ChoiceChem is a leading chemical company with its own factories and strong partnerships. We are the second-largest producer of sodium metabisulfite in China and an OEM partner for BASF. Our production process involves creating sodium metabisulfite, sodium sulfite, and sodium bisulphite, during which we collect SO2 gas. This gas is then used to produce magnesium sulfate (MGSO4) and sulfate of potash (SOP) through a reaction with magnesite and potassium chloride. Thanks to the almost free cost of sulfuric acid in this process, our MGSO4 and SOP are cheaper than competitors. We also have food-grade and pharmaceutical-grade production licenses, meaning our products are suitable for fertilizers, food, and pharmaceutical applications.
