CBLE Mastery: Broker Exam Prep

CBLE Mastery is an independent study aid. It is not affiliated with, endorsed by, sponsored by, or acting for U.S. Customs and Border Protection or any other government agency. It does not provide government services and does not issue licenses or permits. Exam rules, procedures, and passing standards can change; always confirm current requirements with the official CBP sources listed below. Offline preparation for the U.S. Customs Broker License Examination. Eighty questions in 4½ hours, open book (HTSUS and 19 CFR), 75% to pass (60 of 80). WHAT YOU GET • 2,290 answerable questions: 1,650 for practice plus eight 80-question mocks timed to 270 minutes • All five released CBP papers — April 2026, October 2025, April 2025, October 2024, May 2024 • 1,075 notes on why wrong answers are wrong, covering 362 of 382 scored released questions • 340 sections of 19 CFR plus the HTSUS notes the answer keys cite, bundled and dated • A 19-module course: broker compliance, entry, classification, valuation, quota, drawback, bonds, ACE, marking and origin On released papers, each distractor is explained against regulation text that ships in the app. Where CBP's published key cites a section that does not exist, the published citation stays and the correction sits beside it. Two calculators: working-day deadlines under 19 CFR 101.6, and duty / MPF / HMF. Both work offline. The duty calculator is withheld during a timed mock. No account. Everything except ads is on the device. Nothing syncs; uninstalling erases progress. Readiness is an estimate from recency, blueprint coverage and timed papers — no study aid can promise a result. FREE, SUPPORTED BY ADS A banner while you browse or read, and an interstitial after a finished session. Never during a question. Every released paper and constructed mock form starts without watching an ad.
