# EU DPP supplier data validation workflow

A grounded workflow for checking supplier data before it is used in an EU Digital Product Passport, covering product linkage, evidence, owners, access class, and approval records.

*DPP* *Supplier data* *EU*

## EU Digital Product Passport Supplier Data Validation Workflow

A supplier intake and validation workflow for EU Digital Product Passport data before it is published, updated, or used for product compliance evidence.

Use it to check source owner, product link, evidence quality, access class, and approval records.

Supplier data used in an EU Digital Product Passport should be checked before it enters a passport record. ESPR requires DPP data to be connected to a persistent unique product identifier, refer to the product model, batch, or item specified in the relevant delegated act, and respect access rights for different actors. This workflow turns those requirements into validation gates for supplier evidence.

## Supplier intake gates before DPP data is accepted

Start the workflow when a supplier provides a new data field, a changed value, a certificate or declaration, a calculation input, a facility or operator identifier, or evidence for a product model, batch, or item that may appear in the Digital Product Passport.

Do not accept a supplier submission as passport-ready until it has a named source owner, a product link, and a stated access class. The economic operator placing the product on the EU market remains responsible for making the DPP available, so supplier intake should feed a controlled product record rather than an unmanaged inbox.

- Source owner gate: record the supplier legal entity, submitting contact, facility or operator identifier when relevant, and the internal owner who can ask for corrections.
- Product link gate: tie the submission to the product model, batch, or item level used by the passport, plus the product identifier or SKU mapping used internally.
- Evidence gate: require the supporting document, test report, declaration, calculation file, bill-of-materials extract, or system export that supports the value.
- Scope gate: label whether the data is required by the relevant delegated act, allowed under other Union law, or voluntary supporting information.
- Access gate: classify the field as public, restricted to named actors, authority-facing, or not suitable for the DPP because it contains unsupported confidential or personal data.

- [Regulation (EU) 2024/1781 (ESPR)](https://eur-lex.europa.eu/eli/reg/2024/1781/oj/eng?ref=sorena.io) - Article 10 requires a DPP to connect through a data carrier to a persistent unique product identifier and to regulate access according to access rights set in delegated acts.
- [CEN-CENELEC CWA 18186:2025 DPP design guidance](https://www.cencenelec.eu/media/CEN-CENELEC/CWAs/RI/2025/cwa18186_2025.pdf?ref=sorena.io) - The guidance describes supply-chain DPP information exchanges such as technical specifications, bill-of-materials content, material or chemical declarations, and tiered supplier-to-manufacturer data exchange.

## Validation checks for each supplier data field

Validate each supplier field as a structured record, not just as text to paste into the passport. The record should show what the value is, who supplied it, what product it belongs to, what evidence supports it, and who approved it for the current DPP version.

Use quality checks that match the DPP technical design requirements: completeness for the required field, consistency with the product identifier and passport level, machine-readable format where needed, source traceability, and controlled update rights.

- Field identity: data-field name, product group, passport level, unit of measure or format, and whether the field is required, optional, or voluntary.
- Evidence quality: source document title, issuer, issue date if present in the evidence, version, test or calculation method if stated, and whether the evidence covers the same product variant.
- Product consistency: match supplier part numbers and batch or item references to the manufacturer product identifier used in the DPP.
- Data quality: check that values are complete, internally consistent, not broader than the evidence, and not stale after a supplier change notice or engineering change.
- System quality: confirm that the field can be stored, searched, transferred, and updated in the passport data model without breaking the data carrier or resolver path.

- [Regulation (EU) 2024/1781 (ESPR)](https://eur-lex.europa.eu/eli/reg/2024/1781/oj/eng?ref=sorena.io) - Article 10 requires passport data to use open standards and be machine-readable, structured, searchable, and transferable where appropriate.

## Access class and update-rights review

Supplier data should be reviewed for access before it is published. ESPR allows access rights to vary by actor type, and DPP guidance distinguishes public information from restricted information made available to particular parties.

This review should happen before a supplier field is mapped into the passport, because the same evidence may contain public attributes, commercially sensitive details, authority-facing documentation, and personal data that should not be exposed through the same view.

- Public access: values intended for customers or general stakeholders, available without login or personal-data collection.
- Restricted access: supplier or technical data available only to approved economic operators, repairers, recyclers, market surveillance authorities, customs authorities, or other actors identified for that product group.
- Write access: define who may introduce, modify, or update the field and what approval is required before the update becomes live.
- Authority access: mark documents such as technical documentation, conformity information, or restricted compliance evidence that may need rapid retrieval for market surveillance or customs checks.
- Privacy and confidentiality: remove personal data unless explicit consent and a lawful basis apply, and separate trade-secret material from the public passport view.

## Approval record to keep with the supplier submission

Close the workflow with an approval record that can be traced back from the live DPP value to the supplier evidence. The record should be usable by product compliance, sustainability, master data, quality, and supply-chain teams without relying on private comments or undocumented emails.

Keep approval records separate from public passport content. The public DPP should expose the approved data and relevant access-controlled evidence; the internal record should explain how the organization validated the supplier submission and who approved the release.

- Record identifiers: supplier submission ID, product identifier, passport field ID, passport version, and affected model, batch, or item.
- Owner and approver: supplier source owner, internal data owner, product compliance reviewer, and final release approver.
- Evidence summary: source artifact, version, coverage statement, quality checks completed, unresolved limitations, and whether third-party verification was used.
- Access result: final access class, actors allowed to view or update the field, and whether authority-facing evidence is retrievable through the DPP system or another controlled channel.
- Release log: approval timestamp, release note, previous value if updated, reason for change, and trigger for revalidation such as supplier change, product change, delegated-act update, or evidence expiry.
