Digital product passport architecture for ecommerce

Digital Product Passport Architecture for Ecommerce

Regulatory status: October 18, 2026. Technical guidance, standards and product-specific rules continue to develop. Confirm requirements for each product group before implementation.

Digital Product Passports connect physical products with structured data about origin, materials, compliance, repair and lifecycle. Regulation (EU) 2024/1781, known as the Ecodesign for Sustainable Products Regulation or ESPR, creates the horizontal DPP framework. Product-specific delegated acts determine when that framework applies and what each passport must contain. (eur-lex.europa.eu)

Battery passports follow a separate but connected regime. Under Article 77 of Regulation (EU) 2023/1542, passports become mandatory on February 18, 2027 for each light means of transport battery, electric-vehicle battery and industrial battery above 2 kWh. The rule covers batteries placed on the EU market or put into service. These concepts broadly concern first commercial availability and first intended use in the EU. (eur-lex.europa.eu)

How DPP architecture works

No single architecture is mandatory. A practical digital product passport architecture can use seven layers:

1. Source and evidence systems: ERP, PIM, PLM and supplier portals provide verified product records and supporting documents.
2. Identifier management: Services assign and maintain product, operator and facility identifiers at the required model, batch or item level.
3. DPP data layer: A canonical model maps source data to applicable product-group rules and technical standards. It must support schema changes.
4. Passport service: This service validates, versions and publishes passports. It should also manage corrections, withdrawal states and evidence provenance.
5. Identity and access: Authentication and authorization separate public, restricted and authority-only data. Designs should minimize personal data and protect trade secrets.
6. Registry integration: An adapter registers required identifiers and metadata with the EU DPP Registry. It stores the returned registration identifier and generated proof of registration.
7. Resolution and presentation: A durable URL resolves the product's data carrier to an accessible passport page and machine-readable interface.

The EU DPP Registry became operational on July 20, 2026. Registration is available through a user interface or API. The registry stores identifiers, registration data and high-level metadata. Product-specific legislation may require additional information. A registration response is not proof that the product complies with every applicable rule. (single-market-economy.ec.europa.eu)

Detailed passport data usually remains under the economic operator's responsibility and may be hosted by an authorized DPP service provider. Architecture should still isolate the registry adapter because guidance, schemas and category rules can change. (single-market-economy.ec.europa.eu)

What good DPP ecommerce integration looks like

Consider a merchant selling equipment with a regulated industrial battery. First determine who places the battery on the market or puts it into service. That economic operator is responsible for the battery passport. A distributor may only display an existing passport. An importer or private-label seller may assume broader duties depending on its role and branding. A service provider can operate the platform but does not automatically inherit regulatory responsibility. (eur-lex.europa.eu)

The storefront should retrieve public passport data rather than become its source of truth. Product pages should support:

• the correct passport for each variant or serialised item
• multiple passports for bundles or embedded regulated components
• visible access before purchase where applicable
• localized and accessible passport pages
• cache invalidation after corrections or recalls
• clear fallback messaging during API or hosting outages
• validation of broken links and invalid data carriers
• consistent passport links in marketplace feeds

Under ESPR, dealers must make required passports easily accessible when the applicable delegated act requires one. The responsible economic operator must provide dealers and marketplace providers with the data carrier, identifier or link needed for remote sales. Marketplace providers also have separate cooperation duties toward surveillance authorities. (eur-lex.europa.eu)

For regulated batteries, a QR code must provide access to the battery passport. ESPR uses the broader term "data carrier," so QR codes should not be treated as universal for every future product group. (eur-lex.europa.eu)

Prepare before your category becomes mandatory

Start with a data audit. Identify missing supplier evidence, conflicting identifiers and unclear ownership. Then define versioning, audit logs, access rules, monitoring and service-level targets. Add plans for ownership transfer, provider migration, backups and operator insolvency.

Retention must follow the applicable legislation. Battery passports must remain available if the responsible operator ceases trading and end after recycling. Repurposing or remanufacturing can transfer responsibility and require a new passport linked to the original record. (eur-lex.europa.eu)

Stable ecommerce data contracts and careful avoidance of data-model mistakes reduce migration risk. Businesses with fragmented systems may also benefit from an architecture audit.
