A customs broker is a licensed professional or firm that helps importers and exporters clear goods through customs by preparing and submitting entry information, coordinating required documentation, and communicating with government agencies. In the United States, a customs broker works within the rules of U.S. Customs and Border Protection, but the broker does not make the law or guarantee that a shipment will be admitted without issue.
What a Customs Broker Handles
For a shipment arriving by ocean, air, or land, the broker may review commercial invoices, packing lists, bills of lading or air waybills, and other data needed to classify the goods, determine the proper duty treatment, and file the customs entry. Depending on the shipment, the broker may also help with admissibility concerns, partner government agency requirements, and corrections if information changes after arrival.
Businesses often use a customs broker when they do not have in-house customs expertise, when shipments are time-sensitive, or when products are subject to specialized rules. The broker's role is advisory and administrative: it is distinct from the freight forwarder arranging transport and from the carrier moving the cargo. Fees, authority, and responsibilities vary by contract and by jurisdiction, and the importer remains responsible for the accuracy of the information provided. For example, a U.S. importer bringing in manufactured parts may ask a broker to file the entry and flag any documentation gaps before the cargo is released.
