Definition & Explanation

Getting goods across a border lawfully starts with the customs declaration: a formal statement submitted to the customs authority containing all information required for assessment – commodity description, tariff classification, customs value, quantity, weight, and country of origin. The declaration is mandatory for imports, exports, and transit movements, and provides the legal basis for calculating duties, import taxes, and the application of trade measures. In practice, a customs broker or freight forwarder typically files the declaration on behalf of the importer or exporter, but the declarant remains legally responsible for its accuracy. Errors or omissions can result in fines, delays, seizure of goods, or criminal liability.
