The European Union's Digital Product Passport framework is reshaping sourcing and traceability obligations across the automotive sector. A mandatory Battery Passport for electric vehicle and industrial batteries takes effect 18 February 2027, imposing new data and verification demands on OEMs, tier suppliers, and recyclers.
Background
The regulatory basis is Regulation (EU) 2023/1542, the EU Battery Regulation, which entered application in February 2024 and fully replaced the previous Battery Directive (2006/66/EC) on 18 August 2025. The broader Digital Product Passport concept is anchored in Regulation (EU) 2024/1781, the Ecodesign for Sustainable Products Regulation (ESPR), which positions the Battery Passport as the first mandatory DPP-a pilot for requirements that will later extend to other product categories including tyres, electronic control units, and catalytic converters.
The Battery Passport is an electronic record linked to a unique product identifier, accessible via a QR code on the physical unit, that consolidates verified data on composition, performance, carbon footprint, and end-of-life processing. According to law firm Hogan Lovells, standardization for core Battery Passport data was released in early 2025, establishing the schema suppliers and OEMs must follow.
Carbon footprint disclosure obligations have already begun phasing in. From 18 February 2025, manufacturers were required to calculate and declare the carbon footprint for each battery model and manufacturing plant, covering all relevant lifecycle stages from raw material extraction through battery assembly, distribution, and end-of-life processing. The declaration must be third-party verified and publicly accessible online, though the data need not reside within the Battery Passport itself until 2027.
Compliance Scope and Data Requirements
The passport mandate applies to all EV, light means of transport (LMT), and industrial batteries with a capacity exceeding 2 kWh placed on the EU market, regardless of their country of manufacture. This geographic neutrality means battery module suppliers and pack assemblers outside the EU-including those in Asia and North America supplying European automakers-face the same obligations as domestic producers.
The compliance burden is explicitly multi-tier. According to Informatica's implementation analysis, 60-80% of the data required for a Battery Passport comes from suppliers across multiple tiers, with an automotive OEM's passport requiring inputs from battery cell manufacturers at Tier 1 down to raw material miners at Tier 3 and recyclers. Access to passport data will be tiered: some fields are restricted to notified bodies, market surveillance authorities, and the European Commission, while other records-including dismantling procedures, detailed chemical composition, and safety data-will be accessible to repairers, remanufacturers, and recyclers with a demonstrated legitimate interest.
Due diligence obligations covering raw materials such as cobalt, natural graphite, lithium, and nickel were postponed from August 2025 to 18 August 2027 through Regulation (EU) 2025/1561, giving supply chain teams additional time to map sourcing networks and build internal verification procedures. Separately, minimum recycled content thresholds - including 12% cobalt, 4% lithium, and 4% nickel from non-virgin sources - are set to apply from 2030.
For cross-border sourcing, the DPP introduces direct contractual implications. Automotive OEMs sourcing battery modules from Tier 1 suppliers must verify that those suppliers' data-and their upstream inputs-conform to the standardised schema or risk being unable to place compliant products on the EU market. According to analysts at Ramboll, compliance will require new data collection systems, supplier coordination, and in some cases redesigning production processes.
Outlook
By mid-2026, the European Commission is expected to deploy a central EU DPP registry, and a publicly accessible portal allowing users to search and compare DPP data is also planned. Eight harmonised standards covering DPP data and interoperability are expected around the same time. Beyond batteries, tyre DPP delegated acts are anticipated between 2027 and 2028, with vehicle component requirements covering electronic control units and safety-critical parts expected by 2028-2029, and vehicle-level DPP requirements likely by 2029-2030. Industry analysts estimate a 12-18 month timeline for companies to establish the necessary data infrastructure once a delegated act is formally adopted, meaning automotive suppliers with exposure to multiple component categories face concurrent compliance cycles with limited margin for delay.
