Ammonium sulfate contains two nutrition elements: nitrogen and sulfur. It is mainly used as a kind of nitrogen fertilizer. Meanwhile, it is also an important sulfur fertilizer applied widely in the world. As a kind of ammonium nitrogen fertilizer, ammonium sulfate can be absorbed by plants easily. It is an ideal top application fertilizer, seed fertilizer and base fertilizer. Ammonium sulfate is suitable for alkaline soil and sulfur-lacking soil.

China’s coke output was 183.28 million tons in the first half of 2012, up 6.44% from 172.20 million tons in January - May of last year. In addition, ammonium sulfate output from caprolactam production and the desulfurization of flue gas at electric power plants is increasing. China’s ammonium sulfate output in the first half of this year is estimated to have been about 2.0 million tons, a record high.

Demand for ammonium sulfate from NPK production was high. Although the demand for ammonium sulfate in rare-earth production was soft, the total demand for ammonium sulfate was increased.

China exports about 30% of its ammonium sulfate output annually without collecting export tax. China produced about 3.5m tons of ammonium sulfate in 2011, about 500kt more than last year. However, China exported 1.8m tons of ammonium sulfate in 2011, 601kt more than 2010. Driving by rising demand from international markets and domestic rare earth industry, ammonium sulfate prices increased sharply and its supply had been tight in 2011.

The ammonium sulfate industry is supported by many preferential policies such as no export tariff, rebate of value-added tax (50%), favorable railway transportation freight rate, and financial support for off season reserves. Prices of ammonium sulfate are estimated to grow slightly in the future.
