You should also consider hiring a “Customs Broker” --- that is, a private individual or company licensed, regulated and empowered by U.S. Customs and Border Protection (CBP) to assist importers and exporters in meeting the federal law requirements. Brokers must have expertise in the entry procedures, admissibility requirements, classification, valuation, and the rates of duty and applicable taxes and fees for imported merchandise. Brokers may submit information and payments to CBP on behalf of their clients and charge them a fee for this service. There are approximately 11,000 licensed Customs Brokers in the United States.
