US Customs Broker License Exam (CBLE)

Find the answer before the clock runs out

The customs broker exam is open book. You get 80 multiple-choice questions in 4.5 hours and need 75% (60 right) to pass. Most people who fail run out of time looking things up, so this site drills the lookup.

The short version: the next exam is expected in April 2027. CBP posts the reference list about 10 weeks before, when registration opens. Until then, the best bet is the HTSUS 2026 Basic Edition and 19 CFR, revised as of April 1, 2025, which is what this site uses.
