After the State Drug Administration (SDA) was established in 1998, it took a firm hand in supervising China's pharmaceutical industry. SDA decided that all pharmaceutical manufacturers must meet GMP standards and obtain GMP certification before June 30, 2004. Since that time, guidances for the following products have been developed:
* biological products and blood products (Dec. 31,1999);
* powders for injection and infusion (Dec. 31, 2000);
* injectables (Dec. 31, 2002);
* all products (June 30, 2004).
