The EU battery passport is no longer just a far-off compliance idea. The European Commission rolled out the Digital Product Passport Registry and testing environment on July 20, 2026, in preparation for the February 18, 2027 deadline.

What’s the Scoop?

According to Regulation (EU) 2023/1542, every electric vehicle battery, light means of transport battery, and industrial battery over 2 kWh that enters the EU market will need an electronic battery passport starting February 18, 2027. The Commission has announced that the DPP Registry is now up and running and ready for testing.

But this battery regulation isn’t just about a simple product ID. Annex XIII goes deeper, requiring detailed information about battery composition for authorized users who have a legitimate interest. This includes specifics on the materials used in the cathode, anode, and electrolyte.

Why This Matters for PC Buyers

For companies sourcing propylene carbonate for battery-electrolyte formulations, the key concern is ensuring their documentation is up to standard. While the new rule doesn’t impose restrictions on PC itself, it also doesn’t mean that every PC purchase will need its own passport. However, battery manufacturers affected by the regulation will need reliable composition data throughout their supply chains.

This could elevate the importance of documentation quality on the supplier-qualification checklist. Procurement teams might need to verify what product identity, specifications, lot numbers, composition details, and supporting records their internal compliance teams or downstream customers will expect.

What Buyers Should Keep an Eye On

1  Internal data requirements. Battery manufacturers should identify which electrolyte material details need to be communicated from suppliers into their passport process.

2  Consistency in supplier documentation. Product specifications, Certificates of Analysis (COAs), Safety Data Sheets (SDSs), and lot records will be increasingly important as downstream data needs to be structured and traceable.

3  Guidance from the Commission on implementation. The registry is operational, but businesses should stay tuned for technical guidance and access-right rules as the February 2027 deadline draws near.

GreenChem Takeaway

For those purchasing battery-related PC, the practical journey ahead is all about ensuring compliance and documentation readiness. The real question isn’t whether propylene carbonate is “allowed,” but rather whether the sourcing file has all the necessary information that battery producers will need down the line. Buyers who take the time to clarify their documentation requirements before 2027 can save themselves from scrambling to qualify suppliers and clean up data at the last minute.
