Companhia Siderúrgica Nacional (CSN), Brazil's second largest producer of flat steel products, Wednesday announced an increase of domestic prices by as much as 7.5 percent for the second quarter, in response to the recent doubling of iron ore costs in the international market.
Along with other major steel producers around the world, Sao Paulo-based CSN will adopt a quarterly pricing system as dictated by the three main iron ore producers, Vale, BHP Billiton and Rio Tinto.
