The customs broker license examination is the federal test administered by U.S. Customs and Border Protection (CBP) that you must pass to become a licensed customs broker. It is offered once per year, covers tariff classification, entry procedures, valuation, and customs law, and has a historical pass rate between 10% and 20% — making it one of the most difficult professional licensing exams in the United States.
This guide walks you through every step: eligibility requirements, exam format, registration, study strategies, costs, and what happens after you pass.
What Is the Customs Broker License Examination?
Customs broker license examination: A federally mandated, open-book test administered by CBP under the authority of 19 USC § 1641 that evaluates a candidate’s knowledge of U.S. customs laws, regulations, tariff classification, trade procedures, and entry requirements. Passing the exam is the first major step toward obtaining a customs broker license.
CBP conducts the exam once per year, typically in October. Before 2023, it was offered twice annually (April and October), but CBP shifted to an annual format. The exam is proctored at designated testing centers across the country.
The purpose of the exam is straightforward: to ensure that anyone handling customs entries on behalf of importers has demonstrated competence in U.S. trade law. Customs brokers are the licensed professionals who file entry documentation, classify goods, calculate duties, and ensure compliance with CBP regulations. A single classification error can cost an importer thousands of dollars in penalties — or delay cargo for weeks.

Eligibility Requirements
Before you register, confirm you meet CBP’s eligibility criteria. The requirements are outlined in 19 CFR § 111.11:
- U.S. citizenship: You must be a citizen of the United States. Permanent residents and non-citizens are not eligible.
- Age: You must be at least 18 years old on the date of the exam.
- Moral character: CBP conducts a background investigation after you pass. Felony convictions or customs violations may disqualify you.
- No specific degree required: There is no formal education prerequisite. You do not need a college degree, though many candidates have backgrounds in international trade, supply chain management, or business.
There is no requirement for prior work experience in customs brokerage to sit for the exam. Anyone who meets the citizenship and age requirements can register.
What You Do Not Need
This is worth emphasizing because it surprises many candidates:
- No college degree
- No prior customs brokerage experience
- No sponsorship from a brokerage firm
- No pre-approval from CBP (beyond the application)
The exam itself is the gatekeeper. If you can pass it, you have met the knowledge requirement.
Exam Format and Content
The customs broker license examination is a timed, open-book test consisting of 80 multiple-choice questions. You have 4 hours and 30 minutes to complete it.
What the Exam Covers
The questions are drawn from these core subject areas:
| Subject Area | Approximate Weight | Key References |
|---|---|---|
| Tariff classification (HTS) | 25–30% | Harmonized Tariff Schedule |
| Entry procedures | 15–20% | 19 CFR Parts 141–149 |
| Valuation | 10–15% | 19 CFR Part 152, 19 USC § 1401a |
| Marking and country of origin | 5–10% | 19 CFR Part 134 |
| Bonding and penalties | 5–10% | 19 CFR Parts 113, 162, 171 |
| Trade agreements and special programs | 5–10% | USMCA, GSP, FTZs |
| Broker compliance and recordkeeping | 5–10% | 19 CFR Part 111 |
| Antidumping and countervailing duties | 5–8% | 19 CFR Part 159, AD/CVD orders |
| Miscellaneous (FDA, EPA, quotas) | 5–10% | Various agency requirements |
Reference Materials Allowed
Because the exam is open-book, you can bring physical copies of:
- The Harmonized Tariff Schedule of the United States (HTSUS)
- Title 19 of the Code of Federal Regulations (19 CFR)
- Title 19 of the United States Code (19 USC)
- Customs Directives and rulings (printed)
You cannot bring electronic devices, pre-tabbed personal notes pasted into your references, or commercially prepared study guides into the testing room. You can, however, tab and highlight your official reference materials — and this is strongly recommended.
Passing Score
You need a score of 75% or higher (at least 60 correct answers out of 80) to pass.
Pass Rates and Why the Exam Is So Difficult
The customs broker license examination has one of the lowest pass rates of any U.S. professional licensing exam. According to data from CBP and the National Customs Brokers & Forwarders Association of America (NCBFAA), pass rates typically fall between 10% and 20% in any given administration.
Some exam years have seen pass rates as low as 3.3% (October 2019), while others have reached the mid-20s. The average over the last decade sits around 13–17%.
Why is it so hard?
- Volume of material. The HTSUS alone is over 3,800 pages. Title 19 CFR spans hundreds of sections. Candidates must be able to locate answers quickly across thousands of pages.
- Tricky question design. Many questions test edge cases and exceptions, not general rules. Two answer choices often look correct, and the difference comes down to a specific regulatory nuance.
- Time pressure. At 80 questions in 270 minutes, you have roughly 3 minutes and 22 seconds per question. For classification questions requiring HTS lookup, that is tight.
- Open-book illusion. Candidates assume open-book means easy. In practice, if you don’t already know where to find the answer, flipping through 19 CFR under time pressure is a losing strategy.
The low pass rate is not meant to discourage you. It is meant to tell you this: serious, structured preparation is not optional. It is the single biggest factor separating those who pass from those who don’t.
How to Study for the Customs Broker Exam
Successful candidates generally dedicate 3–6 months of focused study before the exam. Here is a proven approach.
Step 1: Get Your Reference Materials Early
Order physical copies of:
- The Harmonized Tariff Schedule (print it or buy a bound copy)
- Title 19 CFR (available from the Government Publishing Office)
- Title 19 USC
Begin tabbing and annotating immediately. Your ability to navigate these materials under time pressure is arguably more important than memorizing content.
Step 2: Choose a Study Resource
| Resource Type | Cost Range | Best For |
|---|---|---|
| Self-study (free CBP materials + past exams) | $0–$100 | Disciplined self-learners with trade background |
| Online prep course (e.g., Boskage, CBET) | $500–$1,500 | Structured learners who need guidance and practice exams |
| In-person prep seminar | $1,000–$2,500 | Hands-on learners who benefit from classroom instruction |
| Study group / mentorship | $0–$500 | Candidates who need accountability and peer support |
CBP publishes past exam questions and answer keys on cbp.gov. These are your single most valuable study tool. Work through at least 5–10 prior exams under timed conditions.
Step 3: Master the HTS
Tariff classification questions make up the largest portion of the exam. You should be able to:
- Navigate the General Rules of Interpretation (GRI 1–6)
- Use Section and Chapter Notes
- Identify the correct heading and subheading for a described product
- Apply Additional U.S. Notes where relevant
Practice classification questions daily. Use the CBP Binding Rulings database to see how CBP classifies real products — this builds intuition.
Step 4: Practice Under Timed Conditions
Take full-length practice exams with the clock running. This is non-negotiable. Many candidates fail not because they lack knowledge, but because they run out of time. Learn to skip difficult questions, mark them, and return later.

What Happens After You Get Licensed
Once you hold your customs broker license, you can legally file customs entries and transact customs business on behalf of importers. You have several career paths:
- Join an established brokerage firm. Most newly licensed brokers start here, gaining experience handling entries across different commodities and ports.
- Work for a freight forwarder with a brokerage division. Many large logistics companies employ licensed brokers in-house.
- Open your own brokerage. With your individual license, you can apply for a district permit and begin serving clients directly.
- Specialize. Many brokers build expertise in specific industries — automotive imports, pharmaceutical compliance, food and beverage regulations, or electronics. You can browse by specialty (automotive, pharmaceutical, food, electronics, chemicals) to see how brokers position themselves by vertical.
Licensed customs brokers operate at every major port in the United States. Whether you want to work at a busy seaport, a land border crossing, or an airport cargo facility, you can browse by U.S. port of entry to see where brokers are concentrated. You can also browse brokers by state to understand the geographic distribution of licensed brokers across the country.

Frequently Asked Questions
What is the customs broker license examination?
The customs broker license examination is a federal test administered by U.S. Customs and Border Protection (CBP) that individuals must pass to become a licensed customs broker. It covers tariff classification, entry procedures, valuation, trade agreements, and customs law under Title 19 of the U.S. Code. The exam consists of 80 multiple-choice questions, is open-book, and requires a score of 75% or higher to pass.
How do I register for the customs broker license exam?
You register through CBP by submitting an application (CBP Form 3124E) during the open registration period, typically 2–3 months before the exam date. You must also pay the $200 examination fee at the time of registration. CBP publishes registration dates and testing center locations in the Federal Register and on cbp.gov.
How much does the customs broker license exam cost?
The examination fee is $200, payable to CBP at registration. After passing, you must pay an additional $300 permit fee to obtain your broker license. Study materials, prep courses, and reference books can add $300–$2,000 or more depending on the resources you choose, bringing the total investment to roughly $550–$2,800.
What is the difference between the customs broker exam and the customs broker license?
The exam is a single test you must pass to demonstrate knowledge of customs law and procedures. The license is issued by CBP after you pass the exam, complete a background check, and submit a separate license application (CBP Form 3124). Passing the exam alone does not make you a licensed broker — the background investigation and application process can take an additional 6–12 months.
What is the most common mistake people make when preparing for the customs broker exam?
The most common mistake is memorizing answers instead of learning how to navigate reference materials efficiently. The exam is open-book, so the key skill is locating correct answers quickly in the Harmonized Tariff Schedule, Title 19 CFR, and customs rulings. Candidates who treat it like a closed-book exam and try to memorize regulations consistently underperform compared to those who practice timed lookups.
