Our approach to Conflict Minerals

Armed groups operating in the eastern Democratic Republic of the Congo (DRC) have engaged in conflict and severe human rights abuses, fueled through proceeds from the mining or trade of so-called “conflict minerals” or 3TGs (tin, tantalum, tungsten and gold).
These atrocities led to the creation of the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, the US Dodd–Frank Act and other international standards. Companies are expected to source responsibly from these areas to avoid a de facto embargo, and certain companies are required to disclose their due diligence consistent with the OECD Guidance, mitigating the risk that the 3TGs they purchase may directly or indirectly fund conflict in the DRC, adjoining countries, or other high-risk areas of the world.
SUMITA is committed to responsible sourcing of 3TGs, and collaborating with our customers and suppliers to promote responsible business practices. SUMITA is tracking the metal back to the smelter and mine of origin and providing data related to the origin of 3TGs by working with our customers and suppliers.
