RMAP (Responsible Minerals Assurance Process)

The Responsible Minerals Assurance Process (RMAP) is the third-party audit program operated by RMI to verify that smelters and refiners of tin, tantalum, tungsten, and gold have systems in place to ensure responsible sourcing from conflict-affected and high-risk areas. RMAP audits assess whether smelters can demonstrate that their mineral inputs do not finance armed groups. Smelters that pass an RMAP audit are classified as ‘conformant.’ On October 16, 2025, the European Commission formally recognized RMAP as equivalent to EU Conflict Minerals Regulation (EU) 2017/821 requirements via Implementing Decision (EU) 2025/2071.

RMAP is the cornerstone of practical conflict minerals compliance. Downstream manufacturers cannot realistically audit every mine in their supply chain — instead, they rely on RMAP to verify responsible practices at the smelter level. Companies should: (1) collect CMRT data to identify all smelters; (2) check each smelter against the RMAP conformant/active list; (3) engage non-conformant smelters to pursue RMAP certification; (4) document RMAP verification in their conflict minerals records. The RMAP list is embedded in every CMRT version’s Standard Smelter List.

A tantalum refiner undergoes an RMAP audit conducted by an approved third-party audit firm. The audit assesses the refiner’s upstream due diligence including sourcing documentation, site visit records, and chain-of-custody controls. The refiner passes and receives conformant status for tantalum. All downstream manufacturers using this refiner can now reference its RMAP conformance in their conflict minerals disclosures.
