Conflict Minerals: Definition, Compliance Requirements, and Implementation in Procurement
March 30, 2026
Conflict minerals are raw materials from conflict-affected areas whose extraction and trade finance armed conflicts or promote human rights abuses. These minerals – primarily tin, tantalum, tungsten, and gold – present purchasing organizations with complex compliance challenges. Below, learn what conflict minerals are, which legal obligations apply, and how to make your supply chain transparent and responsible.
Key Facts
- Conflict minerals include the four main minerals tin, tantalum, tungsten, and gold (3TG)
- US and EU regulations require companies to disclose information and conduct due diligence
- Main mining areas are located in the Democratic Republic of the Congo and neighboring countries
- Affected industries include electronics, automotive, jewelry, and medical technology
- Compliance requires full supply chain traceability back to the mine
Content
What are conflict minerals?
Conflict minerals are raw materials whose extraction and trade in conflict-affected areas contribute to the financing of armed groups or cause serious human rights abuses.
The four main minerals (3TG)
The regulations focus on four critical minerals:
- Tin (Tin): Used in solder and electronic components
- Tantalum: Capacitors in smartphones and computers
- Tungsten (Tungsten): Carbide tools and filaments
- Gold: Electronic contacts and jewelry
Conflict minerals vs. critical raw materials
While critical raw materials primarily concern security of supply, conflict minerals focus on ethical and social aspects. The overlaps require integrated sourcing strategies that take into account both availability and Procurement Compliance.
Importance of conflict minerals in procurement
Procurement organizations must review and document their entire supply chain for conflict minerals. This requires close collaboration with suppliers, comprehensive Due Diligence, and transparent reporting to stakeholders and regulatory authorities.
Implementation, obligations, and documentation
Compliance with conflict minerals regulations requires systematic processes to identify, assess, and document the origin of minerals throughout the entire supply chain.
Reasonable Country of Origin Inquiry (RCOI)
Companies must first determine whether their products contain conflict minerals and could originate from affected regions. This initial assessment includes:
- Product analysis and material composition
- Supplier surveys using standardized forms
- Risk assessment based on geographic criteria
Conflict Minerals Due Diligence
If the RCOI result is positive, comprehensive due diligence is required. The process follows the OECD guidelines and includes supplier audits, Conflict Minerals Country of Origin Certificate, and continuous monitoring of the supply chain.
Reporting and documentation
Listed US companies must submit Form SD to the SEC annually. EU importers need certificates of conformity and must document their Corporate Sustainability Due Diligence (CSDDD). The reports contain detailed information on smelters, refiners, and countries of origin.
Compliance KPIs & documentation for conflict minerals
Effective conflict minerals programs require measurable metrics to monitor compliance performance and continuously improve due diligence processes.
Supply chain coverage and traceability
Key KPIs include the share of suppliers with complete CMRT documentation (Conflict Minerals Reporting Template) and traceability to the smelter. Target values are 100% coverage for critical suppliers and at least 95% identified smelters and refiners.
Audit and validation metrics
The quality of due diligence is measured using the following indicators:
- Share of audited smelters through recognized programs (RMI, LBMA)
- Average response time for supplier inquiries
- Number of identified and remediated compliance deviations
Cost-benefit analysis
Compliance costs are compared against the risks avoided. Typical metrics include compliance costs per product unit, ROI of due diligence investments, and cost savings through early risk identification. KYC in Procurement support the systematic assessment.
Risks, dependencies, and countermeasures
Non-compliance with conflict minerals regulations creates significant legal, financial, and reputational risks for companies and their supply chains.
Compliance and legal risks
Violations of conflict minerals regulations can lead to SEC sanctions, EU fines, and trade restrictions. Incomplete or incorrect reporting endangers stock exchange listing and may result in civil lawsuits from investors.
Supply chain disruptions
Dependence on only a few conflict-free sources significantly increases supply risks. Political instability in alternative mining areas can lead to price volatility and supply bottlenecks. Companies must develop diversified sourcing strategies and implement a Supplier Code of Conduct.
Reputational and market risks
Negative media coverage of conflict minerals in the supply chain can cause significant reputational damage. Consumers and B2B customers are increasingly demanding transparent and ethical sourcing. Whistleblower Reporting System and proactive communication are essential for risk management.

Practical example
A German automotive supplier is implementing a comprehensive conflict minerals program for its electronic components. The company first conducts an RCOI analysis for all products and identifies 150 suppliers with potential 3TG materials. Using standardized CMRT forms, origin data is collected and 85% of the smelters are successfully identified. On-site audits are carried out for critical suppliers, and alternative sourcing sources are qualified.
- Implementation of a digital tracking system for seamless documentation
- Training 50 buyers on conflict minerals compliance
- Establishment of an escalation process for non-compliance cases
Current developments and impact
The regulatory landscape for conflict minerals is evolving continuously, with stricter requirements and expanded scopes of application at the global level.
Expansion of the EU Conflict Minerals Regulation
Since 2021, the EU regulation has covered all importers of the four minerals above certain thresholds. Future expansions could include additional minerals and downstream companies, significantly broadening compliance requirements for German purchasing organizations.
Digitalization and blockchain technology
Innovative technologies are revolutionizing the traceability of conflict minerals. Blockchain-based systems enable seamless documentation from extraction to the end product, while AI-supported analyses automate risk assessments and improve Material Traceability.
Integration into ESG frameworks
Conflict minerals are increasingly being integrated into comprehensive ESG assessments. Rating agencies such as EcoVadis Rating consider conflict minerals compliance a key sustainability indicator, which has a direct impact on financing conditions and business relationships.
Conclusion
Conflict minerals compliance has become indispensable for modern purchasing organizations and requires systematic due diligence processes across the entire supply chain. Regulatory requirements are continuously becoming stricter, while innovative technologies are creating new opportunities for transparent traceability. Successful programs combine robust compliance structures with proactive supplier management and contribute to both risk minimization and sustainable value creation.
FAQ
Which companies are affected by conflict minerals regulations?
Listed US companies that manufacture products containing 3TG minerals, as well as EU importers above the thresholds (tin: 1t, tantalum: 1t, tungsten: 1t, gold: 100kg annually), must meet compliance requirements. Downstream companies are also indirectly affected through supplier requirements.
How does "conflict-free" differ from "DRC conflict-free"?
"DRC conflict-free" refers specifically to minerals that do not contribute to financing armed groups in the Democratic Republic of the Congo. "Conflict-free" is a broader term that may also include other conflict-affected areas and human rights abuses.
What costs arise from conflict minerals compliance?
Typical costs include due diligence processes (€50,000-200,000 annually), supplier audits (€5,000-15,000 per audit), IT systems for tracking (€20,000-100,000), and external consulting. Total costs vary considerably depending on the complexity of the supply chain and product portfolio.
How can traceability back to the mine be ensured?
Complete traceability requires multi-level approaches: supplier mapping, smelter identification through CMRT forms, third-party audits by recognized programs, and increasingly blockchain-based tracking systems. 100% traceability remains a challenge due to complex supply chains.
