Commission Delegated Regulation (EU) 2025/1463of 23 May 2025amending Regulation (EU) 2024/1735 of the European Parliament and of the Council as regards the identification of sub-categories within net-zero technologies and the list of specific components used for those technologies(Text with EEA relevance)

Commission Delegated Regulation (EU) 2025/1463 of 23 May 2025 amending Regulation (EU) 2024/1735 of the European Parliament and of the Council as regards the identification of sub-categories within net-zero technologies and the list of specific components used for those technologies (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) 2024/1735 of the European Parliament and of the Council of 13 June 2024 on establishing a framework of measures for strengthening Europe’s net-zero technology manufacturing ecosystem and amending Regulation (EU) 2018/1724 OJ L, 2024/1735, 28.6.2024, ELI: http://data.europa.eu/eli/reg/2024/1735/oj. and in particular Article 46(7) thereof, Whereas: (1) Regulation (EU) 2024/1735 established a legal framework that strengthens the Union’s resilience and security of supply in the field of net-zero technologies, by enhancing the Union’s capacity for manufacturing, deployment and innovation in that field. (2) The Annex to Regulation (EU) 2024/1735 sets out in a non-exhaustive manner a list of specific components considered to be primarily used for the production of net-zero technologies. (3) Specific components and specific machinery not included in that list may still fall within the scope of Regulation (EU) 2024/1735 if the project promoter can provide evidence, for example market studies or off-take agreements, to a national competent authority showing that the specific components or machinery are primarily used for the production of net-zero technologies. (4) A comprehensive assessment, based on a methodological analysis of the supply chains of the net-zero technologies, has been carried out by the Commission. That assessment took into account in particular the commercial availability of the components, the appropriate level of detail and developments in technology. (5) To identify specific components considered to be primarily used for the production of net-zero technologies, four criteria were applied in the assessment, namely their specific nature; their commercial availability; the fact that they are always primarily used for that production; and their essential character. As a first step, each of the net-zero technologies and, where necessary, sub-categories were further defined using the criteria listed above and in line with the definitions of those net-zero technologies in Regulation (EU) 2024/1735. As a second step, each sub-category was analysed to identify the components fulfilling the four criteria used. Components fulfilling those criteria were considered as primarily used for the production of net-zero technologies. (6) An additional column Final products should be added in the Annex to Regulation (EU) 2024/1735 for explanatory purposes. That additional column allows to put the elements in the list of primarily used components in context and therefore enhances the comprehensibility of the Annex. (7) Regulation (EU) 2024/1735 should therefore be amended accordingly,

ANNEX List of final products and specific components considered to be primarily used for the production of net-zero technologies The term equivalent refers to similar steps or key enabling technologies needed for thin-film, organic, tandem or other PV technologies. Batteries as defined in Article 3(13), (14) and (15) of Regulation (EU) 2023/1542 of the European Parliament and of the Council of 12 July 2023 concerning batteries and waste batteries. The term electric road system (also known as dynamic charging) refers to equipment along the road that supplies power to vehicles while they are in motion. That final product includes both conductive and inductive charging. The term heater refers to low (up to 200 °C) and medium (200 to 500 °C) temperature applications. The term furnace refers to high (500 to 1000 °C) and very high (above 1000 °C) temperature applications.
