Why DPP Data Verification Matters

Data verification is the process of confirming that the information in a Digital Product Passport is accurate, complete, and based on reliable evidence. Without verification, DPPs risk becoming repositories of unsubstantiated claims, undermining trust in the system and defeating its regulatory purpose.

The ESPR establishes a framework where DPP data must be verifiable, meaning market surveillance authorities and other stakeholders can check that declarations are supported by evidence.

Verification Methods

DPP data can be verified through multiple approaches:

• Self-declaration with supporting documentation: manufacturer maintains evidence files
• Third-party testing: independent laboratories verify performance claims
• Notified body assessment: conformity assessment for regulated products
• Automated validation: system checks for data consistency and completeness
• Peer verification: supply chain partners confirm data they have contributed

The appropriate verification method depends on the data type, the product category, and the regulatory requirements. Critical claims like safety performance typically require third-party verification.

Market Surveillance

Market surveillance authorities across EU Member States have the power to check DPP data accuracy. They can request supporting documentation, commission independent testing, and take enforcement action if passport data is found to be inaccurate or misleading.

Maintaining comprehensive documentation that supports every DPP data point is essential for responding to market surveillance inquiries efficiently.

Building Verification into Your Process

Establish data verification procedures at each stage of DPP creation. Validate data as it enters the system, maintain audit trails, and conduct periodic reviews of published passport data against current product specifications.

MyProductPassport includes built-in data validation and audit trail features, helping ensure your DPP data is accurate and verifiable at all times.
