Sea freight services are essential for transporting goods over long distances, particularly for bulk shipments and heavy cargo. These services typically involve container shipping, where goods are loaded into large containers that can be easily transferred between ships, trucks, and trains. Major shipping lines like Maersk, MSC, and CMA CGM dominate the market, providing regular schedules on key trade routes.

Ports are crucial to sea freight logistics; major hubs include ports in Panama, Brazil, Chile, and Mexico, which facilitate trade across the Americas and beyond. Sea freight is generally more cost-effective than air freight, especially for non-urgent shipments, but it does take longer, often requiring several weeks for transit.
