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


Helping companies source minerals responsibly

The OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas provides detailed recommendations to help companies respect human rights and avoid contributing to conflict through their mineral purchasing decisions and practices. The Due Diligence Guidance is for use by any company potentially sourcing minerals or metals from conflict-affected and high-risk areas.

It is one of the only international frameworks available to help companies meet their due diligence reporting requirements.

The Guidance was officially adopted on 25 May 2011 at the OECD's 50th Anniversary Ministerial Meeting.

> Council Recommendation

> Remarks by US Secretary of State Clinton

> Statement by NGOs (pdf)

> Déclaration des ONG (pdf)

The Council Recommendation was revised on 17 July 2012 to include the Gold Supplement. While not legally-binding, the Recommendation reflects the common position and political commitment of adhering countries which include all 34 OECD countries, and 9 non-OECD countries (Argentina, Brazil, Colombia, Costa Rica, Latvia, Lithuania, Morocco, Peru, and Romania).

Simplified guide

This guide explains the basics of upstream due diligence in the supply chain of tin, tantalum, tungsten and gold from conflict-affected and high-risk areas in Africa’s Great Lakes region. It does not replace the official text of the Guidance.

An international standard

On 22 August 2012, the US Securities and Exchange Commission recognised the OECD Guidance as an international framework for due diligence measures undertaken by companies that are required to file a conflict minerals report under the final rule implementing sec 1502 of the Dodd-Frank legislation. Read the press release

The US Department of State endorses the Guidance and encourages companies to draw upon it as they establish their due diligence practices. Statement signed by Under Secretaries Hormats and Otero.

The United Nations Security Council resolution 1952 (2010) supports taking forward the due diligence recommendations contained in the final report of  the UN Group of Experts on the Democratic Republic of the Congo, which endorses and relies on the OECD Due Diligence Guidance.

The Lusaka Declaration [ français ] signed by 11 Heads of State of the International Conference on the Great Lakes Region (ICGLR) in December 2010 states the processes and standards of the OECD Due Diligence Guidance will be integrated into the six tools of the Regional Initiative against the Illegal Exploitation of Natural Resources. To intensify co-operation, a Memorandum of Understanding between the OECD and the ICGLR was signed on 13 December 2010. G8 leaders and African countries encouraged full implementation of the Lusaka Declaration at the Deauville G8 summit on 26-27 May 2011. G8/Africa joint declaration.


Implementing the Guidance

The Guidance was developed through a multi-stakeholder process with in-depth engagement from OECD and African countries, industry and civil society, as well as the United Nations Group of Experts on the Democratic Republic of Congo. The Guidance is a practical approach to due diligence implementation with an emphasis on collaborative, constructive solutions to complex challenges.

Work is underway to ensure the widest possible dissemination of the Guidance and its active use by companies throughout the mineral supply chain, industry associations, financial institutions, and civil society organisations. The OECD, the ICGLR and the UN Group of Experts on the DRC are working together to implement the Guidance in Africa's Great Lakes region as well as other parts of the world.

Specific minerals present unique challenges for supply chain due diligence. The Tin, Tantalum and Tungsten Supplement was developed at the same time as the Due Diligence Guidance in 2011. The Gold Supplement was developed subsequently and became an integral part of the Due Diligence Guidance in July 2012.
