What does battery due diligence mean?
Battery due diligence under the EU Battery Regulation is a structured set of obligations for economic operators covering their management systems, risk management processes, third-party verification, and public disclosure — specifically aimed at identifying, preventing, and addressing social and environmental risks in the sourcing and processing of raw materials and secondary raw materials for batteries. It applies to the supply chain of the battery itself (including suppliers, subsidiaries, and subcontractors), not just the direct operations of the economic operator.

EU Battery Regulation
Regulation (EU) 2023/1542 concerning batteries and waste batteries
the obligations of an economic operator in relation to its management system, risk management, third-party verifications and surveillance by notified bodies and disclosure of information, for the purpose of identifying, preventing and addressing actual and potential social and environmental risks linked to the sourcing, processing and trading of the raw materials and secondary raw materials required for battery manufacturing, including by suppliers in the chain and their subsidiaries or subcontractors;

Key deadline
Due diligence obligations apply from 18 August 2025 for EV and industrial batteries ≥ 2 kWh.
Practical application
Battery due diligence obligations apply to producers of EV batteries, industrial batteries ≥ 2 kWh, and SLI batteries (with thresholds TBD for LMT). The obligations extend well beyond procurement — they include establishing a management system, identifying risk areas (with specific focus on conflict-affected and high-risk areas), implementing risk-response plans, commissioning independent third-party audits, and publishing annual due diligence reports. Companies that treat this as a checkbox exercise rather than a systematic programme face verification and audit failure risks.
Minespider commentary
For Minespider, battery due diligence is the regulatory demand that turns supply chain traceability into a legal necessity rather than a nice-to-have. The ability to trace raw materials — particularly cobalt, lithium, nickel, manganese, and natural graphite — back through the supply chain to origin is a prerequisite for any credible risk assessment under this framework.
Common confusions
- Treating battery due diligence as equivalent to CSDDD due diligence — they overlap in concept but differ in scope, trigger thresholds, and specific requirements. Both may apply to the same company simultaneously.
- Assuming due diligence only covers Tier 1 suppliers — the Regulation explicitly extends obligations to suppliers in the chain and their subsidiaries and subcontractors.
- Confusing due diligence reporting with carbon footprint reporting — both are Battery Regulation obligations but they are separate data tracks with separate timelines and methodologies.
- Overlooking the OECD Minerals Guidance alignment — the Battery Regulation's due diligence framework is designed to align with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.
