Digital Product Passport: what EU regulation requires by 2027, and how to prepare in 2026

The Digital Product Passport (DPP) is the EU's flagship supply-chain transparency mechanism, mandatory for batteries starting 2027 under the EU Battery Regulation, and rolling out to electronics, textiles, and other categories under the Ecodesign for Sustainable Products Regulation (ESPR) through 2030. Lean SupplAI was built with DPP-style data structures in mind, because the underlying procurement transparency is the same problem regardless of regulatory framing.

For hardware companies selling into the EU, the DPP is not optional. By 2027, every battery placed on the EU market must carry a unique digital passport accessible via QR code or NFC, containing supply-chain origin, carbon footprint, recycled content percentage, and end-of-life recycling instructions.

What the DPP actually contains

The DPP is a data structure with mandatory and optional fields. Mandatory fields for batteries include manufacturer identifier, battery model, manufacturing date and location, chemistry, capacity, weight, hazardous substances, recycled content percentage, carbon footprint, due-diligence audits, and end-of-life information. The data must persist for the product lifetime and remain accessible after end-of-life for recycling and material recovery.

Where the data comes from

This is the procurement problem inside the regulation. Most of the DPP data lives with suppliers: cell manufacturers, cathode and anode material producers, mineral processors. Procurement teams need to pull this data through the supply chain, validate it, and aggregate it into the passport. Programs that wait for the regulation to land typically discover during audit that their suppliers cannot produce the underlying data, which means the passport itself fails compliance.

How to prepare in 2026

The work to get DPP-ready is supplier-data work. Programs that pass DPP audits cleanly do five things in 2026:

• Map the full supply chain to Tier-3, with verified provenance at every layer.
• Collect carbon footprint data per supplier in ISO 14064-aligned format.
• Track recycled content percentage at each material input.
• Maintain hazardous substance attestations under REACH and RoHS.
• Capture due-diligence audit history for high-risk minerals.

How Lean SupplAI tracks DPP-relevant data

Lean SupplAI maintains DPP-aligned supplier attributes as part of the standard supplier graph: provenance, carbon footprint, recycled content, hazardous substance status, due-diligence audits, and end-of-life recyclability. For procurement teams preparing for DPP rollout, Lean SupplAI compresses the data-collection cycle from a one-time scramble to a continuous workflow, with the passport-ready data available at sourcing time rather than at audit time.
