Readiness guide

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.

Operational guide, not legal advice

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.

Why this matters

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.

Map your battery due-diligence evidence workflow

Where readiness usually breaks down

Scope is assumed instead of tested. A company treats itself as exempt without running the net-turnover check against the EUR 40 million threshold, including group consolidation.
A due-diligence policy exists on paper but was never communicated to suppliers or written into supplier contracts.
Origin data stops at the immediate supplier, with no chain of custody back to country of origin or, where needed, the mine.
Verification is planned as an internal sign-off, when Chapter VII requires a notified body to verify and periodically audit the policy.

EU Battery Regulation due-diligence map

Regulation

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.

Materials in scope

Cobalt, natural graphite, lithium, and nickel, plus the chemical compounds based on them that are needed to make battery active materials (Annex X).

Who is obligated

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.

When it applies

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.

Verification

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.

Not conflict minerals

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

18 February 2027

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.

18 August 2027

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.

01

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.

Run the net-turnover test against the EUR 40 million threshold, including group consolidationRemember the exemption covers only due diligence, not passports, CE conformity, or labellingConfirm which battery categories you place on the market or put into serviceNote that an authorised representative cannot take on these obligations for you
02

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.

Align the policy with the OECD Due Diligence Guidance and the instruments named in Annex XCommunicate it clearly to suppliers and the publicAssign top-management oversight of the policyBuild the policy and risk-management measures into supplier contracts
03

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.

Record trade name, supplier name and address for each materialCapture country of origin and the transaction chain from extraction to your immediate supplierRecord the quantity of each Annex X material in the battery, by percentage or weightGather notified-body verification reports covering suppliers, and CAHRA-level data such as mine of origin and trading or processing locations where those reports are unavailable
04

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.

Assess environment, climate, and human-health risksAssess human-rights and labour-rights risks, including child labour and forced labourAssess risks to community life, including that of indigenous peoplesReport findings to top management, run a risk-management plan, and open a grievance and early-warning channel
05

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.

Engage a notified body to verify and periodically audit the policyObtain the verification report and approval decisionTreat internal audits or self-assessment as insufficient on their ownWatch for any industry scheme the Commission recognises as equivalent; none is recognised yet
06

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.

Publish an annual report, including on the internet, covering the policy, significant adverse impacts and how they were addressed, and a summary of verifications naming the notified bodyMake relevant information available to immediate downstream purchasers, with regard to business confidentialityKeep the verification report, approval decision, and audit reports for ten years after the last battery under the policy was placed on the marketDisclose your conclusions when claiming Annex X materials come from recycled sources

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.

Supplier name and address for each material
Country of origin and the transaction chain from extraction to your immediate supplier
Quantity of each Annex X material in the battery, by percentage or weight
Notified-body verification reports covering suppliers, which those suppliers must make available downstream

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.

UFLPA lists lithium as a high-priority enforcement sector since August 2025
Importers with China exposure must produce chain-of-custody documentation back to raw-material origin for CBP
IRS Notice 2026-15 lets taxpayers rely on supplier certifications about prohibited-foreign-entity content and origin
Battery and storage makers are collecting cost and origin documentation from suppliers to protect 45X, 48E, and 45Y credits

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.

Policy communicated to suppliers and reflected in contracts
Grievance, early-warning, and remediation channel with a decision trail
Ten-year retention of the verification report, approval decision, and audit reports
Annual public report that names the notified body and states how significant adverse impacts were addressed
Checklist

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.

01

Run the net-turnover test against the EUR 40 million threshold, including group consolidation, and record whether Chapter VII applies.

02

Adopt an OECD-aligned due-diligence policy, communicate it to suppliers and the public, and assign top-management oversight.

03

Build the policy and risk-management measures into supplier contracts.

04

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.

05

Collect notified-body verification reports covering suppliers, and CAHRA-level origin data where those reports are unavailable.

06

Assess and mitigate risk across the environmental, human-rights, labour, and community-life categories, and open a grievance and early-warning channel.

07

Engage a notified body to verify and periodically audit the policy, and keep the verification report, approval decision, and audit reports for ten years.

08

Publish the annual due-diligence report, including online, and name the notified body in the summary of verifications.

09

Track the US demands in parallel: UFLPA chain-of-custody to origin for lithium, and supplier certifications for the FEOC material-assistance rules.
