Oil, iron ore, grain and coal accounted for the great majority of ton-miles shipped, about 70% in
2005. Containers and other goods composed the remaining 30%. While the share of containerized
traffic has increased significantly, bulk still dominates maritime shipping. It may be argued that
raw materials play only a small part in influencing industrial location in general. Nevertheless,
there are a number of basic heavy industries - mineral and chemical refining most obviously -
where the volume of bulk materials does have a profound impact on the location of processing
industries and also on shipping markets, patterns of trade and port activity.
