The European Union's Digital Product Passport framework is reshaping compliance obligations across the automotive supply chain, imposing new data collection and labeling requirements on manufacturers, tier suppliers, and logistics partners as phased mandates approach.
Anchored in Regulation (EU) 2024/1781, the Ecodesign for Sustainable Products Regulation (ESPR), DPPs are set to become central to EU product compliance. A DPP functions as a digital data container designed to enhance transparency, traceability, and circularity by providing standardized, product-specific sustainability and lifecycle data. For the automotive sector, the mandate carries particular urgency: the Battery Passport under Regulation (EU) 2023/1542 becomes mandatory from February 18, 2027, covering all industrial batteries exceeding 2 kWh and all electric vehicle batteries placed on the EU market.
Background
The Ecodesign Regulation came into force in July 2024, paving the way for product-specific standards during 2025 and 2026. The 2025-2030 Work Plan, adopted on April 15, 2025 by the European Commission, lists the priority products for which ecodesign requirements-and therefore DPP-based information obligations-will be developed progressively between 2026 and 2030. From 2026, the ESPR begins with iron and steel; in 2027, aluminium and tyres follow-both material categories with direct implications for automotive component supply chains.
By July 19, 2026, the European Commission is required to establish a central DPP registry to support enforcement and transparency, according to Article 13 of the ESPR. The Commission also plans a publicly accessible portal allowing users to search and compare DPP data, and will define requirements and certification schemes for third-party DPP service providers under delegated acts-certified software or platform companies that will host product data and ensure compliance with access rules and cybersecurity obligations.
Automotive manufacturers including General Motors, Ford, and Tesla producing vehicles for European markets will need complete battery passport data. The DPP applies beyond EU-based companies: all products in the relevant categories entering the EU market, regardless of country of manufacture, must carry a corresponding DPP.
Details
For the automotive supply chain, the data architecture underpinning DPP-compliant labels is technically demanding. Access to the DPP must be provided via QR code, NFC chip, or RFID tag; manufacturer, importer, and operator details must be embedded; and the DPP must comply with ISO/IEC 15459:2015, which outlines standards for the electronic capture of unique item identifiers such as serial numbers to ensure cross-system recognition. DPP systems must also support APIs, structured data schemas, and machine-readable formats such as JSON-LD and EPCIS to enable cross-platform data exchange, allowing suppliers, manufacturers, regulators, and recyclers to securely access relevant data without duplicating systems.
Data requirements vary by product group but are expected to include material composition, substances of concern, environmental performance indicators, durability, and end-of-life information. For EV batteries, the requirements already encompass over 100 data attributes, including material composition with geographic origin for conflict minerals, carbon footprint broken down by lifecycle stage, recycled content percentages, and state-of-health performance metrics.
The compliance burden falls unevenly across the value chain. DPP success depends fundamentally on supplier data quality and cooperation, yet typical automotive or electronics manufacturers source from 500 to 5,000 direct suppliers across 30 to 50 countries. For the DPP to function across sectors, information must follow common standards and be correctly interpreted by any system. If different sectors develop passports with divergent requirements, suppliers serving multiple industries could face significant compliance overhead managing multiple formats. Data sovereignty tensions add further complexity: EU GDPR mandates European data localization, while China's Cybersecurity Law requires Chinese storage for certain data categories, forcing manufacturers operating in both markets into difficult compromises.
Packaging design is also directly affected. The DPP data carrier must be physically present on the product, its packaging, or accompanying documentation. The regulation enforces tiered access controls: public data must be available in all 24 EU languages, while sensitive commercial data is restricted to authorized users, including repairers and regulators. Contract language between OEMs and tier suppliers will need to reflect these layered data-access obligations and assign clear responsibility for data accuracy and updates throughout a component's lifecycle.
Outlook
Lessons from the Battery Passport implementation, mandatory from February 2027, are expected to inform the rollout of DPPs for other automotive component categories. Industry experts widely estimate that a realistic compliance timeline for a typical manufacturer spans 12 to 18 months. The Automotive Industry Action Group is actively exploring supply chain transparency frameworks ahead of formal mandates. Because DPP requirements will be defined through delegated acts for specific product groups, companies must continuously track regulatory developments to determine when their products become subject to formal obligations and what precise data fields apply.
