Some of these minerals and/or derivatives can make their way into the supply chains of the products used around the world.

We don’t directly purchase any conflict minerals. Application metals: gold (Au), tantalum (Ta),tungsten (W), tin (Sn), cobalt (Co). But our products contain conflict minerals. In support of this sourcing policy, we will：

1. We make sure with venders that they are not using the minerals sourcing from the armed groups in the Eastern region of the Democratic Republic of Congo(DRC) and adjoining countries.

2. We make sure with venders that their suppliers are not using the minerals sourcing from the armed groups in the Eastern region of the Democratic Republic of Congo(DRC) and adjoining countries.
