Ocean freight companies arrange the shipping of goods via sea in cargo ships. They handle container shipping for large volumes of goods, which is typically the most cost-effective way to move freight internationally (albeit slower than air). Ocean freight forwarders manage booking container space on vessels, preparing bills of lading, and ensuring all international shipping regulations are followed. They may also coordinate ground transport on either end (pre-carriage and on-carriage). For businesses involved in global trade, a reliable ocean freight service is essential to move inventory across continents while managing costs and customs clearance.
