Phosphate is one of the main downstream demand products of phosphoric acid, accounting for more than 30%, is one of the natural components of almost all foods, and is widely used in food processing as an important food ingredient and functional additive. China's phosphate and phosphoric acid products are abundant and the production scale is large. There are about 100 varieties and specifications of phosphate and phosphide products, and Zongsheng's production capacity is nearly 10 million tons. The main products are phosphoric acid, sodium tripolyphosphate, sodium hexametaphosphate, feed phosphate, phosphorus trichloride, phosphorus oxychloride, etc.

At present, the demand for traditional bottom phosphate products in China is sluggish, and traditional phosphates such as sodium tripolyphosphate will cause the problem of "eutrophication" in the waters, and the content of sodium tripolyphosphate in laundry detergent is gradually declining. However, on the other hand, the demand for refined and special phosphorus chemical products such as medium and high-grade phosphoric acid and phosphate (electronic grade, food grade), compound phosphate, and organophosphate has grown rapidly.
