Dongcheng USA, a subsidiary of Yantai Dongcheng, Sino Siam Biotechnique Co., a manufacturer of chondroitin sulfate, has earned USP certification, according to John Turner, vice president. Sino Siam is also GMP, ISO9001 and HACCP certified.

Yantai Dongcheng Biochemical Co. Ltd., Shandong China, manufacturer of chondroitin sulfate, recently acquired Sino Siam Biotechnique Co. Ltd., Thailand, creating what the company claimed is the world’s largest supplier of chondroitin sulfate. Dongcheng USA now handles all the sales of chondroitin sulfate.

Sino Siam Biotechnique Co. Ltd. has a manufacturing capacity of 350 metric tons annually. “The approximate annual market for chondroitin in the U.S. is about 2,500 tons, and globally, that figure is about 4,000 tons,” Mr. Turner said.

“This acquisition can ensure that those needs are met, as consumers are still loyal to chondroitin to help support joint health. In addition, the quality control mechanisms and certifications achieved by the company will assure the highest quality ingredient.”
