"In FY22, the

Devices team mapped high-risk materials, including tin, tantalum, tungsten and gold (“conflict minerals”) and cobalt throughout the supply chain to trace the smelters and refiners through which they were processed and worked to ensure conformance with the Responsible Mining Initiative’s Responsible Mining Assurance Process (RMAP). More information about mapping, smelters and refiners, and conflict minerals and cobalt used in Devices’ supply chains can be found in the Microsoft Devices Smelter and Refiner List and Microsoft’s 2022 Conflict Minerals Report."
