How to Find a Customs Broker

7 Things to Look For in a Customs Broker

There are approximately 14,454 licensed customs brokers in the United States. Most can file a customs entry. But the difference between a broker who merely files entries and one who actively protects your supply chain is enormous — measured in penalties avoided, duties saved, and shipments cleared on time rather than stuck at the port.

Here are the seven criteria that matter most when choosing a customs broker, based on what separates the best brokers from the rest.

1. Verify CBP License

This is the non-negotiable starting point. Every customs broker in the United States must hold a valid license issued by U.S. Customs and Border Protection. Operating as an unlicensed customs broker is a federal offense, and using one exposes you to significant compliance risk.

You can verify a broker's license through CBP's online broker lookup tool. Ask any broker you are considering to provide their license number and verify it directly with CBP. Also check whether the broker has a national permit, which allows them to file entries at any U.S. port, or only a district permit, which limits them to specific ports. If you import through multiple ports, you need a broker with national coverage.

2. Check Industry Specialization

Not all customs brokers handle all product categories equally. The regulatory requirements for importing food (FDA), automotive parts (DOT, EPA), electronics (FCC, CPSC), textiles (quota management, fiber content labeling), chemicals (EPA, TSCA), and consumer goods (CPSC) are vastly different. A broker who excels at clearing consumer electronics may have limited experience with FDA-regulated food imports.

When evaluating a broker's specialization, ask specific questions:

• What percentage of your entries involve my product category?
• Which partner government agencies (PGAs) do you regularly file with?
• Can you walk me through how you would classify my specific product?
• Have you handled products subject to the same special tariffs that affect mine (Section 301, Section 232, AD/CVD)?
• Can you provide references from importers in my industry?

A broker who cannot answer these questions confidently and specifically probably does not have the depth of experience your products require. General competence is not enough — you need a broker who understands the specific regulations, classifications, and compliance risks that apply to your goods.

3. Compare Pricing Transparency

The customs brokerage industry has historically operated with opaque pricing. Many brokers quote an attractive per-entry fee but then add surcharges for every additional service: ISF filing ($25–$75), PGA submissions ($25–$50 per agency), exam coordination ($50–$150), duty disbursement fees (percentage of duties paid), rush processing, and more. By the time all surcharges are added, the total cost per shipment can be two to three times the quoted per-entry fee.

When comparing brokers, always ask for an all-in quote that covers everything required to clear your typical shipment. This should include the customs entry filing, ISF filing, all applicable PGA submissions, duty calculation, bond management, and standard communication with CBP. If a broker cannot provide an all-in number, they are likely planning to make up the difference in surcharges.

4. Evaluate Technology

The technology a customs broker uses directly affects the speed, accuracy, and transparency of your import operations. Modern customs brokerage requires modern tools.

Look for a broker that offers:

• Self-service portal — a secure online platform where you can upload documents, track shipment status, view entry history, and download compliance reports. This replaces the email-and-phone-call back-and-forth that slows down less technologically capable brokers.
• Digital document submission — the ability to upload commercial invoices, packing lists, and other documents electronically rather than sending them by email attachment, fax, or (worst case) physical mail.
• Real-time shipment tracking — visibility into where your shipment is in the clearance process, from ISF filing through entry filing through CBP release.
• Classification database — a searchable record of your product classifications that ensures consistency across entries and simplifies re-orders of previously imported products.

Brokers who still rely primarily on email, phone calls, and fax machines are more likely to experience communication delays, filing errors, and document management issues. Technology is not a luxury — it is a baseline requirement for reliable customs brokerage in 2026.

5. Assess Response Time

When your shipment is being examined at the port, when a PGA places a hold, or when CBP issues a request for information, response time determines how quickly the issue gets resolved — and how much it costs you in storage charges, demurrage fees, and supply chain disruption.

Ask any broker you are considering:

• What is your typical response time for urgent issues?
• Do you guarantee a filing timeline? If so, what is it?
• Who is my primary point of contact, and what are their working hours?
• How do you handle issues that arise outside business hours?
• What is your process when a shipment is selected for examination?

6. Ask About Compliance Support

There is a meaningful difference between a customs broker who simply files entries and one who actively manages your compliance. Filing entries is the minimum — the real value of a customs broker is in preventing problems before they happen.

A compliance-focused broker provides:

• Classification reviews — periodic audits of your product classifications to ensure accuracy and identify duty savings opportunities.
• Regulatory monitoring — proactive alerts about changes to tariff rates, PGA requirements, trade agreements, and CBP policies that affect your products.
• Audit preparation — support in preparing for CBP Focused Assessment and Compliance Assessment audits, including record review, classification validation, and valuation analysis.
• Trade program enrollment — guidance on programs like C-TPAT (Customs-Trade Partnership Against Terrorism), duty drawback, Foreign Trade Zones, and trade preference agreements that can reduce your costs and streamline your clearance process.

Ask the broker: "Do you just file entries, or do you also help me optimize my classifications, prepare for audits, and stay ahead of regulatory changes?" The answer will tell you whether they are a transaction processor or a compliance partner. For a full comparison of broker types, see our guide on customs broker vs. freight forwarder.

7. Check References and Reviews

Ask the broker for references from current clients — specifically from importers in your product category. A broker who specializes in your industry should be able to provide multiple references without hesitation. When speaking with references, ask about accuracy of filings, response time for urgent issues, pricing transparency (were there unexpected surcharges?), the quality of their technology platform, and their willingness to provide compliance guidance beyond basic entry filing.

Also check online reviews, industry association memberships (NCBFAA, local customs broker associations), and any disciplinary history with CBP. A broker's reputation in the industry is one of the strongest indicators of the service you will receive.

Red Flags to Watch For

Knowing what to avoid is just as important as knowing what to look for. Here are the warning signs that a customs broker may not be the right fit.

No Clear Pricing

If a broker cannot give you a clear, all-in quote for clearing your typical shipment, their pricing model is designed to generate revenue from surcharges. This is the most common complaint importers have about their brokers — and the easiest problem to avoid by asking the right questions upfront.

Cannot Explain Your Product's HTS Code

If you ask a broker how they would classify your product and they cannot explain the reasoning behind the HTS code, they either have not done the work or do not understand it well enough to defend the classification in a CBP inquiry. Classification is the foundation of customs compliance — everything else (duty calculation, PGA requirements, special tariffs) flows from the HTS code. A broker who cannot explain their classification logic is a broker who is guessing.

No Portal Access

In 2026, a customs broker without a self-service portal is operating with outdated infrastructure. If you cannot upload documents online, track your shipments in real time, and access your entry history without calling or emailing your broker, you will spend unnecessary time on administrative tasks that should be automated.

Slow Response

If a broker takes more than a few hours to respond to your initial inquiry, consider how they will perform when your shipment is sitting at the port with an examination hold. Response time during the sales process is a reliable indicator of response time during active service.

No Compliance Beyond Entry Filing

A broker who only files entries and does nothing else — no classification reviews, no regulatory updates, no audit support, no proactive compliance monitoring — is providing commodity service at a time when trade compliance requires strategic thinking. The regulatory environment is too complex and too fast-moving for a file-and-forget approach.

How to Switch Customs Brokers

If your current broker is underperforming, switching is easier than most importers realize. There is no contractual lock-in with most brokers, and the transition process is straightforward.

Step 1: Choose Your New Broker

Evaluate potential brokers using the seven criteria above. Request an all-in quote based on your typical shipment volume, product types, and ports of entry. Ask for references from importers in your industry.

Step 2: Sign a Power of Attorney

You grant your new broker a power of attorney (POA) that authorizes them to act on your behalf before CBP. This is a standard form that takes minutes to complete. You can have active POAs with multiple brokers simultaneously, or you can revoke your previous broker's POA when you sign with the new one.

Step 3: Transfer Your Records

Your new broker can request your entry history and classification database from your previous broker. CBP regulations require brokers to maintain records for five years and to make them available upon request. This ensures continuity and allows your new broker to maintain consistent classifications across your entries.

Step 4: Begin Filing

Once the POA is signed and your records are transferred, your new broker handles all future entries. The transition can be completed within a few days for most importers. There is no gap in coverage and no disruption to your import operations.
