Standards

The RMI defines standards for smelters and refiners that participate in the Responsible Minerals Assurance Process (RMAP). Our standards development process described in the RMI Standard and Assessment Criteria Development Procedure is guided by the ISEAL Standard Setting Code of Good Practice and includes extensive stakeholder consultations to ensure our standards are aligned with regulatory requirements, meet best practice expectations and are of high quality in a way that is verifiable and promotes the RMAP’s credibility and acceptance by our stakeholders.

In addition to the collaboration with industry experts and metal associations, our standards development process includes a public consultation on any major revisions. The RMI works with its multi-stakeholder Standards Advisory Group to review input received from stakeholders.

The full Assurance Standards Landscape graphic is available in English and Chinese.

Each standard is regularly reviewed and updated. Current standards can be accessed here:
