COMMISSION IMPLEMENTING REGUL ATION (EU) 2023/255 
of 6 Febr uary 2023
concer ning the renewal of the author isation of naringin as a feed additiv e for all animal species and 
repealing Implementing Regulation (EU) No 870/2012 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION,
Havi ng regar d to the Treaty on the Functioning of the European Union,
Havi ng rega rd to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 Sept ember 2003 on 
additives for use in animal nutr ition (1), and in particular Article 9(2) thereof,
Whereas:
(1) Regulation (EC) No 1831/2003 provid es for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting and renewing such author isation.
(2) Naringin was author ised for a period of 10 years as a feed additive for all animal species by Commission 
Implementing Regulation (EU) No 870/2012 (2).
(3) In accordance with Article 14(1) of Regulation (EC) No 1831/2003, an application was submitted for the renewal of 
the author isation of naringin as a feed additive for all animal species, requesting the additive to be classif ied in the 
additive cate gory ‘sensor y additives ’ and in the functional group ‘flavouri ng compo unds ’. That application was 
accompan ied by the particulars and documents required under Article 14(2) of that Regulation.
(4) The European Food Safety Author ity (‘the Author ity’) concluded in its opinion of 24 Marc h 2022 (3)that the 
applicant has provid ed evidence that the additive remains safe for all animal species, the consumers and the 
environment under the conditions of use currently author ised. It also concluded that naringin does not cause severe 
irritation or corrosion to eyes, is not irritant to skin and is not classified as a dermal sensitiser , but in the absence of 
data it could not conclude on the possible respirato ry sensitisation of the additive.
(5) In accordance with Article 5(4), point (c), of Commission Regulation (EC) No 378/2005 (4), the Reference 
Laboratory set up by Regulation (EC) No 1831/2003 considered that the conclusions and recommendations 
reach ed in the previous assessment are applicable for the current application.
(6) The assessment of naringin shows that the conditions for author isation, as provi ded for in Article 5 of Regulation 
(EC) No 1831/2003, are satisfied. According ly, the author isation of that additive should be renewed.
(7) The Commission considers that appropr iate protect ive measures should be taken to prevent adverse effects on 
human health, in particular as regards the users of the additive. Those prote ctive measures should compl y with 
Union legislation on worker safety requirements.

(2)Commission Implementing Regulation (EU) No 870/2012 of 24 Sept ember 2012 concer ning the author isation of naringin as a feed 
additive for all animal species (OJ L 257, 25.9.2012, p. 10).

(4)Commission Regulation (EC) No 378/2005 of 4 March 2005 on detailed rules for the implement ation of Regulation (EC) 
No 1831/2003 of the European Parliament and of the Council as regards the duties and tasks of the Community Reference 
Laborato ry concer ning applications for author isations of feed additives (OJ L 59, 5.3.2005, p. 8).EN Offi cial Jour nal of the European Union 7.2.2023 L 35/11  (8) Certain conditions should be provid ed for to allow better control. In particular , a recommended maximum content 
should be indicated on the label of the additive. Where such conte nt is excee ded, certain information should be 
indicated on the label of premixtures.
(9) As a consequence of the renewal of the author isation of naringin as a feed additive, Implementing Regulation (EU) 
No 870/2012 should be repealed.
(10) Since safet y reasons do not require the immediate application of the modifications to the conditions of author isation 
of naringin, it is appropr iate to provide for a transitional period for inter ested parties to prepare themselves to meet 
the new requirements resulting from the renewal of the author isation.
(11) The measures provid ed for in this Regulation are in accordance with the opinion of the Standing Committ ee on 
Plants, Animals, Food and Feed,
HAS ADOPTED THIS REGUL ATION:
Article 1
Renewal of the author isation
The author isation of the substance specifi ed in the Annex, belonging to the additive catego ry ‘sensor y additives ’ and to the 
functional group ‘flavouring compounds’, is renewed subject to the conditions laid down in that Annex.
Article 2
Repeal
Implementing Regulation (EU) No 870/2012 is repealed.
Article 3
Transitional measures
1. The substance specifi ed in the Annex and premixtures containing that substance, whic h are produced and labelled

mark et and used until the existing stoc ks are exhaust ed.
2. Com pound feed and feed mater ials containing the substance specified in the Annex, which are produced and labelled 
before 27 Febr uary 2024 in accordance with the rules applicable before 27 Febr uary 2023 may continue to be placed on

3. Com pound feed and feed mater ials containing the substance specified in the Annex, which are produced and labelled 
before 27 Febr uary 2025 in accordance with the rules applicable before 27 Febr uary 2023 may continue to be placed on 
the mark et and used until the existing stoc ks are exhaust ed if they are intended for non-f ood producing animals.
