What Are Conflict Minerals and What Do CSDDD Due Diligence Rules Require of Businesses in 2026?

Your smartphone may carry a hidden cost. Your electric vehicle might share a similar burden. Even the jewellery in your drawer may come with a price measured not in dollars, but in human lives. Conflict minerals are raw materials extracted in conflict zones and sold to finance armed groups and militias, a trade that fuels decades of violence, particularly across Central Africa. Understanding conflict minerals is no longer a matter solely for policymakers and NGOs. It is a pressing compliance obligation for businesses, investors, and supply chain professionals operating under the EU Conflict Minerals Regulation, the US Dodd-Frank Act, the EU’s Corporate Sustainability Due Diligence Directive (CSDDD), the Corporate Sustainability Reporting Directive (CSRD), and growing Responsible Sourcing requirements globally.

What Are Conflict Minerals and Why Are They a Corporate Sustainability Priority?

Conflict minerals are natural resources extracted in conflict zones and sold to finance armed groups and perpetuate violence, generating environmental destruction, forced labour, and systematic human rights abuses in the process. The term most commonly refers to the 3TG minerals: Tin (cassiterite), Tantalum (coltan), Tungsten (wolframite), and Gold, originating primarily in the Democratic Republic of Congo (DRC) and adjacent countries. For businesses, conflict minerals represent an intersection of legal compliance obligations, Responsible Sourcing commitments, Human Rights Due Diligence requirements under CSDDD, and Scope 3 supply chain sustainability risks that must be disclosed under CSRD/ESRS S2 (Value Chain Workers) and ESRS E4 (Biodiversity and Ecosystems) where material.

What Are the Human Rights and Environmental Consequences of Conflict Mineral Extraction?

The human cost of conflict mineral extraction is severe. In the DRC, resource-driven conflicts have caused an enormous loss of life and mass displacement. Armed groups often control mining operations and deploy forced labour, including child labour. This practice violates ILO Core Labour Standards. Environmentally, artisanal and small-scale mining (ASM) in the Congo Basin rainforest leads to deforestation and soil erosion. It also causes fluvial contamination, impacting biodiversity and ecosystem services that must be disclosed under CSRD/ESRS E4 where material. The sustainability cost of conflict minerals is high. It includes environmental degradation, economic extraction without community benefits, and systematic social harm. This makes conflict minerals a defining test case for integrated sustainability governance.

Which Industries Face the Greatest Conflict Mineral Compliance Exposure?

Electronics and Technology: Why Is 3TG Exposure Highest Here?

Consumer electronics account for the highest volume of conflict mineral exposure. Tantalum (coltan) is used in capacitors in virtually all smartphones, laptops, and tablets. Tin is used in circuit board soldering. Leading technology companies such as Apple, Samsung, and Intel have faced regulatory scrutiny. They have engaged with investors concerning 3TG sourcing. This scrutiny drives the adoption of Responsible Minerals Initiative (RMI) smelter verification programmes. It also encourages the use of chain-of-custody documentation. Increasingly, companies are preparing Digital Product Passport infrastructure. This infrastructure is designed to provide end-to-end material traceability at the product level once the relevant delegated acts apply.

Automotive and Electric Vehicles: Why Is the Conflict Mineral Risk Expanding?

The accelerating transition to battery electric vehicles (BEVs) is expanding conflict mineral risk beyond classical 3TG to include cobalt, lithium, and nickel, materials central to lithium-ion battery chemistries. Artisanal cobalt mining in the DRC involves child labour at industrially significant scale. Lithium extraction in the Atacama raises concerns about water stewardship and indigenous community rights. These risks fall squarely within the scope of Human Rights Due Diligence under CSDDD, Responsible Sourcing disclosure under CSRD/ESRS S2, and TNFD Alignment under ESRS E3 (Water and Marine Resources) and ESRS E4 (Biodiversity). Batteries also have their own EU rules, including due diligence obligations under the EU Battery Regulation.

Jewellery and Luxury Goods: How Is Gold Traceability Being Addressed?

Gold sourced from conflict zones frequently enters global markets through informal trading networks characterised by multi-tier opacity. Fairtrade Gold certification and the Responsible Jewellery Council (RJC) Code of Practices provide recognised assurance frameworks. For luxury brands in scope of CSDDD, robust chain-of-custody documentation from licensed gold exporters is the minimum Human Rights Due Diligence threshold, with supply chain disclosure required under CSRD/ESRS S2 and ESRS G1 for companies in scope.

What Regulations Govern Conflict Mineral Due Diligence for Businesses?

What Does Dodd-Frank Section 1502 Require from US-Listed Companies?

The Dodd-Frank Act Section 1502 (2010) requires US SEC-registered companies to disclose annually whether their products contain 3TG minerals originating from the DRC or its nine neighbouring countries. Where DRC origin is confirmed or cannot be ruled out, companies must file a Conflict Minerals Report (CMR) documenting due diligence measures applied against the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.

What Does the EU Conflict Minerals Regulation 2017/821 Require?

The EU Conflict Minerals Regulation has been in force since January 2021. It obligates EU-based importers of 3TG minerals and metals above defined volume thresholds to conduct OECD-aligned supply chain due diligence. The process covers risk identification, risk mitigation, third-party audits of smelters and refiners, and public disclosure of due diligence policies. Unlike Dodd-Frank, the EU Regulation applies at the point of import into the EU market. It covers a broader set of actors in the supply chain. Additionally, it is designed to interface directly with CSRD/ESRS S2 value chain disclosure requirements for companies in scope.

How Does the EU CSDDD Elevate Conflict Mineral Due Diligence Beyond Existing Rules?

The EU Corporate Sustainability Due Diligence Directive (CSDDD) elevates conflict mineral obligations beyond targeted regulatory disclosure, although its scope is narrower than first planned. Omnibus I, Directive (EU) 2026/470, limited it to companies with more than 5,000 employees and more than EUR 1.5 billion in net worldwide turnover. Member States must transpose it by July 26, 2028, and it applies from July 26, 2029, with fines capped at 3% of net worldwide turnover. In-scope organisations must conduct risk-based Human Rights Due Diligence across their value chains. They need to identify, prevent, mitigate, and account for actual and potential adverse human rights impacts. For mineral-intensive supply chains, this involves formalised supplier risk assessment. It also includes contractual Human Rights Due Diligence clauses and documented remediation processes for identified violations. These obligations go substantially beyond smelter audit programmes. Smaller suppliers will still feel the effect, because in-scope buyers pass requirements down their supply chains.

What Does Responsible Sourcing and Digital Traceability Look Like in Practice?

Leading organisations are developing conflict mineral compliance programmes that exceed regulatory minimums. The Responsible Minerals Assurance Process (RMAP) is managed by the Responsible Minerals Initiative (RMI). It provides validated compliance status for hundreds of smelters and refiners worldwide. Blockchain-based traceability pilots such as Everledger (gold) and Circulor (cobalt, tantalum) enable mine-of-origin verification at scale. Digital Product Passports will become mandatory under the EU’s Ecodesign for Sustainable Products Regulation (ESPR) product group by product group once delegated acts apply, and the EU passport registry has been live since July 20, 2026. They create a framework for embedding material traceability data in product disclosures. This develops a direct link between Responsible Sourcing commitments and verifiable product evidence. For organisations conducting LCSA, S-LCA inventory analysis of mineral supply chains offers a robust method. It quantifies social impacts at the source. This supports the evidence requirements for Human Rights Due Diligence under CSDDD.

What Can Consumers and Procurement Teams Do About Conflict Minerals?

• Ask questions: Engage brands directly about their conflict minerals policies and CSDDD due diligence programmes.
• Choose certified products: Look for Fairtrade Gold certification or electronics brands with strong RMI participation and published Conflict Minerals Reports.
• Support advocacy: Organisations such as Global Witness and Amnesty International campaign for stronger mineral supply chain laws and CSDDD enforcement.
• Recycle electronics: Proper e-waste recycling reduces demand for newly mined 3TG materials and supports Circular Economy KPI targets.

What Is the Road Ahead for Conflict Mineral Governance?

The conflict minerals challenge is far from solved. The green energy transition and the proliferation of smart devices are driving surging demand for critical minerals, intensifying pressure on vulnerable mining regions. Emerging concerns now extend well beyond 3TG to cobalt, lithium, and nickel, central to battery supply chains and subject to documented human rights and Water Stewardship failures in extraction geographies. Tighter international regulation, greater investment in mine formalisation, and genuine corporate accountability, driven by CSDDD enforcement and CSRD/ESRS S2 disclosure obligations for the companies they cover, are the necessary conditions for progress. Conflict minerals represent the point at which social sustainability, material flows, Scope 3 decarbonisation strategies, and governance intersect most acutely.
