Consultancy Firms

The Responsible Minerals Initiative provides this list of consultancy firms that are willing and capable to assist with the implementation of the OECD Due Diligence Guidance. The listed service providers are familiar with the issue of responsibly sourced minerals, due diligence, reporting and compliance, and/or have familiarity with in-region transportation/trade paths and issues, and familiarity with the goals of the existing in-region assurance schemes (ITSCI, Better Sourcing Program).

The RMI is providing this as a service to interested stakeholders and does not endorse or make any claims about the products or services of these providers or their website links. If your company is interested in being included on this list, please contact

Note that per the OECD Guidance, any firm a company chooses to validate their due diligence practices should not be the same firm that helped develop assurance schemes utilized by the company.
