A customs broker is a specialist authorised to prepare and submit customs declarations on behalf of importers and exporters. In some countries, customs brokers must also hold a government licence. A broker classifies goods, calculates duties and taxes, and makes sure documentation meets local customs requirements. Why it matters for your supply chain: Accurate declarations help avoid delays, penalties and overpaid duty at the border. This matters most when trade rules and tariffs are changing.
