Commission Implementing Regulation (EU) 2025/2186 of 29 October 2025 concerning the renewal of the authorisation of propionic acid, sodium propionate and ammonium propionate as feed additives for all terrestrial animal species and repealing Implementing Regulations (EU) No 1222/2013 and (EU) No 305/2014

Article 1Renewal of the authorisation

The authorisation of the substances specified in the Annex, belonging to the additive category ‘technological additives’ and to the functional group ‘silage additives, is renewed subject to the conditions laid down in that Annex.

Article 2Repeal of Implementing Regulations (EU) No 1222/2013 and (EU) No 305/2014

Implementing Regulations (EU) No 1222/2013 and (EU) No 305/2014 are repealed.

Article 3Transitional measures

The feed additives propionic acid, sodium propionate and ammonium propionate, as authorised by Implementing Regulations (EU) No 1222/2013 and (EU) No 305/2014 and feed containing them, which are intended for all terrestrial animal species, and which are produced and labelled before 19 November 2026 in accordance with the rules applicable before 19 November 2025 may continue to be placed on the market and used until the stocks concerned are exhausted.

Article 4Entry into force

This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.
