OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas


 Helping industries meet responsible sourcing expectations
The OECD Due Diligence Guidance provides detailed recommendations to help companies respect human rights and avoid contributing to conflict through their mineral purchasing decisions and practices. This Guidance is for use by any company potentially sourcing minerals or metals from conflict-affected and high-risk areas. The OECD Guidance is global in scope and applies to all mineral supply chains.


The 3rd Edition of the OECD Due Diligence Guidance was published in April 2016. This booklet contains the OECD Council Recommendation, the text of the Guidance, the 3Ts Supplement and the Gold Supplement. The updated version clarifies that the Guidance provides a framework for detailed due diligence as a basis for responsible supply chain management of minerals, including tin, tantalum, tungsten and gold, as well as all other mineral resources. In addition to the 37 OECD Members, 9 non-Members, namely Argentina, Brazil, Costa Rica, Croatia, Kazakhstan, Morocco, Peru and Romania and Ukraine, adhered to the Council Recommendation.
