Do I need a customs broker?

Not always — importers can file their own declarations. Most use a broker because classification, valuation and filing rules are detailed, and in the US anyone filing for others must hold a broker's licence.

Who is responsible if the customs broker makes a mistake?

In the US the importer of record keeps the duty to use reasonable care, so it owes the correct duty. In the EU, under direct representation the trader is liable; under indirect representation the representative and trader are jointly and severally liable.

How do you become a licensed customs broker in the US?

Be a US citizen aged 18 or over, pass the CBP broker exam — held in April and October — with 75% or more, and apply for the licence within 3 years of passing.

Term

Customs broker

A customs broker is a licensed agent who prepares and files customs declarations, classifies goods and pays duties on an importer's behalf. In the US, doing customs business for others needs a broker's licence from US Customs and Border Protection; in the EU the role is a customs representative, acting directly or indirectly for the trader.

Also called customs agent, customs house broker, customs representative, licensed customs brokerUpdated 12 October 2026

United States

No one may conduct customs business for others without a customs broker's licence; an individual licence goes only to US citizens.
The licensing exam is held on the fourth Wednesday of April and October, for candidates 18 or older; a pass needs 75% or more, within the 3 years before applying.
The importer of record must still make entry using reasonable care — in person or through an agent — so a broker's error does not move that duty off the importer.

In Dubai, a customs broker needs a no-objection certificate from Dubai Customs for a trade licence with brokerage activity — AED 700 for a new one, in its 2025 service guide.

Worked example: whose duty is it

Suppose a US importer brings in goods valued at USD 40,000, dutiable at 3.5%, and its broker declares them under a duty-free code by mistake.

Duty owed = 3.5% × 40,000 = USD 1,400 — still the importer's, because the reasonable-care duty sits with the importer of record

The importer may have a claim against the broker under their contract, but customs collects from the importer.

The mistake people make

Handing classification to the broker and not checking it. The broker files what the importer tells it, or what it can infer; product data, the HS code and the valuation are the importer's to own.
