Tianjin Chengyi International Trading Co., Ltd a chemical and pharmaceutical company established in 1999, headquartered at the National Hi-Tech Industrial Development Area of Taiyuan City, Shanxi Province, China.

When we started our company, we functioned as the Foreign Trade Corp. of Shanxi Yuanping Chemicals (Oxalic Acid & derivatives, Formic Acid & derivatives, Acetates) and Foreign Trade Corp. of Yangquan Jingcheng Chemicals (Sulfamic Acid & Derivatives). We were and remain the sole marketers of the products produced by these factories on a worldwide basis.

Through our efforts and at the request of other Chinese chemical producers, over the past 16 years, not only are we actively exporting our own products, but also those of other Chinese manufactures to worldwide markets.
