Conflict Minerals Procurement Policy
Some metal minerals have become the main source of finance for armed rebel groups in the African Republic of Congo, which is used to trade arms, continue the bloody conflict between them and the government, and ravage the local civilian population, thus causing international controversy. As a citizen of the world, we declare and promise not to accept the use of metals from conflict mining areas. At the same time, we also require the suppliers of Hangzhou Kepsin:
1. Social and environmental responsibilities must be fulfilled;
2. Ensure that the products do not use "conflict minerals" from Congo and its neighboring countries and regions ";
3. Trace the source of gold (Au), tantalum (Ta), tin (Sn) and tungsten (W) contained in all products
4. Communicate this requirement to your upstream suppliers.
Conflict metals: Minerals from conflict mining areas in the Democratic Republic of the Congo, including niobium-tantalite, cassiterite, wolframite and gold. These minerals are refined into tantalum (Ta), tin (Sn), tungsten (W)(referred to as three T minerals) and gold (Au), respectively, for electronic and other products.
In the near future, the use of metals produced by certain smelters will be banned, so all key suppliers must trace the source and smelter of the metals used in their parts.
