Digital Product Passports: The Technology Behind Product Transparency

The Big Question

What happens when a regulator, a recycler, or a consumer scans a product and needs to know what it is made of, where it came from, and how to dispose of it and that information does not exist in any reliable form? When a manufacturer cannot prove the recycled content of a component because the data was never captured? When a product reaches end-of-life and no one knows what materials it contains?

Digital Product Passports exist to close this gap. They are a structured, digital record that follows a product through its entire lifecycle, accessible via a data carrier such as a QR code .

What a Digital Product Passport Actually Is

A DPP is not a label. It is a data record linked to a physical product, part of a wider system for creating, managing, sharing, and accessing product information .

Depending on the product and applicable requirements, a DPP can include :

• Product identity and origin

• Materials and components

• Environmental characteristics

• Repair and maintenance information

• Safety and compliance information

• Instructions for reuse, recycling, or disposal

• Information about actors and events in the supply chain

The connection between the physical product and its digital record is made through a data carrier typically a QR code, barcode, or RFID tag .

The Regulatory Driver: ESPR and the EU Timeline

The DPP is introduced under the EU's Ecodesign for Sustainable Products Regulation (ESPR), which entered into force in July 2024 . The regulation establishes the framework, but the detailed requirements are defined per product group through delegated acts .

The Phased Timeline

Each delegated act must give businesses at least 18 months before compliance becomes mandatory .

Who Is Responsible

The primary responsibility for the DPP's creation and accuracy rests with the economic operators placing the product on the EU market  whether manufactured domestically or imported . This includes manufacturers, importers, authorized representatives, distributors, dealers, and fulfilment service providers .

Responsibilities include :

• Data compilation  providing product data digitally in accordance with the required data structure

• Registration  registering the DPP in the EU DPP Registry

• Lifecycle management  ensuring information remains accurate throughout the product's lifecycle

The Technical Architecture

The Eight Standards

In June 2026, the first six harmonized standards for the DPP system were published . Two more remain in draft.

Following these standards provides a presumption of conformity with the corresponding requirements of Articles 10 and 11 of the ESPR .

Decentralized Data Storage

The DPP system is deliberately decentralized. DPPs and product-specific data are hosted by the responsible economic operators or delegated to DPP service providers . The European Commission operates only a central registry that stores high-level metadata about the DPPs and products .

The critical implication: Organizations cannot rely on the EU to host their product data. They must build or procure the infrastructure to store, serve, and maintain DPP data themselves.

The Registry and Semantic Repository

The DPP registry became operational in July 2026, alongside a testing environment and a user guide for economic operators covering enrollment, identity verification, and passport registration .

A key component is the semantic repository  a collection of data models and semantic definitions that ensure common understanding across all users, including cross-lingual interpretation . This is what makes semantic interoperability possible: two systems can exchange DPP data and understand it the same way.

Data Carriers

The data carrier for each product group will be specified in its delegated act . QR codes and NFC chips are both under consideration, with the choice depending on the product's nature .

GS1 standards provide a foundation. GS1 Digital Link connects QR codes to structured product data, and GTINs provide unique product identification .

The Technology Stack

Building a DPP system requires several components working together.

Asset Administration Shell (AAS)

The AAS is a standardized digital representation of an asset, providing a common structure for exchanging information across systems . Fraunhofer ISST's DS4DPP project combines AAS with Data Spaces as the standard infrastructure for managing DPP data .

Data Spaces

Data Spaces provide the infrastructure for secure control of access, use, storage, and deletion of DPP data . They address a key challenge: not all DPP information should be public. Access rights need to vary by stakeholder  a recycler needs different information than a consumer or a regulator .

Blockchain for Traceability

Blockchain is being explored for its traceability, transparency, and immutability properties . A blockchain-based DPP can capture events and transformations across the product lifecycle, with a combination of on-chain and off-chain storage .

However, interoperability gaps remain. Research identifies incompatible data formats across platforms, lack of standardized governance for data updates, and absence of universal certification standards as key barriers .

AI for Data Quality

AI is not merely an efficiency tool for DPP  it is a critical strategic capability. AI is essential for managing data quality at scale, enhancing security, and transforming the DPP from a compliance burden into a value-creating asset through predictive analytics and personalized consumer engagement .

What Organizations Need to Build

1. Data Foundation

GS1 UK's guidance is direct: getting your data in order is absolutely critical. You cannot build a DPP without knowing what is in your products, how they are made, and where they have been .

The first steps :

• Audit your data  map what you have, where it lives, and what formats it is in

• Identify what is missing and what needs updating

• Adopt GS1 identifiers ensure every product has a unique GTIN

2. Technical Infrastructure

Organizations need infrastructure capable of hosting and maintaining DPP data . This includes:

• Storage for DPP data

• APIs for lifecycle management and searchability

• Data carriers and the systems to generate and manage them

• Access control and authentication mechanisms

• Integration with supply chain partners

3. Supply Chain Engagement

The practical challenge for many organizations will be data collection and verification from supply chains . Product information often needs to be sourced from multiple suppliers across different jurisdictions.

Supplier engagement is a critical component of successful implementation .

4. Lifecycle Management

DPP information must remain accurate throughout the product's lifecycle . This requires:

• Procedures for updating information

• Mechanisms for verifying accuracy

• Backup arrangements to ensure availability even if the original operator ceases operations

The Business Case Beyond Compliance

While compliance is the driver, the DPP creates additional value.

For supply chain management: Improved transparency and traceability can support better performance, strengthen market position, and unlock new opportunities in the circular economy .

For consumer trust: Transparency about product lifecycle is a key pillar of building trust and driving uptake of the circular economy .

For data quality: The discipline of building a DPP improves product data overall, which benefits many downstream systems.

For circular business models: The DPP enables repair, reuse, remanufacturing, and recycling by making the information needed for those activities accessible .

Implementation Roadmap

Phase 1: Assess (Weeks 1-4)

1. Determine if your products are in scope. Check the delegated act timeline for your product group.

2. Audit your data. Map what product data you have, where it lives, and what is missing .

3. Identify data gaps for the information a DPP will require.

4. Review supplier data availability and identify engagement needs .

Phase 2: Build (Weeks 5-12)

1. Adopt GS1 identifiers and implement GS1 Digital Link .

2. Build or procure DPP infrastructure  storage, APIs, access control.

3. Establish data collection processes with suppliers.

4. Design the data carrier strategy for your product group.

Phase 3: Operate (Weeks 13-16+)

1. Register DPPs in the EU registry when required .

2. Implement lifecycle management  procedures to keep data accurate.

3. Establish backup arrangements for data availability .

4. Monitor regulatory developments as delegated acts are published.
