Commission Implementing Regulation (EU) 2025/2513of 11 December 2025concerning the authorisation of copper(II)-betaine complex as a feed additive for all animal species(Text with EEA relevance)

Commission Implementing Regulation (EU) 2025/2513 of 11 December 2025 concerning the authorisation of copper(II)-betaine complex as a feed additive for all animal species (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on additives for use in animal nutrition OJ L 268, 18.10.2003, p. 29, ELI: https://eur-lex.europa.eu/eli/reg/2003/1831/oj/eng. , and in particular Article 9(2) thereof, Whereas: (1) Regulation (EC) No 1831/2003 provides for the authorisation of additives for use in animal nutrition and for the grounds and procedures for granting such authorisation. (2) In accordance with Article 7 of Regulation (EC) No 1831/2003, an application was submitted for the authorisation of copper(II)-betaine complex. The application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003. (3) That application concerns the authorisation of copper(II)-betaine complex as a feed additive for all animal species, requesting that additive to be classified in the additive category nutritional additives and in the functional group compounds of trace elements. (4) The European Food Safety Authority (the Authority) concluded in its opinion of 11 January 2023 EFSA Journal, 2023;21(2):7817, https://doi.org/10.2903/j.efsa.2023.7817. that, under the proposed conditions of use, copper(II)-betaine complex is safe for all animal species as well as for the consumers. In regard to the environment, the Authority concluded that at the proposed use levels the substance is considered safe for the terrestrial species and the land-based aquaculture systems. The data available did not allow the conclusion to be made on the safety of the additive for marine sediment, when it is used in sea cages. The Authority also concluded that the additive exposure by inhalation is likely. The additive is irritant to eyes and non-irritant to skin. The additive is considered to be a skin and respiratory sensitiser, due to the presence of nickel. The Authority further concluded that based on the data available, the efficacy of the additive cannot be demonstrated. In its second opinion of 15 November 2023 EFSA Journal, 2023;21:e8460, https://doi.org/10.2903/j.efsa.2023.8460. , the Authority concluded that the use of the additive at the proposed conditions of use in marine aquaculture does not a pose a risk to the marine sediment compartment. The Authority reiterated its previous conclusion that, based on the data available, the efficacy of the additive cannot be demonstrated. In its third opinion of 6 May 2025 EFSA Journal, 2025;23:e9469, https://doi.org/10.2903/j.efsa.2025.9469. , the Authority concluded that that the additive is efficacious as a source of copper for all animal species. It did not consider that there is a need for specific requirements of post-market monitoring. The Authority also verified the report on the method of analysis of the feed additive in feed submitted by the Reference Laboratory set up by Regulation (EC) No 1831/2003.

(5) In view of the above, the Commission considers that copper(II)-betaine complex satisfies the conditions provided for in Article 5 of Regulation (EC) No 1831/2003. Accordingly, the use of that substance should be authorised for all animal species. In addition, the Commission considers that appropriate protective measures should be taken to prevent adverse effects on the health of the users of the additive. (6) The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Plants, Animals, Food and Feed, HAS ADOPTED THIS REGULATION:

Article 1

1. The additive shall be incorporated into feed in the form of a premixture.
2. The following information shall be included in the labelling: For feed for sheep, if the level of copper in the feed exceeds 10 mg/kg: The level of copper in this feed may cause poisoning in certain breeds of sheep. For feed for bovines after the start of rumination, if the level of copper in the feed is less than 20 mg/kg: The level of copper in this feed may cause copper deficiencies in cattle grazing pastures with high contents of molybdenum or sulphur.
3. Users of the additive and premixtures, feed business operators shall establish operational procedures and appropriate organisational measures to address the potential risks of exposure by inhalation, dermal contact or eyes contact, in particular due to the content of nickel. Where such risks cannot be eliminated by these procedures and measures, the additive and premixtures shall be used with appropriate personal protective equipment, including eyes, skin and breathing protection. 1 January 2036Other bovines30Ovines15Caprines35Piglets suckling and weanedUp to 4 weeks after weaning150Piglets From 5-th week after weaning up to 8 weeks after weaning 100Crustaceans50Other animal species and categories25
