The customs broker exam is a standardized test administered by U.S. Customs and Border Protection (CBP) that you must pass to become a licensed customs broker in the United States. The exam covers tariff classification, customs law, entry procedures, valuation, and trade compliance — and historically, fewer than 20% of test-takers pass on their first attempt.
This guide breaks down everything you need to know: eligibility requirements, exam format, costs, study strategies, and what happens after you pass. Whether you are planning your first attempt or recovering from a failed one, this is the most complete resource available.
Customs broker exam: A 4.5-hour, open-book examination consisting of 80 multiple-choice questions administered by CBP under 19 CFR Part 111. Candidates must score 75% (60 correct answers) or higher to pass. The exam tests practical knowledge of customs regulations, the Harmonized Tariff Schedule (HTS), trade agreements, and import/export procedures required to transact customs business on behalf of importers.
Who Is Eligible to Take the Customs Broker Exam?
CBP sets clear eligibility requirements under 19 CFR § 111.11. You must meet all of the following criteria before you can register:
- U.S. citizenship — You must be a citizen of the United States. Permanent residents and visa holders are not eligible.
- Age requirement — You must be at least 21 years old on the date of the exam.
- No federal employment — You cannot be a current employee of the U.S. federal government at the time of the exam.
- No felony convictions — Certain criminal convictions can disqualify you, though CBP evaluates these on a case-by-case basis.
There is no educational requirement. You do not need a college degree, a specific major, or prior work experience in customs brokerage. Anyone who meets the basic eligibility criteria can sit for the exam.
Common Eligibility Misconceptions
Many candidates assume they need years of industry experience or a degree in international trade. That is not the case. CBP’s licensing process separates the exam from the license application. You can pass the exam with zero professional experience. However, practical experience makes the material significantly easier to understand, which is why many test-takers work in logistics, freight forwarding, or trade compliance before attempting the exam.

Customs Broker Exam Format and Structure
The exam is offered twice per year — typically in April and October — at designated testing centers across the country. Here is what to expect:
| Exam Detail | Specification |
|---|---|
| Duration | 4 hours, 30 minutes |
| Number of questions | 80 multiple-choice |
| Passing score | 75% (60 out of 80 correct) |
| Format | Open-book (physical reference materials allowed) |
| Frequency | Twice per year (April and October) |
| Testing fee | $200 per attempt |
| Administered by | U.S. Customs and Border Protection (CBP) |
| Governing regulation | 19 CFR Part 111 |
What Reference Materials Can You Bring?
The customs broker exam is open-book, which means you can bring physical copies of approved reference materials into the testing room. Allowed materials typically include:
- Harmonized Tariff Schedule of the United States (HTSUS) — available at hts.usitc.gov
- Title 19, Code of Federal Regulations (19 CFR) — the full body of customs regulations
- Title 19, United States Code (19 USC) — the underlying customs statutes
- Customs Rulings — searchable at rulings.cbp.gov
- CBP Directives and informed compliance publications
Electronic devices, laptops, tablets, and phones are prohibited. You must bring printed, bound copies. Many candidates use tabbed, annotated reference books specifically designed for exam navigation. The ability to find answers quickly in these references is often the difference between passing and failing.
What Topics Does the Exam Cover?
The exam draws from several core subject areas:
- Tariff classification — Applying the correct HTS codes to goods using the General Rules of Interpretation (GRI)
- Customs valuation — Determining the transaction value of imported merchandise under 19 USC § 1401a
- Entry procedures — Filing entry summaries, immediate delivery entries, warehouse entries, and temporary importations (under bond)
- Marking and country of origin — Rules of origin under 19 CFR Part 134
- Trade agreements and preference programs — USMCA, GSP, and other preferential duty programs
- Penalties and enforcement — Liquidated damages, prior disclosures, and penalty mitigation under 19 USC § 1592
- Bonding — Customs bonds, types of bonds, and bond sufficiency requirements
- Antidumping and countervailing duties — Orders searchable at enforcement.trade.gov/adcvd
- Broker responsibilities — Duties of a licensed broker under 19 CFR Part 111
Tariff classification questions typically make up the largest share of the exam — often 25-30% of all questions. If you cannot efficiently navigate the HTSUS, passing becomes extremely difficult.
Customs Broker Exam Pass Rates and Difficulty
The customs broker exam has a well-earned reputation as one of the most difficult professional licensing exams in the United States. Here are the numbers:
- Historical pass rate: The overall pass rate has fluctuated between 11% and 27% over the past decade, with most recent exams landing between 15-20%.
- October 2023 pass rate: Approximately 17.6% of candidates passed.
- First-time pass rate: Even lower than the overall average — many candidates need 2-3 attempts before passing.
For context, the CPA exam has a pass rate of roughly 45-55% per section, and the bar exam averages around 58% nationally. The customs broker exam is harder to pass by the numbers.
Why Is the Pass Rate So Low?
Three factors drive the low pass rate:
-
The open-book format is deceptive. Candidates assume they can “just look things up” and underprepare. In reality, 80 questions in 4.5 hours means you have roughly 3 minutes and 22 seconds per question. If you do not already know where to find the answer, you will run out of time.
-
Tariff classification requires practiced skill. Classifying goods under the HTS is not straightforward memorization. It requires understanding the General Rules of Interpretation, Section and Chapter Notes, and how to navigate the tariff schedule efficiently.
-
The breadth of material is enormous. Title 19 CFR alone spans thousands of pages. The exam can pull questions from any section, making it impossible to memorize everything.
How to Study for the Customs Broker Exam
The most effective study strategy combines structured coursework with aggressive practice testing. Here is a breakdown of the main preparation approaches and their typical costs:
| Study Method | Cost Range | Best For |
|---|---|---|
| Self-study (books + free resources) | $100–$500 | Experienced trade professionals |
| Online prep course | $500–$1,500 | Most candidates; structured curriculum |
| Intensive boot camp | $1,500–$3,500 | Career changers, first-time takers who want structured accountability |
| Study group (informal) | Free–$200 | Supplement to other methods |
Recommended Study Timeline
Most successful candidates study for 3 to 6 months before the exam, dedicating 10-20 hours per week. Here is a sample timeline for a 4-month study plan:
- Month 1: Learn the structure of the HTSUS, 19 CFR, and 19 USC. Practice tabbing and indexing your reference materials. Focus on classification basics and the General Rules of Interpretation.
- Month 2: Study entry procedures, valuation, marking rules, and bonding. Begin timed practice questions — aim for 20-30 questions per study session.
- Month 3: Cover trade agreements, penalties, antidumping/countervailing duties, and broker responsibilities. Increase practice to full-length timed practice exams.
- Month 4: Full practice exams under real testing conditions (80 questions, 4.5 hours, open-book with your actual reference materials). Review every wrong answer and identify weak areas.
The Single Most Important Study Habit
Practice with your physical reference materials from day one. The exam is open-book, but speed is everything. The candidates who pass are the ones who can flip to the right page of the HTSUS or 19 CFR within 30 seconds. Tab your books extensively. Create a personal index. Practice until navigating your references feels automatic.

What Happens After You Pass the Exam
Passing the customs broker exam is a major milestone, but it does not immediately make you a licensed customs broker. Here is the post-exam process:
- Receive your score. CBP typically releases results 10-12 weeks after the exam date.
- Submit a license application. File CBP Form 3124 (Application for Customs Broker License) along with a $200 application fee. This is separate from the $200 exam fee.
- Background investigation. CBP conducts a thorough background check, including criminal history, credit, and character references. This process can take 6 to 12 months.
- Receive your license. If approved, CBP issues your individual broker license. You may also apply for a district permit to conduct business in a specific customs district, or a national permit to operate nationwide.
- Obtain a customs broker bond. Before you can transact customs business, you need a broker bond (minimum $50,000).
The total timeline from exam day to active licensed broker is typically 8 to 18 months, depending on how quickly you submit your application and how long the background check takes.

How the Customs Broker Exam Differs from Other Trade Credentials
Many professionals in international trade hold multiple certifications. Here is how the customs broker exam compares to other common credentials:
| Credential | Administered By | Format | Pass Rate | Result |
|---|---|---|---|---|
| Customs Broker Exam | CBP | 80 questions, open-book, 4.5 hours | ~15-20% | Federal license to transact customs business |
| Certified Customs Specialist (CCS) | NCBFAA | Multiple-choice, open-book | ~50-60% | Professional certification (not a license) |
| Licensed Customs Broker (Canada) | CBSA | Multiple exams over 2+ years | Varies | Canadian broker license |
| Certified Export Specialist (CES) | NCBFAA | Multiple-choice, open-book | ~55-65% | Professional certification for export compliance |
The critical distinction is that the customs broker exam leads to a federal license — not just a professional certification. Under 19 USC § 1641, only licensed customs brokers (or the importers themselves) may transact customs business with CBP. This legal monopoly is what makes the license valuable and the exam worth the effort.

Frequently Asked Questions
What is the customs broker exam?
The customs broker exam is a standardized test administered by U.S. Customs and Border Protection (CBP) that candidates must pass to obtain a customs broker license. It covers tariff classification, entry procedures, valuation, trade agreements, and customs law under Title 19 of the U.S. Code and Code of Federal Regulations. The exam consists of 80 multiple-choice questions, lasts 4.5 hours, and requires a score of 75% or higher to pass.
How do I register for the customs broker exam?
You register through CBP by submitting an application during the open registration period, typically 2-3 months before the exam date. You must be a U.S. citizen, at least 21 years old, and not a current federal employee. The application is submitted online through CBP’s designated portal along with the $200 exam fee. Check CBP.gov for the exact registration window and upcoming exam dates.
How much does it cost to take the customs broker exam?
The CBP exam fee is $200 per attempt. Total preparation costs range from $500 to $3,500+ depending on whether you self-study or enroll in a prep course. After passing, the license application fee is an additional $200, bringing the minimum total cost to approximately $400 for the exam and license alone. Most candidates spend $700-$2,000 total when including study materials and courses.
What is the difference between the customs broker exam and the customs broker license?
The customs broker exam is the standardized test you must pass. The customs broker license is the credential CBP issues after you pass the exam, submit a separate license application, clear a background check, and pay the $200 license fee. Passing the exam alone does not make you a licensed customs broker — the license application is a separate process that can take 6-12 months after your passing score is confirmed.
What is the most common mistake people make when preparing for the customs broker exam?
The most common mistake is memorizing regulations instead of practicing how to look them up quickly. The exam is open-book, and the key skill is efficient navigation of the Harmonized Tariff Schedule, Title 19 CFR, and customs rulings. Candidates who spend 80% of their study time on timed practice questions with reference materials consistently outperform those who try to memorize content. Start using your physical books from day one of studying.
