Ocean freight is the transportation of goods by sea, typically used for large, heavy, or high-volume shipments moving internationally. It is the most cost-effective way to move significant quantities of goods across long distances, though transit times are longer than air. For manufacturers and distributors importing raw materials or finished goods, or exporting products to international markets, ocean freight is usually a core part of the supply chain. Managing it well, with the right carrier relationships, documentation, and visibility, makes a meaningful difference to both cost and operational reliability.
