Conformant Smelter Sourcing Information

This list includes the names and mineral sourcing for smelters and refiners that are Conformant with the Responsible Minerals Assurance Process (RMAP) Standards. These smelters and refiners have been validated by a third party auditor. RMAP auditors substantiate materials by reviewing documents in accordance with the requirements specified in the standards. It is the auditor's discretion to validate receipts until reasonable assurance has been achieved. Auditors use a sampling approach for materials for which there are no OECD red flags in the supply chain. 100% of material receipts are reviewed for materials in supply chains where red flags are identified. The "Indirect Supplying Smelter Sourcing” column indicates the aggregate material sourcing of the RMAP Conformant Smelters from which the purchasing smelter buys. The Purchasing Smelter may not necessarily purchase materials from each of their Supplying Smelters’ sourcing categories. The information provided herein represents the mineral origin where the minerals originate from a conflict-affected or high- risk area. For conformant smelters from RJC or LBMA, the sourcing has been confirmed by auditors of those programs.
