There is no legal requirement to use a customs broker to clear your goods; however, many importers opt to do so for convenience. Customs Brokers are licensed by U.S. Customs & Border Protection to conduct Customs business on behalf of importers. The importer is ultimately responsible for knowing CBP requirements and for ensuring their importations comply with all federal regulations, but if you use a trained professional to clear your goods, it could save you from making costly mistakes.
