Many of the world’s most traded goods require specialized maritime transport conveyances. Cars are the most traded goods in terms of value, implying the deployment of a car carrier fleet. The second most traded commodity is refined petroleum, which is carried in tankers. A wide range of commodities, such as vehicle parts, are carried in containers. High-value goods, including integrated circuits, computers, and pharmaceuticals, are more likely to be carried as air cargo.
