Due Diligence Guidance on Conflict Minerals

The Conflict-Free Sourcing Initiative offers resources for companies about best practice, guidance, and standards on conducting due diligence on minerals from conflict-affected and high-risk areas, regulatory compliance, and public reporting. Many of these documents are authored by our members with contributions from stakeholders.

For all guidance documents, please note that any clarification by the U.S. Securities and Exchange Commission (SEC) or OECD would supercede the guidance provided here.
