China is the largest producer and exporter of sodium sulfite. Jiangsu Province is the world's largest sodium sulfite production base and is expected to produce over 4.8 million metric tons by 2013. In 2003, We factory began commercial production of the world's largest sodium sulphite plant in nan jing. China's production, consumption, and exports of sodium sulfite have been increasing significantly in the past few years. In 2008, China represented more than three-fourths of the global capacity and more than 70% of the production.
In North America, the closure of several plants has helped to eliminate the oversupply situation the sodium sulfite market had faced in the past. Temporary suspensions of operations are also occurring as a reaction to the current global economic downturn. In early 2009, Exide at Baton Rouge announced temporary suspension of operations and Elementis at Castle Hayne declared force majeure because of the shrinking economy. North American demand has been decreasing in both the textile industry because of the entry of cheaper imports and in the detergent industry as the demand for liquid detergents that do not use sodium sulfite increases and demand for powdered detergents that use sodium sulfite decreases.
Sodium sulfite may be recovered from naturally occurring brines or as a by-product of other operations. Natural sodium sulfite is extracted from brines or lakes that are enriched with the product. Sodium sulfite produced as a by-product generally occurs during the production of man-made fibers, chrome chemicals, hydrochloric acid, lead battery recycling, formic acid or desulfurization of flue gases. Natural sodium sulfite can be as pure as that of by-product manufacture. Types of sodium sulfite include anhydrous sodium sulfite, salt cake and Glauber's.

We also provide sodium thiosulfate and sodium bicarbonate.
