam

CBP opens the container at the port and inspects the cargo at the container door. They’re looking at what’s actually in there, spot-checking boxes, and checking markings without fully unloading everything.

It’s less thorough than a full intensive exam but more involved than an x-ray. Cost is typically $300 to $800. Timeline adds 2 to 4 days depending on port volume and CBP staffing.

CET/Intensive Exam

This is the one that hurts. Full physical examination of your cargo at a Container Examination Station (CES). Your container gets trucked from the port to the CES, unloaded, inspected thoroughly, and reloaded.

CBP inspectors go through the boxes. They’re checking markings, certifications, country of origin labels, and product safety documentation. They can test equipment if they have concerns about what it actually is.

The costs add up fast:

The examination fee itself runs $800 to $2,500. Then there’s the dray fee to move your container from the port to the CES, which runs $400 to $900 depending on distance. Cargo Freight Station handling fees add another $200 to $600. If the exam runs into overtime or takes multiple days, those charges compound.

All in, an intensive exam can easily cost you $1,500 to $4,000 out of pocket, plus the time delay. Timeline is typically 5 to 15 business days. During busy season at a major port, it can run longer.

You pay all of this even if CBP finds nothing wrong and releases your goods clean.

What Triggers an Exam

CBP doesn’t publish their selection criteria, but the patterns are well-established.

New importers get more scrutiny. If this is your first or second entry, your profile is unproven. CBP has no track record on you. Expect higher exam rates until you build a clean history.

China-origin electronics flag at higher rates than many other categories. Section 301 tariffs created massive enforcement pressure around electronics from China, specifically around tariff evasion and transshipment. CBP watches this closely.

Certain HTS codes see more exams than others. Consumer electronics, semiconductors, and anything that’s been the subject of AD/CVD (antidumping/countervailing duties) cases or Section 301 disputes gets more attention.

Prior violations, holds, or enforcement actions against you or your supplier create a flag in CBP’s systems.

Random selection. CBP’s targeting algorithms include a random element. Sometimes there’s no particular reason. You just got picked.

Intelligence from other agencies or tips about specific suppliers or shipment routes can trigger targeted holds on your goods even if your paperwork is clean.

Who Pays for the Examination

You do. The importer always pays for exam costs.

This is one of the more unpleasant surprises for first-time importers. You haven’t done anything wrong, CBP found nothing wrong, but you still owe $2,000 for the exam they ran on your shipment.

That’s just how it works. Budget for exam costs as a real possibility on every shipment, especially in the first year of importing and especially for electronics from China.

Some freight forwarders will front the exam fees and bill you afterward. Others require you to pay before the container is released from the CES. Get clear on your forwarder’s policy before you’re in this situation.

What CBP Is Actually Looking For

When inspectors examine your electronics shipment, they’re looking at several things.

FCC markings are a major focus. Consumer electronics that require FCC authorization need to display the FCC ID on the product and on the packaging. If your products are supposed to have FCC markings and they don’t, CBP will note it and the shipment may be detained for further review or refused entry.

Country of origin markings. Every article imported into the US must be marked with the country of origin in a conspicuous location. For electronics, that typically means “Made in China” or “Product of China” marked clearly on the product itself and on the retail packaging. Missing or insufficient origin marking triggers a discrepancy.

Product safety certifications. Depending on what you’re importing, inspectors may look for UL marks, CE marks (for verification purposes), or documentation showing compliance with relevant safety standards. This is particularly common for power supplies, chargers, batteries, and anything that plugs into a wall.

Mislabeled or misclassified goods. If your invoice says “phone accessories” but the boxes are full of completed smartphones, that’s a classification problem with duty and regulatory consequences. Inspectors cross-check what’s in the boxes against what’s on the entry.

Counterfeit goods. CBP actively enforces intellectual property rights. Shipments that appear to contain goods infringing US trademarks or patents can be seized. Electronics with fake brand markings, unauthorized replicas of name-brand products, or goods with counterfeit certifications marks all create serious problems.

How to Work Through an Exam Notice

When you get an exam notice, the first call is to your customs broker. Don’t contact CBP directly unless you don’t have a broker.

Your broker will tell you what type of exam was ordered, what documents CBP has requested (if it’s a document review), and what the expected timeline looks like. For intensive exams, your broker coordinates the container movement to the CES.

Provide any requested documents quickly. Document reviews especially can move fast if you turn around the paperwork promptly. Stalling doesn’t help you.

Don’t try to negotiate with CBP or explain why the exam is inconvenient. They don’t factor that in. Cooperate fully through your broker and wait.

If CBP finds a problem, your broker will tell you what the issue is and what your options are. That might mean paying a fine, addressing a marking issue, having goods re-exported, or in serious cases, seizure. Each situation is different.

Exam Types and What They Mean for Your Timeline

A document review that goes smoothly adds 2 to 5 business days to your release. If CBP asks for additional documentation and you provide it promptly, you’re looking at the lower end.

An x-ray exam adds 1 to 2 days if nothing unusual shows up in the scan.

A tailgate exam adds 2 to 4 days.

An intensive exam is the wildcard. The CES scheduling, container dray, and physical inspection process means you’re rarely looking at less than 5 business days, and 10 to 15 days is common. At major ports during peak season, delays beyond 15 days happen.

All of these timelines assume no problems are found. If CBP finds issues that need resolution, you can add more time on top of the exam itself.

Container Examination Stations vs. Port Exams

Not all exams happen at the port. Container Examination Stations are CBP-approved facilities where containers are moved for more thorough inspection. These are typically operated by private logistics companies under CBP oversight.

The difference matters because moving a container to a CES costs money (that dray fee), adds time, and means your goods go through additional handling. There’s a higher risk of minor damage when cargo is unloaded and reloaded at a CES compared to a tailgate exam at the port.

When your broker says your shipment was sent to a CES, that’s the signal you’re in an intensive exam situation.

How to Reduce Your Exam Risk

You can’t eliminate the possibility of an exam. But you can reduce the odds.

Clean documentation is your first line. Your commercial invoice, packing list, and bill of lading should all tell exactly the same story. Product descriptions should match the HTS codes. Values should be realistic for the products. Discrepancies between documents are a flag.

FCC marks on the product and packaging before shipment. Don’t import electronics that need FCC authorization without confirmed authorization in place. Have the FCC ID displayed correctly on the product itself and on each retail box.

Accurate HTS classification. Work with your broker on the right codes. Intentional misclassification to get lower duty rates is fraud, and CBP is good at catching it on electronics from China given the amount of attention the category gets.

Build a clean import record. Each clean entry improves your profile. After a year of clean entries, you’ll typically see lower exam rates than you did in your first few shipments.

Avoid suppliers who’ve had enforcement actions. If a supplier has been flagged for IP violations or counterfeit goods, shipments from them carry higher risk.

If You Realize You Made an Error

If you discover you made a mistake on an entry and want to fix it before CBP finds it, the prior disclosure process is your option. Prior disclosure can significantly reduce penalties compared to CBP discovering the same error on their own.

This is a formal process and it’s worth talking to a customs attorney before doing it. The key is that it has to happen before CBP has already initiated an investigation or examination that would have revealed the issue. Timing matters.

Don’t ignore errors hoping CBP won’t notice. CBP can liquidate entries and assess additional duties for up to 4 years after the original entry. The electronics import space is too scrutinized for this to be a good strategy.
