CBLE Prep: Customs Broker Exam
1,417 original practice questions, full timed simulations and an adaptive study plan for the U.S. Customs Broker License Examination (CBLE).
Built to prepare you for the CBLE
- 1,417 original practice questions across the six CBLE subject areas: Entry / Entry Summary, Classification, Valuation / Appraisement / Duty, Broker Compliance, Modernized Drawback and Practical Exercises.
- Full simulations in the exam's format: 80 questions, 4 hours 30 minutes, 75% to pass, with a complete review of every answer afterwards.
- A study plan that adapts to you: spaced repetition brings each question back just before you would forget it, and missed questions return until you answer them correctly twice.
- A readiness estimate and mastery by topic, so you can see where to focus next.
Every answer teaches
- Every question explains the correct answer and why each other option is wrong.
- Every question cites the rule behind it: 19 CFR (Parts 111, 141, 142, 152, 190 and more) and the HTSUS General Rules of Interpretation, so you practice finding the right provision, which is what the exam tests.
- Every question has an exam tip, a common trap and a learning objective.
Checked against the exam's reference editions
The question bank was audited question by question against the editions listed for the October 2026 exam: 19 CFR (2025 Annual Edition), HTSUS 2026, ACE Entry Summary Instructions v2.4a and CBP Directive 3530-002A. Where current practice differs from those editions, the explanation says so, and every question has a "Report a problem" button so that errors get fixed.

What it is, and what it is not
CBLE Prep is an independent study aid by an independent developer. Its questions are original practice questions, not actual exam questions, and the app is not affiliated with or endorsed by U.S. Customs and Border Protection. Use it together with the official reference materials; no study aid can guarantee an exam result.
