The lab is owned and managed by QPI’s lab partner Hanse Control of Germany.

The major advantage with its location is that it is central within the Asian production centers, which include Vietnam, Laos and Bangladesh in the south as well as Taiwan, Shanghai, Shandong and Zhejiang, in the North.

Dongguan is located the Pearl River Delta region centrally within Guangdong, which is adjacent to Fujian.

Sending samples or test specimens within China is quicker, easier and much cheaper than sending to overseas labs, even compared with Hong Kong labs!
