In transacting customs business, licensed customs brokers must exercise responsible supervision and control. CBP's determination of what is necessary to perform and maintain responsible supervision and control will vary depending upon the circumstances in each instance. Regardless of the circumstances, which ONE of the following factors is a mandatory requirement for licensed customs brokers to exercise responsible supervision and control when conducting customs business?
What happened
CBP's answer key for this question reads "All examinees granted credit." Every choice was scored correct.
Why the question was flawed
The question asks for the one mandatory requirement "regardless of the circumstances." Training (B), access to regulations (C) and audits (A) are listed as discretionary factors CBP may consider. The "sufficient number of licensed brokers" requirement (D) is phrased as a must, but what counts as "sufficient" depends on the circumstances, which conflicts with the question's "regardless of the circumstances" wording. That ambiguity is the likely reason CBP voided it.
