THE EUR OPEAN COMMISSION, 
Having regar d to the Treaty on the Functioning of the European Union, 
Having regar d to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 
on additives for use in animal nutr ition (1), and in particular Article 9(2) thereof, 
Whereas: 
(1)  Regulation (EC) No 1831/2003 provides for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting such author isation. Article 10 of that Regulation provides for the re- 
evaluation of additives author ised pursuant to Council Directive 70/524/EEC (2). 
(2) 2-Methy lpropan-1-ol, isopentanol, 3,7-dimethyl octan-1-ol, 2-ethy lhexan-1-ol, 2-methyl propanal, 3-methyl ­
butanal, 2-meth ylbutyraldehyde, 3-meth ylbutyr ic acid, 2-meth ylvaler ic acid, 2-ethy lbutyr ic acid, 2-methyl butyr ic 
acid, 2-methyl heptanoic acid, 4-methyl nonanoic acid, 4-methyl octanoic acid, isobutyl acetate, isobutyl butyrate , 
3-methyl butyl hexanoate, 3-methyl butyl dodecanoat e, 3-meth ylbutyl octanoate, 3-methyl butyl propionat e, 
3-methyl butyl formate, glyceryl tributyrate, isobutyl isobutyrate , isopentyl isobutyrate, isobutyl isovalerate , 
isopentyl 2-methylbutyrat e, 2-methylbutyl isovalerate and 2-methylbutyl butyrate, herereinaf ter referred to as ‘the 
substances concer ned’ were author ised without a time limit in accordance with Directive 70/524/EEC as feed 
additives for all animal species. Those products were subsequently entered in the Regist er of feed additives as 
existing products, in accordance with Article 10(1) of Regulation (EC) No 1831/2003. 
(3)  In accordance with Article 10(2) of Regulation (EC) No 1831/2003 in conjunction with Article 7 thereof, an 
application was submitted for the re-evaluation of the substances concer ned as feed additives for all animal 
species. The applicant requested those additives to be classifie d in the additive catego ry ‘sensor y additives’. This 
application was accompan ied by the particulars and documents required under Article 7(3) of Regulation (EC) 
No 1831/2003. 
(4)  The European Food Safety Auth ority (‘the Author ity’) concluded in its opinion of 17 October 2012 (3) that, 
under the proposed conditions of use in feed, the substances concer ned do not have adverse effects on animal 
health, human health or the environment. The Author ity further concluded that those substances are flavouri ng 
agents author ised in food for whic h the efficacy is demonstrated as the functions of the additive applied for feed 
use and descr ibed for food use are similar . 
(5)  The Author ity concluded that no safety concer ns would arise for users provided that appropr iate prote ctive 
measures are take n. The Author ity does not consider that there is a need for specifi c requirements of post-market 
monitoring. It also verified the repor t on the Method of analysis of the feed additives in feed submitte d by the 
Reference Laboratory set up by Regulation (EC) No 1831/2003. 17.1.2017 L 13/80 Official Jour nal of the European Union EN     
(1)OJ L 268, 18.10.2003, p. 29. 
(2)Council Directive 70/524/EEC of 23 November 1970 concer ning additives in feed ingstuffs (OJ L 270, 14.12.1970, p. 1). 
(3)EFSA Journal 2012;10(10):2927. (6)  The assessment of the substances concer ned shows that the conditions for author isation, as provided for in 
Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the use of those substances should be 
author ised as specified in the Annex to this Regulation. Maximum recommended contents should be set up for 
those substances. Those substances may be used within a compo und feed subsequently administered via water . 
(7) Since safety reasons do not require the immediate application of the modifi cations to the conditions of author is­
ation for the substances concer ned, it is appropr iate to allow a transitional period for interest ed parties to 
prepare themselves to meet the new requirements resulting from the author isation. 
(8)  The measures provided 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 
Author isation 
The substances specifi ed in the Annex, belonging to the additive catego ry ‘sensor y additives ’ and to the functional group 
‘flavouri ng compounds’, are author ised as feed additives in animal nutr ition subject to the conditions laid down in that 
Annex. 
Article 2 
Transitional measures 
1. The substances specifi ed in the Annex and premixtures containing those substances, whic h are produced and 
labelled before 6 August 2017 in accordance with the rules applicable before 6 Febr uary 2017 may continue to be 
placed on the mark et and used until the existing stoc ks are exhausted. 
2. Com pound feed and feed mate rials containing the substances specified in the Annex which are produced and 
labelled before 6 Febr uary 2018 in accordance with the rules applicable before 6 Febr uary 2017 may continue to be 
placed on the mark et and used until the existing stoc ks are exhausted if they are intende d for food-producing animals. 
3. Com pound feed and feed mate rials containing the substances specified in the Annex which are produced and 
labelled before 6 Febr uary 2019 in accordance with the rules applicable before 6 Febr uary 2017 may continue to be 
placed on the mark et and used until the existing stocks are exhaust ed if they are intende d for non-f ood-producing 
animals.
