State-designated Site

In April 2003, with approval under document S.J.F. [2003] No. 108 issued by the Development Planning Bureau of Siyang County, Jiangsu Province, 10 mu of land located in the Siyang Economic Development Zone was purchased for capacity expansion. The expanded factory was completed and began production in August 2004. It is located in the east part of the development zone at the intersection of Songhuajiang Road and Beijing East Road. The new manufacturing plant successfully passed an additional ‘‘State-designated site’’ audit by the MIIT Technical Materials Division in 2006.
