CBLE Past Exams and Answer Keys: What the Last Four Papers Test

U.S. Customs and Border Protection (CBP) posts recent Customs Broker License Exams (CBLE) on its website, each with an answer key. So the real papers are available to download. For almost every question, the four keys we reviewed (October 2024 to April 2026) give the answer and the reference behind it, but they do not explain why the options CBP did not accept are wrong: they say which section, not why. This guide looks at the four most recent papers on CBP's page (October 2024, April 2025, October 2025 and April 2026), shows how each is built, counts which parts of 19 CFR the keys cite most, and walks through one real question. ProSyllabus is an independent study site, not part of U.S. Customs and Border Protection.

CBP General CBLE Information and the April 2026 exam cover page; CBP past exams page, read 21 Oct 2026.

CBP's "Past Customs Broker License Examinations & Answer Keys" page lists the exams and keys for May 2024, October 2024, April 2025, October 2025 and April 2026. Each is a separate PDF. The page carries one warning worth reading before you mark yourself: "Answer keys are not modified post-appeal decisions". In other words, if CBP later gave credit for a different option on appeal, the key you download will not show it.

The published keys also identify questions for which every examinee was given credit and questions with two accepted answers. On the October 2025 key, questions 13 and 73 read "All examinees granted credit", and questions 56 and 78 list two accepted answers (B and D). On the April 2026 key, question 73 reads "All examinees granted credit" and question 61 lists two accepted answers (B and D). When you score a past paper, count an all-credit question as correct whatever you chose, and on a double-keyed question accept either listed answer.

Can a study site reproduce these papers? CBP's copyright notice says that, unless a copyright is indicated, information on its website "is in the public domain and may be reproduced, published or otherwise used without the permission of the CBP", and asks that CBP be cited. The non-disclosure agreement examinees sign covers the exam only until all exams have been completed, "after 12 midnight on exam day". So the questions quoted on this page are CBP's, cited to CBP; the explanations are ours.

Each of the four papers from October 2024 to April 2026 opens with a table of six categories and the question numbers in each. The order is the same on all four: Broker Compliance first, Valuation last. The middle shifts. Modernized Drawback had its own five questions in October 2024 and April 2025; from October 2025 that slot became Quota. Classification fell from 15 questions to 10, and Broker Compliance rose from 15 to 20, then fell to 17.

Question counts from each paper's own category table (CBP publications for October 2024, April 2025, October 2025 and April 2026). Each row adds up to 80.

Two things follow. First, Entry / Entry Summary has been 25 questions, questions 41 to 65, on all four papers: nearly a third of the exam sits in one category. Second, the categories are a map, not a syllabus. CBP's general page lists the typical categories (entry, partner government agencies, foreign trade zones and bonded warehouses, bonds, intellectual property rights, marking and country of origin, drawback, classification, valuation, antidumping and countervailing duty, trade agreements, broker compliance, powers of attorney, recordkeeping, fines and penalties, continuing education, quota, practical exercises) and ends with "Other subjects that are relevant to a broker's duties".

Almost every key line names the provision behind the answer (the all-credit questions carry no citation). We read all 320 question entries in the four keys from October 2024 to April 2026 and counted how many questions cite each Part of Title 19 at least once. A question can cite several Parts, so the rows overlap.

Our count of CBP's answer-key citations for October 2024, April 2025, October 2025 and April 2026. Not a CBP figure. Part names are the Part headings in the eCFR (19 CFR as revised January 1, 2024). Citations are counted as printed: April 2026 question 74 is printed "19 CFR 151.102-103" and is not counted under Part 152.

Part 111, the broker regulations themselves (headed "Customs Brokers"), leads by a distance. Part 141, "Entry of Merchandise", is next; its Subpart C, "Powers of Attorney", is short (sections 141.31 to 141.46) and worth knowing well. Part 152 holds the valuation rules, in its Subpart E, "Valuation of Merchandise". The HTSUS is the other big reference: classification questions cite General Rules of Interpretation, section and chapter notes, and eight- or ten-digit subheadings.

Editions matter when you work an old paper. Each paper's cover page names its own editions, and a past answer can rest on text that has since changed. Check the edition on the cover before you argue with a key.

From each paper's cover page, and for October 2026 from CBP's Registration Information page.

Here is the first question of the April 2026 paper, quoted from CBP's published exam. Try it before you open the answer. Then read the explanation the way you would want to read every one: the rule, where it is, and why each wrong option is wrong.

A past paper is worth most the first time you sit it, so do not spend it on reading. This is our suggested routine, not CBP guidance.

Do the papers in date order and leave the newest for last, closest to your sitting. Our suggestion is to save the newest paper for last; CBP says its practices now include developing questions with industrial-organizational psychologists and conducting pre-exam legal reviews.

For most questions the key gives one letter and one or more citations. It does not say why each other option is wrong. When reviewing an option, we suggest checking its deadline, the responsible party and the required form. In our view, a walked-through answer can help you understand the cited rule and apply it when it comes up again in different words.

It also cannot tell you what changed on appeal. CBP's note that keys are not modified after appeal decisions means a published key is CBP's answer at the time of publication, nothing more. If your reasoning from the cited section points elsewhere, check the edition on the cover first; the regulation may have been amended since.
