Conflict metal: refers to the mineral from the conflict area of the democratic republic of the Congo, including niobium tantalite, cassiterite, wolframite and gold. These minerals are refined into tantalum (Ta), tin (Sn), tungsten (W), cobalt (Co) and gold (Au) for use in electronics and other products, respectively.

Some metals have become a major source of revenue for armed rebel groups in the democratic republic of Congo, generating international controversy as they trade arms, perpetuate bloody conflicts with the government and ravage local civilians. As citizens of the world, we declare and promise not to accept the use of metals from conflict zones. Meanwhile, the supplier of sichuan dongge technology is required to:

1. Must fulfill social and environmental responsibilities;

2. Ensure that the products do not use "conflict minerals" from Congo and surrounding 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 supplier.

Hereby declare!
