How to Choose the Right Customs Broker: 5 Questions That Protect Your Import Business

By Jason Kim · Branch Manager · 15 years in freight forwarding · Los Angeles · Frankfurt · Chicago

Every importer who brings goods into the United States needs a licensed customs broker. Not every importer knows how to choose a good one.

In 15 years of managing freight operations across Los Angeles, Frankfurt, and Chicago, I have worked alongside hundreds of customs brokers. I have seen brokers save clients tens of thousands of dollars through sharp classification work and proactive compliance management. I have also seen brokers cost clients far more than their fees through careless entry preparation, missed deadlines, and compliance failures that triggered CBP audits lasting years.

The difference between the two is not always visible on a rate sheet. It shows up in the details — the questions they ask before they start, the systems they use, and how they respond when something goes wrong.

This guide gives you the five questions that separate the customs brokers worth trusting from the ones who will quietly erode your import margins.

What a Customs Broker Actually Does

A licensed customs broker is a private individual or firm licensed by U.S. Customs and Border Protection to act as an agent for importers in the transaction of their customs business. The operative word is licensed. Customs brokerage in the United States is a regulated profession — brokers must pass a rigorous CBP examination and maintain their license through continuing education and compliance.

What a customs broker does on your behalf includes preparing and filing your customs entry in ACE — the Automated Commercial Environment — paying duties and fees to CBP on your behalf, managing your ISF filings, coordinating with CBP during exams or queries, and advising you on classification, valuation, and trade program eligibility.

What a customs broker does not do is assume your legal liability. The importer of record — you — remains legally responsible for the accuracy of every customs declaration filed in your name, regardless of who prepared it. This is the most important thing to understand before you sign a Power of Attorney with any broker. You are authorizing them to act on your behalf. You are not transferring your compliance responsibility to them.

The License — The First Thing to Verify

Before any other question, confirm that the customs broker you are considering holds a valid CBP license. This is not a formality. Unlicensed individuals and companies offering customs clearance services do exist — operating under arrangements with licensed brokers or, in some cases, operating illegally.

Verify a broker's license directly through CBP's licensed broker search tool, available at cbp.gov. Search by name or license number and confirm the license is active and in good standing. This takes two minutes and should be the first step in any broker evaluation.

Also confirm whether the broker holds a license in their own name or operates under a parent company's license. Individual broker licenses and company licenses operate differently, and understanding which one covers your account matters if disputes arise.

The 5 Questions to Ask Before Signing a Power of Attorney

A Power of Attorney authorizes your customs broker to act as your legal agent before CBP. It is a significant legal document. Before you sign one, ask these five questions — and evaluate the quality of the answers as carefully as the answers themselves.

Question 1: What experience do you have with my specific product category and HTS codes?

Customs brokerage is not a uniform service. A broker who specializes in automotive parts may have limited experience with FDA-regulated food products. A broker who primarily handles ocean freight FCL shipments may not have strong systems for air freight clearance or express courier entries.

Ask specifically about experience with your HTS chapters — the two-digit chapter of your Harmonized Tariff Schedule code groups products into categories. A broker who regularly files entries in your HTS chapter will have familiarity with CBP's focus areas, common classification disputes, and applicable trade programs that a generalist may miss.

The right answer is specific. "We handle a lot of Chapter 84 entries for machinery clients and have resolved two binding ruling requests in that chapter in the past year" is a good answer. "We handle all types of cargo" is not.

Question 2: Who will actually be handling my account — and what are their qualifications?

This is the question most importers forget to ask — and one of the most important. Larger brokerage firms may have impressive credentials and experienced leadership, but your day-to-day account may be handled by a junior entry writer with limited experience.

Ask for the name and qualifications of the specific person or team who will prepare your entries. Ask whether they are a licensed customs broker themselves or an unlicensed entry writer working under a broker's supervision. Both are legal, but the distinction matters for the level of expertise reviewing your compliance.

Ask about staff turnover. High turnover at a brokerage firm means institutional knowledge about your account — your suppliers, your products, your classification history — walks out the door regularly. Continuity of account management is underrated and worth asking about directly.

Question 3: How do you handle HTS classification — and what is your process for staying current with tariff changes?

HTS classification is the most consequential technical task a customs broker performs for you. An incorrect classification can result in duty overpayments, duty underpayments that create CBP liability, missed FTA eligibility, or Section 301 tariff exposure you were not aware of.

Ask the broker to walk you through their classification process. Do they research each new product independently using the CBP CROSS database and the HTS schedule notes? Do they consult with a trade attorney on complex classifications? Do they proactively monitor Federal Register notices and CBP guidance for changes that affect your product categories?

In 2026, with ongoing tariff activity and Section 301 exclusion processes, a broker who is not actively monitoring the regulatory landscape for your HTS codes is a compliance risk, not a compliance resource.

Also ask whether they will provide you with written classification opinions for your key products. A broker who is confident in their classification work will put it in writing. A broker who is vague about this is telling you something important.

Question 4: How do you communicate with clients — and what does your exception management process look like?

The quality of a customs broker's communication is most visible when something goes wrong. A CBP hold, an ISF flag, a CF-28 request for information — these are the moments that reveal whether your broker is a reactive order-taker or a proactive compliance partner.

Ask specifically: if my shipment is placed on a CBP exam hold, what happens next? Who contacts me, within what timeframe, with what information? What do you need from me and how quickly? What is your process for responding to CBP queries?

The right answer describes a clear, systematic process with defined response times and specific points of contact. "We'll reach out to you" is not a process. "Our exam coordinator contacts the importer within two hours of notification with the exam type, estimated timeline, and required documentation checklist" is a process.

Also ask about their technology. In 2026, a customs broker without a client portal offering real-time entry status, document access, and shipment tracking is operating below the standard you should expect. You should never have to call your broker to ask where your clearance stands.

Question 5: Can I see a sample invoice and a breakdown of all fees I will be charged?

Customs broker fee structures can be complex, and the difference between the quoted entry fee and the final invoice can be significant. Understanding every fee before you start is not just good financial practice — it is a test of the broker's transparency.

A straightforward customs brokerage invoice for a standard ocean freight entry typically includes the customs entry fee, the ISF filing fee, any exam fees if applicable, the Harbor Maintenance Tax, the Merchandise Processing Fee, and potentially document handling fees. Some brokers also charge for telex release processing, AMS filing, bonding fees, and various administrative charges.

Ask for a complete fee schedule in writing before you sign anything. Ask specifically whether there are any fees not on the schedule that might appear on your invoices. A transparent broker will walk you through every line item without hesitation. A broker who is vague about fees, or who tells you fees vary and are hard to predict, is signaling that your invoices will contain surprises.

Also ask about their bond requirements. A continuous bond covers all your entries throughout the year and is typically more cost-effective for regular importers than a single-entry bond per shipment. If the broker recommends single-entry bonds for a regular importing program, ask why.

Red Flags That Signal the Wrong Broker

Beyond the five questions above, watch for these signals during your evaluation process.

They cannot explain your classification clearly. If your broker cannot tell you why your product is classified under a specific HTS code — not just what the code is, but why — they do not fully understand what they filed. Classification decisions should be explainable in plain language.

They discourage you from asking questions. A customs broker who responds to your compliance questions with impatience, vague reassurances, or suggestions that you do not need to worry about the details is not a compliance partner. You are the importer of record. You have every right — and a legal responsibility — to understand your customs declarations.

They have never filed a protest or prior disclosure. A customs protest is a legal challenge to CBP's liquidation of an entry. A prior disclosure is a voluntary self-report of a customs violation that significantly reduces penalties. If your broker has never navigated either process, they lack experience with the more complex compliance situations that will eventually arise in any active import program.

They cannot provide client references in your industry. A broker who is reluctant to provide references from current clients with similar import profiles is telling you something. References in your specific product category or trade lane are the most valuable — ask for them specifically.

Their technology is outdated. A broker still communicating primarily by email attachments, without a client portal or automated milestone notifications, is operating on infrastructure that increases the risk of errors and delays. The technology your broker uses affects your compliance directly.

Evaluating Performance Once You Start

Choosing a customs broker is not a one-time decision. Once you begin working with a broker, establish a quarterly performance review process. Track the metrics that matter: entry accuracy rate, average clearance time on your primary lanes, number of CBP queries or holds, invoice accuracy against quoted fees, and responsiveness during exceptions.

Set clear expectations at the start of the relationship — in writing. Define what good performance looks like for your account: acceptable clearance timeframes, required communication windows during holds, classification review timelines for new products. A professional customs broker will welcome this clarity. A broker who resists it is signaling that they prefer to operate without accountability.

The right customs broker is not just a filing service. They are a compliance advisor who helps you import more accurately, more efficiently, and with lower regulatory risk over time. That relationship has real financial value — and it starts with the five questions above.

A Note on Power of Attorney

Before you sign a customs Power of Attorney, read it. The POA authorizes your broker to act as your legal agent before CBP and may include provisions about liability, data sharing, and fee disputes. Have your trade attorney review it if you are unsure about any provisions.

A POA can be revoked at any time — it does not lock you into a permanent relationship. However, revoking a POA while shipments are in transit requires careful coordination to ensure continuity of clearance. Plan any broker transitions during a quiet period in your shipping calendar, not during peak season.

The Bottom Line

Your customs broker files declarations in your name, with your legal liability attached. The entry fee you pay them is not just for a service — it is for expertise, accuracy, and compliance protection. Choose accordingly.

The five questions in this guide will not guarantee you find the perfect broker on the first try. But they will eliminate the wrong ones quickly and give you a framework for evaluating the ones worth a second conversation.

In 15 years of freight forwarding, the importers who had the smoothest customs experience were the ones who treated their customs broker relationship as seriously as any other key vendor relationship. They asked hard questions upfront, set clear expectations, and held their brokers accountable. That discipline paid dividends every time a shipment hit turbulence.
