Guidelines for multinational enterprises

Implementing the OECD Due Diligence Guidance


A combination of political, consumer, regulatory pressures and stakeholder engagement has enabled impressive uptake of the Due Diligence Guidance since its adoption in 2011. Although the Guidance is global in scope and applicable to all minerals, the OECD’s implementation programme currently focuses on the tin, tantalum, tungsten (3Ts) and gold supply chains. The programme comprises over 500 stakeholders from governments, international organisations, the private sector, local and international civil society, and experts.


This programme helps foster peer-learning, constructive dialogue and mutual understanding of due diligence practices and associated challenges across the gold supply chain. Gold presents specific challenges due to the nature of the commodity and in particular its high value-to-volume ratio.


Gold supply chain assessments

These assessments analyse gold supply chains in Africa's Great Lakes region. They cover stakeholder awareness of supply chain risks, the Due Diligence Guidance, the level of implementation of company due diligence initiatives and related government initiatives. They draw out strategic recommendations on how to advance responsible sourcing in the gold sector to ultimately make a positive contribution to socio-economic development of producer countries and communities.

  • Colombia's gold supply chain

This series of assessments on Colombian gold supply chains analyses the conditions of mineral extraction and related risks in Colombia as a whole and by region.


  • Burkina Faso, Mali and Niger

This assessment promotes the responsibility of economic actors, and the traceability and transparency of supply chains of gold ores produced in the LGA Member countries.


  • Gold industry initiatives guide

The Gold Industry Initiatives Guide demonstrates how the different industry-led codes and standards complement each other and operationalise the Due Diligence Guidance.


Gold sourcing supply chain webinars

The OECD and industry peers organised a  targeting different actors in the gold sourcing supply chain to demystify how to implement the responsible sourcing of gold.


  • Support to artisanal and small-scale miners

One of the main areas of OECD's work in the responsible sourcing of minerals is to ensure that international standards do not further marginalise workers of the informal sector. This implies working on the formalisation of Artisanal and Small-Scale Mining (ASM).



Similar to the gold programme, the 3T implementation programme helps foster peer learning and constructive dialogue.

The OECD conducted a 3T pilot survey in 2012 to assist companies implementing the Due Diligence Guidance to learn from each other’s experiences and share best practices. Over 110 upstream and downstream companies participated in the survey and six reports were produced.

Individual companies bear the primary responsibility for implementation of due diligence, although they may use industry programmes and initiatives to assist them in specific due diligence tasks. A number of initiatives have been developed by companies and industry associations to help companies implement due diligence, particularly to help them establish traceability or chain of custody systems, and to identify, assess and manage risk.
