Responsible Minerals Initiative (RMI) - Responsible Minerals Assurance Process A-4: All Minerals Step 4: independent third-party assessment

The company must permit an independent assessment by a third party of its supply chain due diligence activities and processes, be prepared with relevant documentation samples, and give assessors access to sites, personnel and all relevant records; an RMAP assessment against this standard satisfies OECD Step 4, and may be combined with ESG assessments with separate reports.
