EU Battery Regulation due-diligence readiness guide
A practical operating guide for economic operators placing batteries on the EU market getting ready for the Regulation (EU) 2023/1542 supply-chain due-diligence duties over cobalt, natural graphite, lithium, and nickel. It covers who is obligated, the policy, traceability, risk-management, notified-body verification, and public-reporting duties, and the parallel documentation demands surfacing in the United States. Due diligence applies from 18 August 2027, so the work to do now is building the evidence, not filing it.
Start the evidence work before the obligation lands
Supply-chain due diligence applies from 18 August 2027, postponed from 2025 by Regulation (EU) 2025/1561, so nothing is required today. The teams that fare best treat the intervening time as build time for policy, traceability, risk management, and verification, not a reason to wait.
Battery due diligence under Regulation (EU) 2023/1542 is not a document you file once. It is a standing evidence system over cobalt, natural graphite, lithium, and nickel that has to survive a notified body's audit and a public report every year.
EU Battery Regulation due-diligence map
Regulation (EU) 2023/1542 on batteries and waste batteries. It is a directly applicable EU Regulation, not a directive, so no national transposition is needed.
Cobalt, natural graphite, lithium, and nickel, plus the chemical compounds based on them that are needed to make battery active materials (Annex X).
Economic operators that place batteries on the EU market or put them into service. Operators with net turnover below EUR 40 million, and not part of a group above EUR 40 million on a consolidated basis, are exempt from the due-diligence duties.
Supply-chain due diligence applies from 18 August 2027, postponed from 2025 by Regulation (EU) 2025/1561. It is not required today, but the evidence work needs to be underway.
Due-diligence policies must be verified and periodically audited by a notified body. An internal sign-off or self-assessment does not satisfy Chapter VII.
Cobalt, lithium, nickel, and natural graphite are the battery materials under Annex X. Tin, tantalum, tungsten, and gold are governed separately under Regulation (EU) 2017/821 and are a different regime.
Dates to have on the calendar
The digital battery passport requirement begins. Each LMT battery, each industrial battery above 2 kWh, and each electric vehicle battery placed on the market or put into service from this date needs an electronic record; the passport is not retroactive to stock already on the market.
Chapter VII supply-chain due-diligence obligations apply, postponed from 18 August 2025 by Regulation (EU) 2025/1561. Policy, traceability, risk management, notified-body verification, and public reporting need to be operating by then, not just started.
Due-diligence action plan
Chapter VII turns four duties into ongoing evidence work: a due-diligence policy, a traceability system, risk management, and notified-body verification with public reporting. Use this sequence to have each one operating before 18 August 2027.
Confirm whether Chapter VII applies to you
Start by testing scope against the net-turnover threshold rather than assuming exemption. The exemption is narrow and does not touch the other duties in the Regulation.
Adopt and communicate a due-diligence policy
The policy is the anchor the notified body and the public report both draw from. It has to reach suppliers, not just sit in a binder.
Build the chain-of-custody and traceability system
Traceability has to identify upstream actors and origins, not stop at the immediate supplier. The evidence set is specified, so collect it in a structure a reviewer can follow.
Assess and mitigate supply-chain risk
Identify and assess risks across the Annex X categories, then act on them with a documented plan. Mitigation is expected to reach the field, including consultation with affected stakeholders.
Get third-party verification from a notified body
Chapter VII requires an external verification and periodic audit, not a self-declaration. The outputs of that process become part of the file you keep and disclose.
Report publicly and keep the file for ten years
The Regulation ends the cycle with disclosure and retention. Both the annual report and the archived audit trail need to draw from the same current record.
Anchor every material to supplier evidence
The traceability system is only as defensible as the records behind each Annex X material. A reviewer should be able to move from a material to its supplier, its origin, and the verification that supports it.
Watch the parallel US documentation demands
Companies with US exposure are already being asked for battery-material evidence outside the EU regime. The material lists differ, but the underlying work of tracing origin and collecting supplier attestations overlaps.
Keep the file review-ready, not just complete
A complete policy is not the same as an auditable one. Valent helps teams keep the due-diligence policy, supplier evidence, risk decisions, and reports connected so the annual report and the notified body's audit draw from one current record.
Build the due-diligence file before the audit window
Use these checks to keep the evidence trail current before a notified body, a downstream customer, or a market surveillance authority asks for it.
Run the net-turnover test against the EUR 40 million threshold, including group consolidation, and record whether Chapter VII applies.
Adopt an OECD-aligned due-diligence policy, communicate it to suppliers and the public, and assign top-management oversight.
Build the policy and risk-management measures into supplier contracts.
Stand up a chain-of-custody and traceability system that records supplier name and address, country of origin, the transaction chain from extraction, and the quantity of each Annex X material.
Collect notified-body verification reports covering suppliers, and CAHRA-level origin data where those reports are unavailable.
Assess and mitigate risk across the environmental, human-rights, labour, and community-life categories, and open a grievance and early-warning channel.
Engage a notified body to verify and periodically audit the policy, and keep the verification report, approval decision, and audit reports for ten years.
Publish the annual due-diligence report, including online, and name the notified body in the summary of verifications.
Track the US demands in parallel: UFLPA chain-of-custody to origin for lithium, and supplier certifications for the FEOC material-assistance rules.
