Customs Broker

A licensed intermediary that files customs entries on behalf of an importer and advises on classification, valuation and admissibility.

The role

A customs broker is licensed to transact customs business on behalf of others. In the United States, licensing is administered by CBP under 19 CFR Part 111, and a broker must pass an examination, meet character and financial requirements, and hold a permit for each port or operate under a national permit.

In the EU the equivalent function is performed by customs agents and representatives, who may be direct representatives acting in the name of the importer or indirect representatives acting in their own name. The distinction matters, because an indirect representative can become jointly liable for the duty.

What the broker does

Classifies goods and applies the correct duty rate
Prepares and files the entry, including the entry summary
Arranges duty payment and, where required, a bond
Handles admissibility questions with other agencies, such as product safety or forced labour screening
Supports post-entry audits and corrections

The broker does not own the compliance decision. The importer of record remains responsible for the accuracy of the declaration, which is why a broker relationship is a professional service rather than a transfer of liability.

Choosing one

The useful questions are operational rather than commercial. Does the broker handle the product categories you import, including any partner government agency requirements? Can it support the entry types you need, and does it provide classification rationale in writing? What is the process for a detention, and who communicates with the agency?

Price per entry matters less than the cost of a misclassification discovered in an audit.

Where sellers get it wrong

Handing over a commercial invoice and expecting the broker to resolve everything. The importer is the source of truth for product description, material composition, origin and value. A broker filing on the basis of thin data is filing on the basis of the seller's assumptions.

The second error is treating the broker as a substitute for compliance evidence. A broker files the entry; it does not produce a Children's Product Certificate or resolve a UFLPA detention.

Relationship to other mechanisms

The broker is the practical interface for Entry Type 86 filings while that route existed, for current entries with Section 301 duty, for low-value shipments now dutiable after the end of de minimis, and for goods moving into a bonded warehouse.

FAQ

Is a customs broker legally required?

Not always. An importer can file its own entries, but the licensing, bonding and system access requirements make a broker the practical route for most commercial importers.

Who is liable for a wrong classification?

The importer of record carries the liability for the declaration. A broker may share responsibility in cases of its own negligence, but the duty and penalties attach primarily to the importer.

What does a broker need from the seller?

Accurate product descriptions, material composition, country of origin, value, quantities, and any certificates required by the product rules in force.

Does a broker handle detentions?

Most do, by filing responses and coordinating documents with the agency. The substantive evidence, such as supply chain tracing, still has to come from the importer.

How is the EU representative different?

A direct representative acts in the importer's name, while an indirect representative acts in its own name and can become jointly liable for the customs debt.
