Ocean freight is the most commonly used method of cargo transportation in global trade and is known as the lifeblood of global trade. It excels in transporting bulky cargo and may even be the only option for some cargo that cannot be transported by other means. Maritime transportation has the characteristics of large-scale transportation, wide application range, relatively slow speed, and environmental friendliness.

In the freight and logistics industry, the costs of different transportation methods vary based on a variety of factors, including distance, cargo type, transit time, and destination. However, across the board, the cheapest shipping methods are usually ocean freight and truck freight. Sea freight is a method of transporting goods by sea and is suitable for large-volume international trade. Trucking is a method of transporting goods over land and is suitable for domestic transportation over short to medium distances.

The three main types of freight are air freight, ocean freight, and trucking. Air freight is the fastest way to ship, sea freight takes longer, and trucking offers flexibility. Each method has its own characteristics and advantages, and plays different roles in different scenarios.
