“The blood in your battery.” Conflict minerals are natural resources extracted in zones of armed conflict and sold to finance warring factions — with their supply chains embedded in global electronics, automotive, and jewelry manufacturing.
Executive Summary
The term “conflict minerals” originated with the Dodd-Frank Act’s Section 1502 (2010), which required U.S.-listed companies to disclose whether their products contain tin, tantalum, tungsten, or gold (the “3TGs”) sourced from the Democratic Republic of Congo or adjoining countries. But the concept has expanded significantly in scope: cobalt (essential for EV batteries), coltan, lithium, and rare earth elements extracted in politically unstable or conflict-affected regions have entered the conflict minerals conversation as the energy transition massively expands demand for critical minerals. By 2025, conflict mineral compliance has become a mainstream corporate governance obligation — and a strategic supply chain risk as the geopolitics of critical mineral sourcing intensifies.
The Strategic Mechanism
- The 3TG framework: Tin (solder in electronics), tantalum (capacitors in smartphones and laptops), tungsten (vibration motors), and gold (connectors and plating) are the original Dodd-Frank 3TGs. The DRC and its neighbors contain extraordinary concentrations of these materials, mined partly under conditions of armed group control.
- Cobalt and the EV expansion: The DRC produces approximately 70% of global cobalt, much of it through artisanal mining operations with documented forced and child labor. As cobalt demand for lithium-ion battery cathodes surged with EV adoption, cobalt supply chain risk became a board-level issue for Apple, Tesla, Samsung, and every major EV manufacturer.
- Supply chain opacity: The conflict minerals supply chain is notoriously difficult to trace: minerals change hands multiple times between artisanal miners, local traders, regional smelters, and international refiners before reaching manufacturers. The OECD Due Diligence Guidance for Responsible Supply Chains provides the global standard framework, but implementation is voluntary in most jurisdictions.
- EU Conflict Minerals Regulation (effective 2021): Mandatory due diligence requirements for EU importers of 3TGs above volume thresholds — requiring supply chain audits, risk assessment, and disclosure. The EU regulation applies to importers of raw materials, not downstream manufacturers.
- Critical minerals and the conflict nexus: The energy transition’s insatiable demand for lithium, cobalt, nickel, manganese, and rare earths has elevated the governance of extraction in politically fragile states — DRC, Myanmar, Zimbabwe, Mozambique — to a strategic priority for Western governments, not merely a compliance obligation for corporations.
Market & Policy Impact
- Apple, Samsung, and other major electronics brands have spent hundreds of millions developing cobalt supply chain tracing systems, with Apple announcing a goal of eliminating mined cobalt from its supply chain entirely through battery chemistry transition — a technology-driven solution to a governance problem.
- The DRC’s decision to suspend cobalt exports briefly in 2024 — in a dispute over mining royalties and processing requirements — triggered immediate supply chain risk alerts across the EV industry, illustrating how conflict mineral dependency creates state leverage.
- Tesla, BMW, and other EV makers have signed direct long-term supply agreements with DRC mining operators, attempting to vertically integrate backward into the supply chain to achieve traceability — but exposing themselves to political risk in one of the world’s least stable states.
- The SEC’s conflict minerals rule (Section 1502) faced ongoing legal and political challenges through 2024–2025, with the Trump administration’s deregulatory posture creating uncertainty about continued enforcement — diverging from the EU’s tightening trend.
- Myanmar’s coup in 2021 created a new conflict minerals flashpoint: the country is a major producer of rare earth elements, jade, and tin, with military junta control over extraction generating Western import compliance concerns.
Modern Case Study: DRC Cobalt and the EV Supply Chain Dilemma (2023–2025)
The electric vehicle transition’s dependence on DRC cobalt created a paradox at the heart of ESG-driven corporate strategy: the minerals needed to decarbonize transport were being extracted under conditions that violated the same human rights and governance standards that ESG frameworks require companies to uphold. Apple’s decision to transition iPhone batteries away from cobalt-containing cathode chemistry (toward lithium iron phosphate) was simultaneously a supply security move and an ESG de-risking play — but left the broader EV industry, which still depends on high-energy-density cobalt-nickel cathodes, without an equivalent exit option. The episode drove substantial investment in battery chemistry alternatives (sodium-ion, iron-air, solid-state) precisely to escape what one Ford executive called the “cobalt trap” — the structural inability to scale green transport without funding governance failures in one of the world’s most conflict-affected states.
