Bulk transport involves shipping goods or cargo with large trucks, trains or maritime vessels. Usually, these types of items are not packaged in boxes and are raw goods and materials. Common examples of bulk items transported this way include coal, grain and petroleum.
Bulk shipping fees are called freight. As of September 2014, nearly half of the world's maritime shipping is involved in bulk transport. Freight transport is closely linked economic prosperity and growth. When a consumer-based economy grows, manufacturers and producers must ship bulk freight elsewhere to make money. One factor that influences bulk transport is the final profit margin after consumer purchases - for instance, electrical equipment is worth more than wood products per ton of freight.
