The OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas provides a framework for companies to ensure they are sourcing minerals responsibly and not contributing to conflict, human rights abuses, or environmental degradation. These guidelines apply especially to minerals such as tin, tantalum, tungsten, and gold (often referred to as 3TG), which are commonly linked to conflicts in certain regions. The guidance outlines a five-step due diligence framework that helps companies identify, assess, and mitigate risks in their mineral supply chains.
The five steps include:
-
Establish strong company management systems – including a supply chain policy, internal control systems, and a grievance mechanism.
-
Identify and assess risk in the supply chain – mapping suppliers and evaluating potential risks associated with sourcing regions.
-
Design and implement a strategy to respond to identified risks – taking corrective actions and monitoring outcomes.
-
Carry out independent third-party audits of supply chain due diligence – particularly for smelters and refiners.
-
Report annually on supply chain due diligence – increasing transparency and accountability to stakeholders.
