A Customs Broker must inform whom about any changes in circumstances?

The correct answer is that a Customs Broker must inform his or her client about any changes in circumstances. This obligation is rooted in the fiduciary duty that a Customs Broker has towards their client. A Customs Broker is responsible for acting in the best interest of their client, which includes keeping them informed of any developments that could affect their business or shipping processes.

For instance, if there are changes in tariffs, regulations, or specific details regarding a shipment, the Customs Broker must communicate these to the client so they can make informed decisions. This communication helps maintain a transparent and trustworthy relationship, ensuring that both parties are aligned and can respond appropriately to any new information.

While there are requirements to communicate with entities like the Bureau of Customs or port authorities in certain contexts, those obligations pertain to compliance with regulations rather than the direct client relationship. Therefore, the primary focus is on maintaining communication with the client as a standard practice for effective brokerage services.
