Customs clearance is the process through which goods are authorized to enter or exit a country by passing through customs. It applies to shipments transported by sea, air, or land. Once customs clearance is completed, the shipper receives a document confirming that all customs duties have been paid and the goods can proceed. This process is typically handled by a freight forwarder, but a customs broker can also be hired. Customs clearance involves the payment of customs duties and adherence to local laws and regulations. It is a crucial step in the global movement of goods, ensuring compliance and facilitating the smooth flow of trade across borders.
