The EU central DPP registry is live: what economic operators need to know

On 20 July 2026, the European Commission switched on the central Digital Product Passport registry, together with a testing environment, user guidance and a helpdesk. Four days earlier it had adopted Implementing Regulation (EU) 2026/1778, the rulebook that governs how the registry operates. For the battery industry the consequence is direct: every battery passport required from 18 February 2027 must be declared in this registry before the battery is placed on the EU market. This article explains what the registry is, what it is not, and what economic operators should do with the roughly five months that remain.

What is the central DPP registry, and what is it not?

The registry is established under Article 13 of the Ecodesign for Sustainable Products Regulation (EU) 2024/1781, which required the Commission to have it running by 19 July 2026. It went live one day after that deadline. Its job is narrow: it is a central index of the products on the EU market that carry a digital passport, storing unique identifiers, a pointer to where each passport is hosted, and limited metadata such as customs commodity codes.

What it is not matters just as much. The registry is not a giant EU database holding the content of every passport. The passport data itself, the 90+ Annex XIII attributes in the battery case, stays decentralised: it lives in the systems of the manufacturer or its service provider and is reached through the QR code on the product. The registry answers the question "does a valid passport exist for this identifier, and where is it", not "what is in it".

Nor is registration a compliance certificate. The implementing regulation is explicit that the automated checks performed at registration verify technical conformity, not the substance of the data. A registered passport full of wrong carbon-footprint figures is still a non-compliant passport.

Which identifiers does the registry expect?

Registration revolves around a small set of identifiers, and the harmonised standards covering them are largely in place: six of the eight standards requested from the European standardisation bodies, covering identifiers, data carriers, interoperability and APIs, were already published at launch. In practice a registration involves:

• The unique product identifier. For batteries this is the per-unit battery identifier assigned under Article 77 of Regulation 2023/1542, the same one encoded in the QR code. Other product groups may register at model or batch level; battery passports are individual records, so registration happens at item level.
• The link to the hosted passport. The registry stores where the passport data can be reached, and checks at submission that the link resolves. The passport must also carry the operator and facility identifiers that tie the record to a verified company and production site.
• The commodity code. The customs classification of the product is validated at registration and later matched against the import declaration, which is how the registry plugs into border controls.
• The unique registration identifier. This one flows the other way: the registry issues it once the submission passes its checks. It is the reference that customs and market surveillance authorities use, and the Commission provides proof of registration as a secure electronic document that can be shown to business partners.

How does registration work in practice?

Before an operator can register anything, it must prove who it is. Implementing Regulation 2026/1778 requires identity verification under the eIDAS framework: a qualified electronic signature for sole traders, a qualified electronic seal for legal entities, issued by a qualified trust service provider. A completed verification remains valid for up to three years.

Once verified, two channels are open. A secure web interface serves low-volume cases, and an API serves automated, high-volume registration. A battery maker declaring passports per unit, potentially thousands of packs a week, will realistically need the API wired into its production or ERP flow rather than a person with a browser.

Each submission then passes automated checks: semantic conformity of the data, the correct granularity level, a valid commodity code, and a working link to the hosted passport. Pass, and the registration identifier comes back. Fail, and the passport is not registered, which from 18 February 2027 means the battery is not placeable on the EU market.

What changes for manufacturers and importers?

The obligation sits with the economic operator placing the product on the market. For an EU manufacturer that is the manufacturer itself; for a battery built outside the EU it is the importer. Non-EU cell makers cannot register on their EU customers' behalf and walk away: the importer carries the duty and the exposure.

Concretely, the registry adds a gate to the launch pipeline:

• No registration, no market. Registration must precede placing on the market, so it becomes a step in the release process, on the critical path alongside CE conformity.
• Customs gets a lookup. For imports, the declared commodity code and the registered passport can be cross-checked at the border. A missing or mismatched registration is now visible to customs, not only to a market surveillance inspector months later.
• Authorities get one door. Market surveillance authorities across all Member States use the registry to verify that passports exist for products on their market, and each Member State must appoint a national administrator for registry access by 18 February 2027.
• Hosting stays your problem. Because the registry stores none of the passport content, availability, security and continuity of the actual passport data remain the responsible operator's obligation, including keeping the passport reachable if a service provider changes or ceases activity.

For battery companies the volume is the real shift. Registering one model is a form; registering every pack placed on the market is an integration project.

How does the timing line up with 18 February 2027?

The sequencing is deliberately generous, but only for those who use it. The registry went live on 20 July 2026 and the implementing regulation entered into force on 6 August 2026. Batteries are the first product group through the gate: EV batteries, LMT batteries and industrial batteries above 2 kWh placed on the market from 18 February 2027 must have a registered passport, while the ESPR product groups such as textiles and steel follow on their own later timelines.

That makes the current window, from launch to February 2027, the preparation period, and the Commission has published a testing environment precisely for it. A realistic readiness sequence looks like this:

• Obtain the qualified seal now. eIDAS qualified seals come from trust service providers with their own onboarding lead times; this is the step companies underestimate.
• Fix the identifier scheme. Per-unit battery identifiers under Article 77 must be assigned consistently across production, the QR data carrier and the passport record.
• Decide the hosting model. In-house or through a passport service provider, with the continuity guarantees the regulation expects.
• Integrate and rehearse. Connect the registration API to production data and run real submissions in the testing environment before the first commercial batch depends on it.

Conclusion: a thin index that gates a whole market

The central registry is deliberately thin: it stores identifiers and pointers, not your data, and its checks are technical, not substantive. But from 18 February 2027 that thin index entry is what stands between a battery and the EU market, and for batteries it must exist per unit, issued through a verified identity and a working data link. The heavy work remains on the operator's side: a passport with correct Annex XIII content, hosted reliably, kept current through the battery's life.

Passoria's passport engine structures Annex XIII data per unit with the identifiers and hosted records a registration depends on, so declaring a passport becomes a byproduct of producing one. If 2027 readiness is on your roadmap, our pilot program is open to a limited number of manufacturers, resellers and recyclers.
