An international standard

In 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. The US Department of State endorses the Guidance and encourages companies to draw upon it as they establish their due diligence practices.
