Article 5 — Data flows for the purpose of the common data platform

1. At the Commission’s request, the Agencies shall host and maintain chemicals data generated as part of Union, national or international law, programmes or from research activities corresponding to their mandate and to the type of data they already hold. In addition, Agencies may, in accordance with their mandate, host and maintain chemicals data submitted to them by Member States or other parties, including national agencies, research institutes and third-country organisations. 2. Where the Commission or one of the Agencies holds data or information as referred to in Article 3(2) or (3), it shall make those data available to the ECHA, which shall incorporate them into the common data platform. The Commission and the Agencies shall provide the data or information to the ECHA in a standard format, where available, together with the relevant context data as referred to in Article 4(5), point (c). Where those data are or that information is not made available to the public under the originating Union act, the Commission and the Agencies shall so indicate. 3. The ECHA shall host and maintain occurrence data related to workplace monitoring, including occupational human biomonitoring data. 4. The EEA shall host and maintain human biomonitoring data, occurrence data for the environment and occurrence data related to indoor air quality. 5. From 1 January 2026, researchers or research consortia funded by Union framework programmes or national programmes shall make all human biomonitoring data they collect or generate available to the EEA. The EEA shall host that data. For human biomonitoring data constituting personal data, the EEA shall specify which type of data are to be made available to it. 6. From 1 January 2026, researchers or research consortia funded by Union framework programmes shall make all environmental sustainability-related data they collect or generate available to the ECHA. The ECHA shall host that data. 7. The Commission and the Agencies shall provide the necessary technical cooperation to the ECHA to enable the chemicals data provided in accordance with paragraph 2 to be incorporated into and published through the common data platform. The ECHA shall provide support to the Authorities and national agencies to facilitate the incorporation of the chemicals data provided in accordance with paragraph 2. 8. For the purpose of paragraph 2, the Commission and the Agencies shall make chemicals data that they have collected or received available to the ECHA without delay once they have performed validity and confidentiality assessments of the data in accordance with applicable rules and once they have incorporated the corresponding dataset into the common data platform. 9. The Authorities and national agencies shall ensure, when making data available to the ECHA, that such data are downloadable, machine readable and interoperable. They shall curate and validate the data in an appropriate manner before providing them to the ECHA. 10. Without prejudice to Article 6(11), the Commission and the Agencies shall act as data controller for any personal data they provide to the ECHA for incorporation into the common data platform.
