Conflict Materials and the Laws Regulating Them

Conflict materials refer to minerals sourced in a way that finances or supports armed conflict, human rights abuses, or violations of international law. In corporate supply chains, these minerals often include tin, tantalum, tungsten, and gold (collectively known as 3TG), as well as cobalt in some contexts. Governments worldwide have established regulatory frameworks to promote transparency, due diligence, and responsible sourcing. This article explains what conflict materials are, surveys the major legal regimes in the United States and internationally, and outlines practical steps for companies to comply and manage risk.

What Are Conflict Materials?

Conflict materials are minerals mined in conditions that contribute to human rights abuses or conflict. The most commonly referenced 3TG minerals originate from areas where mining profits support armed groups or corrupt actors, undermining social and economic development. Beyond 3TG, cobalt and other minerals can also become linked to conflicts when supply chains lack traceability. The goal of regulation is to require companies to identify, assess, and mitigate risk in their supply chains, ensuring responsible sourcing practices and improving visibility from mine to market.

Laws Regulating Conflict Materials

United States: Dodd-Frank Act and SEC Conflict Minerals Rule

The Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in 2010, directs the Securities and Exchange Commission to require public companies to disclose information about their use of conflict minerals. The accompanying rule, often referred to as the conflict minerals rule, requires issuers to determine whether minerals fund or trace back to armed conflict in the Democratic Republic of Congo or adjoining countries (the covered countries). If minerals originate or are used to fund conflict, companies must file a conflict minerals report with the SEC and include a description of due diligence measures performed.

Key requirements include: identifying the minerals used in products, conducting a reasonable country of origin inquiry, performing due diligence through a recognized framework, and reporting to shareholders. The rule emphasizes annual disclosure, not a blanket ban. While enforcement has evolved, the rule remains a cornerstone of U.S. regulatory efforts to curb financing of conflict through minerals. Many firms also align with a broader due diligence framework to manage supply chain risk and investor expectations.

International and Regional Frameworks

Global initiatives complement U.S. regulations by offering due diligence guidance, verification mechanisms, and traceability standards that multinational companies can apply across jurisdictions. Key frameworks include:

• OECD Due Diligence Guidance for Responsible Supply Chains of Minerals: A widely adopted, risk-based framework for identifying, preventing, and mitigating adverse impacts linked to mineral supply chains. It emphasizes governance, risk assessment, supplier engagement, and transparency.
• EU Conflict Minerals Regulation: A binding framework that requires importers of tin, tantalum, tungsten, and gold into the European Union to conduct due diligence and report on risk management. It focuses on the European market’s supply chain integrity and human rights protections.
• UK Modern Slavery Act and Australia’s Modern Slavery Act: These laws require organizations to disclose steps taken to prevent modern slavery in their operations and supply chains, which intersects with conflict minerals concerns when forced or child labor is involved.
• Canada’s Combating the Financing of Terrorism Act and related supply chain standards: Canadian regulations encourage ethical sourcing and supplier transparency in minerals across markets connected to conflict risks.

These frameworks vary in scope, enforcement, and geographic emphasis, but collectively promote due diligence, risk-based assessment, and supply chain transparency that benefit global trade and human rights protections.

Supply Chain Due Diligence and Verification Standards

Beyond jurisdictional rules, many organizations adopt due diligence standards to verify the origin of minerals. Verification often uses chain-of-custody documentation, third-party audits, and technical tools like blockchain traceability, independent lab assays, and supplier questionnaires. The goal is to reduce uncertainty about whether minerals originate from conflict zones, ensure responsible mining practices, and provide reliable information to customers, investors, and regulators.

Practical Implications For Companies

Regulatory obligations require a disciplined approach to supply chain management. The following practices help organizations align with laws and reduce risk:

• Establish a governance structure: Assign responsibility for conflict minerals policy, due diligence, and reporting at the board or executive level.
• Map the supply chain: Identify all direct suppliers and, where feasible, sub-suppliers, and determine the minerals used in products.
• Perform risk assessments: Use a risk-based approach to identify supply chains with elevated risk of funding conflict or labor abuses.
• Implement due diligence measures: Apply OECD-guided processes, perform country-of-origin inquiries, and maintain documentation of sourcing and supplier practices.
• Engage suppliers: Communicate expectations, provide training, and require evidence of responsible sourcing from suppliers and their sub-suppliers.
• Audit and verify: Conduct supplier audits or third-party verifications where feasible to validate information and compliance.
• Disclose and report: Prepare annual disclosures or reports in line with applicable laws, explaining due diligence steps and risk mitigation outcomes.
• Plan for remediation: Develop corrective action plans for suppliers that fail to meet standards and, when necessary, phase out non-compliant sources.

For U.S.-listed companies, the SEC conflict minerals rule remains central, but many corporations extend due diligence to align with OECD guidelines and EU or UK regimes, enhancing global credibility and reducing regulatory risk.

Key Takeaways

• Conflict materials are minerals whose sourcing finances conflict or violates human rights.
• 3TG minerals (tin, tantalum, tungsten, gold) are the most scrutinized due to their prevalence in electronics and jewelry supply chains.
• U.S. regulation centers on the Dodd-Frank Act’s conflict minerals rule, requiring disclosure of due diligence and mineral origin information for public companies.
• Global frameworks like the OECD Guidance and EU Conflict Minerals Regulation drive cross-border due diligence and supply chain transparency.
• Due diligence involves governance, risk assessment, supplier engagement, verification, and reporting to mitigate conflict financing and human rights risks.

In practice, multinational companies should harmonize internal policies to satisfy multiple regimes, develop robust supplier engagement programs, and maintain auditable records. The regulatory landscape continues to evolve, especially as more jurisdictions adopt or update conflict minerals and human rights provisions. Firms that integrate comprehensive due diligence with transparent reporting typically achieve stronger investor confidence, improved risk management, and better alignment with global sourcing expectations.
