What is a customs broker in supply chain?

A customs broker is a licensed professional or company that facilitates the clearance of goods through customs for importers and exporters. In the United States, customs brokers are licensed by U.S. Customs and Border Protection (CBP). Their primary role is to ensure shipments comply with all applicable laws and regulations while helping businesses calculate duties, prepare documentation, and avoid costly delays at the border.

In the supply chain, customs brokers act as intermediaries between shippers and government authorities, making global trade smoother, faster, and more compliant.

How a customs broker works in the supply chain

• Documentation management: Brokers prepare and submit essential customs forms, commercial invoices, packing lists, and certificates of origin.
• Duty and tax calculation: They classify goods under the correct Harmonized Tariff Schedule (HTS) codes and calculate tariffs, duties, and taxes.
• Regulatory compliance: Customs brokers ensure shipments meet requirements set by CBP and other government agencies (such as FDA, USDA, or EPA).
• Customs clearance: They coordinate with carriers, ports, and customs officials to expedite release of shipments.
• Advisory role: Many brokers advise businesses on compliance strategy, duty savings programs, and trade agreements (like USMCA).
