From East Asia Forum:
In 2008, to compete with BHP and Rio Tinto over shipping costs, the shipping company Vale commissioned, at a cost of over US$2 billion, a new line of ‘Very Large Ore Carriers’ (VLOCs), dubbed the ‘Valemax’. The Valemax carrier is the largest bulk carrier ever built: over twice as big as Cape-size carriers (400,000 dwt). Current shipping costs from Australia to China stand at around US$10/tonne, whereas it currently costs around US$22/tonne to ship iron ore from Brazil to China. Direct Valemax trips from Brazil to China would bring shipping costs down to aboutUS$15/tonne.
