Commission Implementing Regulation (EU) No 1006/2013of 18 October 2013concerning the authorisation of L-cystine as a feed additive for all animal species(Text with EEA relevance) THE EUROPEAN COMMISSION,Having regard to the Treaty on the Functioning of the European Union,Having regard to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on additives for use in animal nutritionOJ L 268, 18.10.2003, p. 29., and in particular Article 9(2) thereof,Whereas:(1)Regulation (EC) No 1831/2003 provides for the authorisation of additives for use in animal nutrition and for the grounds and procedures for granting such authorisation.(2)In accordance with Article 7 of Regulation (EC) No 1831/2003 an application was submitted for the authorisation of L-cystine as a feed additive in the functional group "amino acids, their salts and analogues". That application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003.(3)That application concerns the authorisation of L-cystine as a feed additive for all animal species, to be classified in the additive category "nutritional additives".(4)The European Food Safety Authority ("the Authority") concluded in its opinion of 13 March 2013EFSA Journal 2013; 11(4):3173. that, under the proposed conditions of use, L-cystine does not have an adverse effect on animal health, human health or the environment and that it may be considered efficacious to contribute to the requirements for sulphur-containing amino acids in all animal species. The Authority does not consider that there is a need for specific requirements of post-market monitoring. It also verified the report on the method of analysis of the feed additive in feed submitted by the Reference Laboratory set up by Regulation (EC) No 1831/2003.(5)The assessment of that substance shows that the conditions for authorisation, provided for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. Accordingly, the use of that substance should be authorised, as specified in the Annex to this Regulation.(6)The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on the Food Chain and Animal Health,HAS ADOPTED THIS REGULATION:
Article 1The substance specified in the Annex, belonging to the additive category "nutritional additives" and to the functional group "amino acids, their salts and analogues", is authorised as an additive in animal nutrition subject to the conditions laid down in that Annex.
Article 2This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.
This Regulation shall be binding in its entirety and directly applicable in all Member States.Done at Brussels, 18 October 2013.For the CommissionThe PresidentJosé Manuel BarrosoANNEX
