On the whole, the unit weight of metal materials in 2010 decreased from last year, from US$1,568/ton to US$1,467/ton, a decrease of 6.4%. In terms of changes in product categories, the growth of non-ferrous metals manganese, copper, steel, and wire rods was significant, with year-on-year increases of 183.1%, 63.8%, 73.6%, and 84.5%, respectively; special-shaped steels, other steel products, and aluminum suffered large declines. The year-on-year decline was 92.7%, 67.3%, and 33.1%.
According to industry insiders, this is mainly due to the price fluctuations in the international and domestic metals markets and the increase in demand for catalyst materials such as manganese. Affected by the adjustment of Australian iron ore prices at the beginning of the year, many speculators in China have accumulated a large amount of raw materials, resulting in material purchase and export prices rising in the short term. In the following months, the domestic market did not exhibit the expected purchasing power, and spot steel products are thus large. The rate of decline and eager to get rid of, raw material price fluctuations have led to constant changes in costs. At the same time, due to China's elimination of part of the tax rebate on exports of primary processed metal materials on July 15th, the export of steel metal materials in the first and second half of the year was not balanced, and exports of primary products fell sharply in the second half of the year. In addition, with the recovery of the international market driving the demand for basic materials, the rapid growth in the demand for catalytic materials represented by manganese and the increase in export of copper materials driven by the recovery of the electronics industry have promoted a significant increase in the export amount of non-ferrous metals in Kunshan this year.
