Ocean freight is the most common mode of transport that importers and exporters use. In fact, a full 90% of everything is shipped by ocean freight and sea freight. The other international freight transport modes (courier, standard air freight, express air freight) are all faster, but they are also more expensive. Smaller shipments, and products with a high value, generally go by these other modes.
If ocean freight is too slow, but air freight is too pricey, some freight forwarders are now offering a relatively new service, often called expedited freight. This service is often nearly as quick as air freight, but it costs more like ocean freight. It works by streamlining ocean freight processes and only tying in with the faster ocean services and premium trucking services.
