China to control quality of raw materials
BEIJING — China’s State Food and Drug Administration (SFDA) required manufacturers of dietary supplements to tighten the control of raw materials in a circular issued on Friday.
Manufacturers are now required to review the qualifications of raw material suppliers and inspect the production of suppliers regularly,the SFDA said in the circular.The suppliers must improve the quality control of raw materials and manufacturers should develop a detailed record of raw material purchases so that the sources of raw materials can be easily tracked,the document said.The SFDA also asked its local branches to tighten the supervision of manufacturers who use expensive and rare extractions from animal and plants and imported raw materials.Manufacturers that use substandard raw materials to produce dietary supplements will be seriously punished,the document said.
