A customs broker is a federally licensed professional who files entries with US Customs and Border Protection (or its Canadian equivalent, CBSA) on behalf of an importer. They classify goods to the right HS code, calculate duty owed, file the entry electronically, advance the duty payment, and handle exceptions like document holds and FDA reviews. Major brokerages in North American ecommerce include Livingston International, A.N. Deringer, Cole International, FedEx Trade Networks, and C.H. Robinson Customs Brokerage.
How it works in practice
US Customs requires a licensed broker for any commercial entry valued at $2,500 or more. Below that, importers can theoretically self-file, but in practice almost every commercial importer uses a broker for every entry. The broker sits between the freight forwarder, the importer, and CBP. When a container arrives at the port of Los Angeles, the forwarder transmits the manifest, the broker files the entry summary with HS codes and declared values, the broker pays duty on the importer’s behalf via the broker’s bond, and the goods are released for delivery. The broker invoices the importer for duty plus a brokerage fee, typically $50-$250 per entry.
Why it matters
A good customs broker saves money on classification, prevents CBP penalties for misclassification, and gets goods released quickly. A bad broker bills the wrong HS code, overpays duty, or sits on exceptions until the freight accrues demurrage. The broker is also the entity on the hook when CBP audits an importer’s three-year duty history, so the relationship matters more than the per-entry fee.
Common misconceptions
- A customs broker is not a freight forwarder. Forwarders move freight, brokers clear customs. Many companies do both.
- The importer of record, not the broker, is legally responsible for the entry’s accuracy. The broker is the agent, the importer carries the liability.
- Brokers do not negotiate duty rates. They classify and pay what the HTS schedule says.
