Renewal of the authorisation
The authorisation of the substance specified in the Annex, belonging to the additive category ‘technological additives’, functional group ‘preservatives’ and to the additive category ‘sensory additives’, functional group ‘flavouring compounds’, is renewed subject to the conditions laid down in that Annex.
Repeal of Implementing Regulation (EU) No 1078/2013
Implementing Regulation (EU) No 1078/2013 is repealed.
Amendment to Implementing Regulation (EU) 2017/56
In the fifth column of the entry 2b08025 of the Annex to Implementing Regulation (EU) 2017/56, the words ‘All animal species’ are replaced by the words ‘Aquatic animal species’.
Transitional measures
1. The feed additive fumaric acid, as authorised by Implementing Regulations (EU) No 1078/2013 and (EU) 2017/56 and premixtures containing that additive, which are intended for terrestrial animal species, and which are produced and labelled before 16 August 2026 in accordance with the rules applicable before 16 February 2026, 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 additive referred to in paragraph 1, which are produced and labelled before 16 February 2027 in accordance with the rules applicable before 16 February 2026, may continue to be placed on the market and used until the stocks concerned are exhausted if they are intended for food-producing terrestrial animals. 3. Compound feed and feed materials containing the feed additive referred to in paragraph 1, which are produced and labelled before 16 February 2028 in accordance with the rules applicable before 16 February 2026, may continue to be placed on the market and used until the stocks concerned are exhausted if they are intended for non-food producing terrestrial 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.

In the directions for use of the additive and premixtures, the storage conditions and the stability to heat treatment shall be indicated. 2. The simultaneous use of fumaric acid with other sources of fumaric acid is permitted, only if the amount of fumaric acid in feed materials and compound feed is lower than the one resulting from the use of the additive at the maximum or recommended content for the respective animal species or category. 3. Indicate in the instructions for use of the additive, premixture and related feedingstuffs for food-producing animals: ‘The simultaneous use of different organic acids or their salts is contraindicated, where one or more of them is used at or near the maximum permitted content.’ 4. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from their use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal skin, eye and breathing protective equipment. 16 February 2036 Young mammals fed with milk replacers 10 000 ( 2 ) All other terrestrial animal species — Identification number of the feed additive Name of the additive Composition, chemical formula, description, analytical method Species or category of animal Maximum age Minimum content Maximum content Other provisions End of period of authorisation mg of additive/kg of complete feed with a moisture content of 12 % Category: Sensory additives.
