In order to fulfill social responsibilities and to comply with CSR projects, we must cooperate with our complete supply chain specifications and management measures. In response to global resistance to mineral conflicts, Sun Jun is committed to not using conflict minerals and does not accept primary minerals (coltan, cassiterite, wolframite and gold from the Congolese and neighboring conflict countries in Central Africa, etc.) and these minerals are extracted into tantalum (Ta), tin (Sn), tungsten (W), cobalt (Co), mica(Mi) and gold (Au) for use in electronics or other products. Suppliers are also strongly urged to provide “conflict-free mineral guarantees” to avoid the use of conflict minerals in the raw materials provided.
