The Real Stakes for Compliance Professionals With the EU Battery Regulation

Article Highlights:

• As of 2026, the EU Battery Regulation is firmly in its implementation phase. While it began to apply to in-scope organizations beginning in February 2024, the most substantive obligations are being phased in between 2025 and 2028, with further thresholds extending into the 2030s.
• The EU Battery Regulation imposes requirements on manufacturers for certain types of batteries, and spans everything from carbon accounting to production obligations to material restrictions. 
• The regulation also introduces performance and durability requirements for rechargeable industrial and EV batteries. These requirements are intended to ensure longer battery life spans and improved resource efficiency—obligations that have a direct impact on the product design and validation processes.
• Finally, the regulation imposes supply chain due diligence requirements for certain economic operators placing batteries on the EU market. Though these obligations have been amended and their implementation postponed, the European Commission is expected to publish detailed due diligence guidelines by July 2026.

The EU Battery Regulation refers to the European Union’s Regulation 2023/1542, which entered into force on August 17, 2023 and started applying to in-scope businesses starting on February 18, 2024. It replaced Directive 2006/66/EC, which was fully repealed in August 2025.

Unlike the previous directive, which required national transposition and resulted in fragmented implementation across the EU’s member states, the EU Battery Regulation is directly applicable across the European Union, creating a harmonized legal framework.

The regulation applies to five battery categories:

• Portable batteries
• Starting, lighting, and ignition (SLI) batteries
• Light means of transport (LMT) batteries
• Industrial batteries
• Electric vehicle (EV) batteries

The defining feature of the EU’s new battery regulation is lifecycle regulation. It governs batteries from raw material sourcing and manufacturing to market implementation and use-phase performance to repurposing and recycling.

For compliance professionals, this marks a structural expansion of scope. Battery regulation in the EU is no longer limited to waste and collection obligations. It now integrates sustainability metrics, carbon accounting, supply chain due diligence, and digital traceability directly into market access requirements.

The EU Battery Regulation aligns with broader EU policy frameworks, including the Circular Economy Action Plan and climate neutrality objectives, while also addressing strategic raw material security.

Why the EU Battery Regulation Matters in 2026

As of 2026, the EU Battery Regulation is firmly in its implementation phase. While it began to apply to in-scope organizations beginning in February 2024, the most substantive obligations are being phased in between 2025 and 2028, with further thresholds extending into the 2030s.

The regulation is a cornerstone of the EU’s industrial and climate strategy. Batteries underpin vehicle electrification, renewable energy storage, and broader decarbonization pathways. Because of its essential role in all these avenues to reducing greenhouse gas emissions, the EU is seeking to ensure that battery value chains are transparent, responsible, and resilient.

For compliance professionals, this means that the stakes are significant and multifaceted. 

• Market access is directly tied to compliance. Noncompliant batteries cannot be placed on the EU market.
• Supply chain transparency requirements—including carbon footprint declarations, recycled content mandates, and forthcoming battery passport obligations—expose data gaps, weak supplier governance, and traceability limitations.
• Battery compliance is no longer a narrow product-level issue. It is now a cross-functional governance challenge spanning engineering, procurement, sustainability, and regulatory compliance.

Because of its essential role in all these avenues to reducing greenhouse gas emissions, the EU is seeking to ensure that battery value chains are transparent, responsible, and resilient.

Key Compliance Requirements

The EU Battery Regulation imposes requirements on manufacturers for certain types of batteries, and spans everything from carbon accounting to production obligations to material restrictions. 

Sustainability and Carbon Footprint Requirements

Starting in 2025, carbon footprint declaration requirements began to apply to:

• Electric vehicle (EV) batteries
• Rechargeable industrial batteries with a capacity above 2 kWh

These obligations are being operationalized in phases through 2026, as implementing acts define the methodology and verification framework.

Manufacturers are required to calculate lifecycle greenhouse gas emissions and obtain third-party verification. Future acts will introduce carbon footprint performance classes and maximum lifecycle thresholds.

Performance and Durability

The regulation also introduces performance and durability requirements for rechargeable industrial and EV batteries. These requirements are intended to ensure longer battery life spans and improved resource efficiency—obligations that have a direct impact on the product design and validation processes.

Removability and Replaceability

Article 11 requirements enter into force beginning on February 18, 2027. These requirements stipulate that portable batteries in appliances must be readily removable and replaceable by end users or independent professionals, subject to defined exemptions.

These forthcoming obligations will require compliance professionals to work with engineering to ensure that their products’ design adheres to these new requirements.

Hazardous Substances

The regulation maintains and updates restrictions on hazardous substances, including mercury, cadmium, and lead. These provisions largely carry forward existing restrictions under the previous directive, with updates, exemptions, and review clauses incorporated.

These requirements operate alongside obligations under the REACH and RoHS frameworks, reinforcing chemical compliance across the battery lifecycle.

Recycled Content and Material Transparency

Recycled content declaration requirements began to apply in August 2028 for:

• EV batteries
• Industrial batteries
• SLI batteries

These content declarations must cover cobalt, lithium, nickel, and lead. Minimum recycled content thresholds apply beginning in 2031, with increased levels from 2036.

This distinction is critical. Recycled content obligations do not begin in 2025. The earlier obligations relate to carbon footprint reporting, not material recovery.

Due Diligence Obligations for Compliance Professionals

One of the most transformative elements of the EU Battery Regulation is mandatory supply chain due diligence for certain economic operators placing batteries on the EU market.

Updated Legal Timeline

Due diligence obligations were formally amended by Regulation (EU) 2025/1561, which postponed their application until August 2027.

In parallel, the European Commission is expected to publish detailed due diligence guidelines by July 2026, which will define practical implementation requirements.

One of the most transformative elements of the EU Battery Regulation is mandatory supply chain due diligence for certain economic operators placing batteries on the EU market.

Scope of Due Diligence

These due diligence obligations apply primarily to economic operators placing on the market:

• EV batteries
• Industrial batteries
• LMT batteries

Companies must establish due diligence policies addressing environmental and social risks associated with raw materials—including cobalt, lithium, nickel, and natural graphite.

The due diligence framework requires:

• Risk identification and assessment
• Prevention and mitigation measures
• Independent third-party verification
• Public reporting

Operationally, this extends compliance beyond Tier 1 suppliers, into manufacturing sub-tiers. To comply effectively, manufacturers may need to gain visibility and traceability further up their value chains than ever before. 

Ongoing policy discussions may further refine scope and proportionality requirements, particularly for smaller operators. The core framework, however, has been firmly established.

Conformity, Labeling, and Battery Passport Rules

The EU Battery Regulation includes requirements for CE markings and digital battery passports. 

CE Marking and Conformity Assessment

Batteries placed on the EU market must bear the CE marking. Under the regulation, a CE marking reflects compliance with an expanded set of requirements, including safety, performance, durability, and certain sustainability criteria (where applicable).

Technical documentation requirements expand accordingly and will increasingly include:

• Carbon footprint data (where applicable)
• Recycled content declarations (from 2028)
• Due diligence documentation (from 2027)

Battery Passport

Beginning on February 18, 2027, a digital battery passport becomes mandatory for:

• EV batteries
• Rechargeable industrial batteries above 2 kWh
• LMT batteries

The passport must be accessible via a QR code and contain structured data on carbon footprint, material composition, performance, durability, and end-of-life handling. When digital battery passport requirements enter into force, it will represent a fundamental shift toward digital compliance infrastructure and real-time data accessibility.

Who Is Affected by the EU Battery Regulation?

The regulation applies across the value chain, including a myriad of different stakeholders:

• Manufacturers
• Importers
• Distributors
• Authorized representatives
• Fulfilment service providers
• Recyclers and waste operators

Manufacturers retain primary responsibility for conformity. Importers must verify compliance before placing products on the market, while distributors must ensure that required markings and documentation are present.

Downstream OEMs integrating batteries into their products must also ensure compliance with removability, performance, and labeling requirements.

Compliance Deadlines and Phased Implementation

The Regulation follows a structured timeline that is multifaceted but relatively easy to understand and follow: 

• August 17, 2023: The EU Battery Regulation entered into force.
• February 18, 2024: General application begins.
• August 18, 2025: The EU fully repeals Directive 2006/66/EC.
• 2025–2026: Over a two-year span, the EU is gradually phasing in carbon footprint requirements (EV and >2 kWh industrial batteries).
• February 18, 2027: Removability requirements and battery passport obligations apply.
• August 18, 2027: Due diligence obligations apply (as amended).
• August 18, 2028: Recycled content declarations apply.
• 2031-2036: Minimum recycled content thresholds undergo phased implementation.

Penalties and Risks of Noncompliance

Member states are required to establish effective, proportionate, and dissuasive penalties for noncompliance. These may include market withdrawal, administrative fines, corrective actions, and increased regulatory scrutiny.

Because CE marking constitutes a formal declaration of conformity, unsupported or inaccurate claims can create additional liability exposure.

Managing New Regulations With a Compliance Tool 

The EU Battery Regulation’s framework will continue to evolve through subsequent acts and implementations, particularly in areas such as carbon footprint methodology, recycled content calculation, and due diligence verification.

Further, enforcement is expected to intensify as digital infrastructure—and in particular the battery passport—becomes operational, enabling greater transparency and cross-border oversight.
