Authorisation
The substances specified in the Annex, belonging to the additive category ‘technological additives’ and to the functional group ‘anticaking agents’, are authorised as additives in animal nutrition, subject to the conditions laid down in that Annex.
Repeal of Regulation (EC) No 1810/2005
Regulation (EC) No 1810/2005 is repealed.
Transitional measures
1. The feed additives sodium ferrocyanide and potassium ferrocyanide, as authorised pursuant to Commission Regulation (EC) No 1810/2005, and premixtures containing those additives, which are produced and labelled before 4 November 2025 in accordance with the rules applicable before 4 May 2025 may continue to be placed on the market and used until the stocks concerned are exhausted. 2. Compound feed and feed materials containing the feed additives referred to in paragraph 1, which are produced and labelled before 4 May 2026 in accordance with the rules applicable before 4 May 2025 may continue to be placed on the market and used until the stocks concerned are exhausted if they are intended for food-producing animals. 3. Compound feed and feed materials containing the feed additives referred to in paragraph 1, which are produced and labelled before 4 May 2027 in accordance with the rules applicable before 4 May 2025 may continue to be placed on the market and used until the stocks concerned are exhausted if they are intended for non-food producing animals.
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.
