With more than 500 member companies, the Responsible Minerals Initiative (RMI) is one of the world’s largest industry associations focused on advancing responsible mineral sourcing across global supply chains. The RMI supports comprehensive due diligence ecosystem through leading standards for smelters, refiners and recyclers, data, and collaborative actions across minerals supply chains.

The RMI serves as a bridge between upstream and downstream companies, facilitating accountability and transparency through third-party assessments, facility data, and reporting on minerals due diligence.

The RMI's management systems approach is designed to validate conformance to standards for progressive due diligence, to help improve practices and support compliance with major regulatory frameworks worldwide. 

The RMI does not validate minerals, material or mines. Founded in 2008 and an initiative of the Responsible Business Alliance (RBA), the RMI is experienced in helping companies build more responsible, resilient, and transparent mineral supply chains.
