(Text with EEA relevance) 
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 provi des for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting such author isation. 
(2) In accordance with Article 7 of Regulation (EC) No 1831/2003 an application was submitte d for the author is­
ation of a preparation of dolomite-magnesit e. That application was accompanied by the particulars and 
documents required under Article 7(3) of Regulation (EC) No 1831/2003. 
(3)  That application concer ns the author isation of a preparation of dolomite- magnesite as a feed additive for all 
animal species to be classifie d in the additive cate gory ‘technological additives ’. 
(4)  The preparation of dolomit e-magnesite belonging to the additive categor y of ‘technological additives’, was 
previously author ised for 10 years as a feed additive for dair y cows and other ruminants for dair y production, 
weaned piglets and pigs for fattening by Commission Implementing Regulation (EU) 2016/1964 (2). 
(5)  The European Food Safety Author ity (‘the Authority’) concluded in its opinions of 17 Apr il 2018 (3) and 
25 Januar y 2017 (4) that, under the proposed conditions of use, the preparation of dolomite- magnesite does not 
have an adverse effect on animal health, human health or the environment. The Auth ority has also concluded 
that it is effective as an anti-caking agent. 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 additive 
in feed submitted by the Reference Laboratory set up by Regulation (EC) No 1831/2003. 
(6)  The assessment of the preparation of dolomite-magnesit e shows that the conditions for author isation, as 
provid ed for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the use of that preparation 
should be author ised as specifi ed in the Annex to this Regulation. 
(7)  The measures provi ded for in this Regulation are in accordance with the opinion of the Standing Committee on 
Plants, Animals, Food and Feed, 
HAS ADOPTED THIS REGUL ATION: 
Article 1 
The preparation specifi ed in the Annex, belonging to the additive catego ry ‘technological additives ’ and to the functional 
group ‘anticaking agents’, is author ised as an additive in animal nutr ition, subject to the conditions laid down in the 
Annex. 19.10.2018 L 262/20 Official Jour nal of the European Union EN

(2)Commission Implementing Regulation (EU) 2016/1964 of 9 November 2016 concer ning the author isations of a preparation of 
dolomite- magnesite for dair y cows and other ruminants for dair y production, weaned piglets and pigs for fattening and a preparation of 
montmor illonite-illit e for all animal species as feed additives (OJ L 303, 10.11.2016, p. 7).
