Traceability in mineral supply chains: from transparency to accountability

Traceability is rapidly becoming a strategic requirement in global mineral supply chains. Emerging regulations such as the EU Battery Regulation and the Corporate Sustainability Due Diligence Directive (CSDDD), alongside growing market expectations around ESG performance and responsible sourcing, are increasing pressure on companies to demonstrate where minerals originate, how they move through supply chains, and under which environmental and social conditions they are produced. For both companies and technology providers, traceability is increasingly linked to market access, regulatory compliance, and corporate credibility.

This deep dive examines how traceability is currently defined, implemented, and governed across mineral supply chains. It reviews recent policy developments, regulatory frameworks, chain-of-custody models, and the growing ecosystem of digital traceability tools, including blockchain-based systems, digital product passports, and material fingerprinting technologies. The analysis highlights that while technological capabilities are advancing rapidly, traceability remains fundamentally a governance challenge rather than a purely technical one.

• Traceability is becoming a market expectation: EU regulations and international initiatives increasingly require companies to demonstrate transparent and auditable supply chain information.
• Technology alone is not enough: Blockchain systems, digital product passports, and geoforensic tools can improve visibility and provenance verification, but they do not automatically guarantee responsible sourcing outcomes.
• Verified data matters: The effectiveness of traceability systems depends on data quality, independent verification, and credible chain-of-custody processes rather than self-declared information alone.
• Traceability must support risk-based due diligence: High-performing systems link traceability data to audits, grievance mechanisms, remediation workflows, and stakeholder engagement processes.
• Interoperability is becoming critical: Companies and tool providers increasingly need systems capable of exchanging data across platforms and regulatory environments.
• Implementation remains uneven: Upstream actors, including artisanal and small-scale mining (ASM), could face disproportionate compliance burdens and limited digital capacity.

The report shows that traceability systems can significantly improve supply chain visibility, support regulatory reporting, and strengthen due diligence processes. Many of the tools reviewed provide sophisticated functionalities for documenting provenance, tracking material flows, sharing ESG-related information, and supporting interoperability across supply chain actors. However, the analysis also reveals a central limitation: traceability alone does not guarantee responsible sourcing outcomes. If traceability systems merely confirm that minerals originate from operations associated with environmental harm, labour violations, corruption, or weak governance, they risk legitimizing problematic supply chains rather than transforming them.

As a result, the report argues that traceability should be understood not as an end goal, but as an enabling infrastructure for responsible sourcing and supply chain governance. Companies must move beyond symbolic transparency toward risk-based due diligence approaches integrating verified data, independent assurance mechanisms, stakeholder accountability, and remediation processes.

Finally, this deep dive highlights broader structural challenges surrounding traceability implementation. Regulatory expectations are often driven by downstream industries and importing regions, while compliance costs and reporting burdens frequently fall on upstream producers. Without investments in capacity-building, digital infrastructure, and inclusive governance approaches, traceability systems risk reinforcing existing inequalities within global mineral supply chains.

Ultimately, this report concludes that traceability is a necessary but insufficient condition for responsible mineral sourcing. Traceability can make supply chains more visible, auditable, and governable, but it cannot replace clear standards, effective due diligence, stakeholder engagement, or political decisions about acceptable sourcing practices. The central challenge is therefore not only to trace minerals, but to ensure that traceability systems meaningfully contribute to accountability, risk mitigation, and measurable improvements across mineral value chains.
