This publication has been prepared under a mandate given to the European Standards Organizations by the European Commission and the European Free Trade Association. It is intended to support requirements of the EU legislation detailed in the European Foreword. A European Annex, usually Annex ZA or ZZ, describes how this publication relates to that EU legislation.

For the Great Britain market (England, Scotland and Wales), if UK Government has designated this publication for conformity with UKCA marking (or similar) legislation, it may contain an additional National Annex. Where such a National Annex exists, it shows the correlation between this publication and the relevant UK legislation. If there is no National Annex of this kind, the relevant Annex ZA or ZZ in the body of the European text will indicate the relationship to UK regulation applicable in Great Britain. References to EU legislation may need to be read in accordance with the UK designation and the applicable UK law. Further information on designated standards can be found at www.bsigroup.com/standardsandregulation.

For the Northern Ireland market, UK law will continue to implement relevant EU law subject to periodic confirmation. Therefore Annex ZA/ZZ in the European text, and references to EU legislation, are still valid for this market.

UK Government is responsible for legislation. For information on legislation and policies relating to that legislation, consult the relevant pages of www.gov.uk.

Compliance with a British Standard cannot confer immunity from legal obligations.

This British Standard was published under the authority of the Standards Policy and Strategy Committee on 31 May 2026.

This European Standard was approved by CEN on 3 May 2026.

CEN and CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN and CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN and CENELEC member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.

CEN and CENELEC members are the national standards bodies and national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and United Kingdom.

Introduction

0.1 Background

A digital product passport (DPP) is a key enabling mechanism to make product information traceable and accessible across value chains - supporting economic operators, manufacturers, distributors, repairers, recyclers and consumers to make informed decisions and to support a circular economy. The implementation of digital product passports will be carried out progressively. Sector-specific initiatives will determine the precise DPP content and requirements for individual product groups.

To support the implementation of DPPs, 8 standards have been developed so far:

EN 18219:2026 – Digital product passport – Unique identifiers
EN 18220:2026 – Digital product passport – Data carriers
EN 18216:2026 – Digital product passport – Data exchange protocols
EN 18222: 2026 – Digital Product Passport – Application Programming Interfaces (APIs) for the product passport lifecycle management and searchability (this document)
EN 18223:2026 – Digital Product Passport – System interoperability
EN 18221:2026 – Digital product passport – data storage, archiving, and data persistence
EN 18239:‑1 – Digital Product Passport – access rights management, information system security, and business confidentiality
EN 18246:‑2 – Digital Product Passport – Data authentication, reliability and integrity

0.2 Overview

The Ecodesign for Sustainable Products Regulation (ESPR) is an initiative by the European Commission aimed at promoting sustainable products by setting comprehensive requirements for product design, production, and lifecycle management. Central to this initiative is the digital product passport (DPP), which tracks and provides essential information about a product's sustainability attributes. Beside of that also other data can be stored in a DPP depending on future delegated acts and the needs of economic operators.

This document introduces the specifications for the API of the DPP, as mandated by the ESPR. The API is designed to enhance the searchability of DPPs and to support interactions throughout the lifecycle of a product's DPP. Furthermore, it also provides an API to register a DPP at the DPP registry.

The API methods are presented on a technology-neutral level, detailing the expected inputs and outputs for each method. A detailed technological implementation using a REST-HTTP API is described in the Clause 8, providing guidelines for developers to implement the functionality effectively within their specific environments.

The specification document of EN 18223 describes the logical content of the payload that is used by the API. EN 18216 defines the basic principles of the exchange protocol and the allowed serialization formats of the payload data. Security requirements need to be followed based on the specification document of EN 182462.

1 Scope

This document aims to standardize the specifications for the API of the digital product passport (DPP) as mandated by the ESPR of the European Commission. The purpose of this API is to facilitate the searchability of DPPs, as well as to provide the necessary means for interactions throughout the lifecycle of a product's DPP.
