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)  3-(Methy lthio) propionaldehyde, meth yl 3-(methy lthio) propionate, allylthiol, dimeth yl sulfide, dibutyl sulfi de, 
diallyl disulfide, diallyl trisulfid e, dimeth yl trisulfide, diprop yl disulf ide, allyl isothiocyanat e, dimethyl disulf ide, 
2-methyl benzene-1-thiol, S-meth yl butanethioate, allyl meth yl disulfi de, 3-(methylthio) propan-1-ol, 3- 
(meth ylthio) hexan-1-ol, 1-propane-1-thiol, diallyl sulfi de, 2,4-dithiapentane, 2-methyl -2-(methyldithio) propanal, 
2-methyl propane-1-thiol, methylsulfinyl methane, propane-2-thiol, 3,5-dimeth yl-1,2,4-tr ithiolane and 2-methyl- 
4-prop yl-1,3-o xathiane (‘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 classified in the additive categor y ‘sensor y additives ’. That 
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 Authority (‘the Authority’) concluded in its opinion of 17 Apr il 2013 (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 envi ronment. For allyl isothiocyanat e, the Author ity stated that, although additional 
exposure to that substance through its low use level in animal feeds would not substantially increase consumer 
exposure, the estimate d exposure of consumers is already higher than the acceptable daily intake. For allyl 
isothiocyanat e and 2-methyl propane-1-thiol maximum cont ents should be set up to ensure consumer safety and 
environmental prote ction, respectively . The Author ity further concluded that the function of the substances 
concer ned in feed is similar to that on food. The Author ity has already concluded that for food the substances 
concer ned are efficacious, as it increases the food smell or palatability . Theref ore, that conclusion can be 
extrapolat ed for feed. The Auth ority could not conclude on the safety of the substances concer ned used in wate r 
for drinking. However , those substances can be used within compo und feeds whic h are subsequently 
administ ered via wate r. 17.1.2017 L 13/186 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 ing-stuffs (OJ L 270, 14.12.1970, p. 1). 
(3)EFSA Jour nal 2013;11(5):3208. (5)  Restr ictions and conditions should be provided for to allow better control. For all the substances excep t allyl 
isothiocyanat e and 2-methylpropane-1-thiol, since safety reasons do not require the setting of a maximum 
cont ent and, taking into account the re-evaluation perf ormed by the Auth ority, recommended contents should be 
indicated on the label of the additive. Where such conte nts are excee ded, certain information should be indicate d 
on the label of premixtures, compo und feeds and feed mat erials. 
(6)  The Author ity concluded that the substances concer ned are to be considered as being irritant to skin, eyes and 
respirato ry tract and as a skin sensitiser . Consequently , appropr iate prot ective measures should be take n. The 
Author ity does not consider that there is a need for specifi c requirements of post-market monitori ng. It also 
verified the repor t on the method of analysis of the feed additives in feed submitte d by the Reference Laborat ory 
set up by Regulation (EC) No 1831/2003. 
(7)  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. 
(8) 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. 
(9)  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.

2. Com pound feed and feed mater ials containing the substances as specif ied 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
