RMI Responsible Minerals Assurance Process (RMAP) Tin and Tantalum Standard

The Responsible Minerals Assurance Process (RMAP) was established to cultivate transparent mineral supply chains and sustainable corporate engagement in the mineral sector with a view to prevent the extraction and trade of minerals contributing to or being associated with significant adverse impacts, including serious human rights abuses, money laundering and conflict. The RMAP Tin and Tantalum Standard was developed as a specific, practical framework to consistently audit the operations and practices of tin and tantalum smelters, the point at which mineral is converted into a generic metallic powder, product or compound. It follows guidance provided by the final report of the UN Group of Experts to the Security Council on 15th November 2010, and by the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.
