Renewal 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.
Repeal 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Implementing Regulations (EU) No 1222/2013 and (EU) No 305/2014 are repealed.
Transitional 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.
Entry 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.
