We are the largest producer of ammonium sulfite and the second largest producer of ammonium bisulfite in China. We have been serving the paper industry and chemical industry since 2007. Our chemicals are used in the sustainable manufacture of paper from waste materials such as straw.


In 2013, we acquired the Ogistar, Changyun and Qiaoke lubricant oil brands and started to produce high grade lubricants for the automotive market and oil production market.


We are based in Shandong province in eastern China, close to several chemical plants and paper making factories. Shandong province is rich in downstream industries and occupies the top position nationally for production output for the chemical engineering, paper pulp, food and pharmaceutical industries, and the second position nationally for paper output.
