Sea freight refers to the transportation of goods by ships over oceans and seas. It is a common method for moving large quantities of cargo, including raw materials and finished products, between countries. This mode of transport is often more cost-effective than air freight, especially for heavy or bulky items. Shipping companies use various types of vessels, such as container ships and bulk carriers, to handle different types of cargo. Sea freight typically involves several steps, including loading goods at a port, transporting them across the water, and unloading them at the destination port for further distribution.
