Glossary · DPP: data, identifiers and standards
UpdatedHarmonized DPP standards (EN 18216, EN 18219–18223)
Also known as: DPP standards, EN 18216, EN 18219, EN 18220, EN 18221, EN 18222, EN 18223, CEN/CENELEC JTC 24 standards
The harmonized DPP standards are European standards developed by CEN/CENELEC JTC 24 for the technical design of the digital product passport and listed in Commission Implementing Decision (EU) 2026/1736, with their references published in the Official Journal of the European Union. Applying them may support presumption of conformity with the ESPR requirements they cover.

In one sentence
EN 18216, 18219, 18220, 18221, 18222 and 18223 are cited DPP standards that support presumption of conformity for the ESPR requirements they cover.
Example
A service provider builds its passport platform to EN 18222:2026 for APIs and EN 18221:2026 for data storage and archiving, and states both standards and their editions in its conformity documentation.
The standards
| Standard | Subject |
|---|---|
| EN 18216:2026 | Data exchange protocols |
| EN 18219:2026 | Unique identifiers |
| EN 18220:2026 | Data carriers |
| EN 18221:2026 | Data storage, archiving and data persistence |
| EN 18222:2026 | Application programming interfaces (APIs) for lifecycle management and searchability |
| EN 18223:2026 | System interoperability |
How it applies
- Presumption of conformity: For the ESPR requirements each standard covers, applying the cited edition may support presumption of conformity. The presumption is limited to those requirements.
- Limits: The standards solve technical interoperability. They do not decide who owns the data, who may see it, which system is the source of truth or how changes are approved. The security, access and integrity standards EN 18239:2026 and EN 18246:2026 are published but not cited in the Official Journal, so they give no presumption of conformity.
- Delegated acts: Product-group requirements come from each ESPR delegated act; the standards describe how the passport system works, not what a given product's passport must contain.
- Technical documentation: Record the standards, editions and covered requirements the same way as for any harmonized standard.
Compared with the USA, Canada and China
The USA and Canada rely on industry standards such as GS1 identifiers for traceability, without a legal presumption tied to a passport. China develops its own national standards for identifiers and battery coding. Only the EU links cited standards to a legal presumption for a product passport.
