COMMI SSION IMPLEMENTING REGUL ATION (EU) 2018/1533 
of 12 Oct ober 2018 
concer ning the author isation of sodium alginate as a feed additiv e for cats, dogs, other 
non-fo od-producing animals and fish and pota ssium alginate as a feed additiv e for cats and dogs 
(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 potassium alginat e. 
(3)  Article 10 of Regulation (EC) No 1831/2003 provi des for the re-evaluation of additives author ised pursuant to 
Council Directive 70/524/EEC (2). Sodium alginat e was author ised without a time limit by Directive 70/524/EEC 
as feed additive for fish, pets and other non-f ood-producing animals. The additive was subsequently entered in 
the Register of feed additives as existing product, in accordance with Article 10(1) of Regulation (EC) 
No 1831/2003. 
(4)  In accordance with Article 10(2) of Regulation (EC) No 1831/2003 in conjunction with Article 7 thereof, 
an application was submitte d for the re-evaluation of sodium alginate as feed additive for pets and other 
non-f ood-producing animals and fish. 
(5)  The applications concer n the author isation of potassium alginate as a feed additive for cats and dogs, and sodium 
alginat e as a feed additive for cats, dogs, other non-f ood-producing animals and fish, to be classified in the 
additive catego ry ‘technological additives’. Those applications were accompan ied by the particulars and 
documents required under Article 7(3) of Regulation (EC) No 1831/2003. 
(6)  The European Food Safety Author ity (‘the Author ity’) concluded in its opinion of 5 July 2017 (3) that, under the 
proposed conditions of use, potassium alginate and sodium alginat e do not have an adverse effect on animal 
health, human health or the environment. The Author ity also concluded that the potassium alginate and sodium 
alginat e concer ned are effective as stabilisers, thickeners , gelling agents and binders. The Auth ority 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 submitte d by the Reference Laboratory set up by Regulation 
(EC) No 1831/2003. 
(7)  The assessment of the additives concer ned 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 additives should be author ised 
as specifi ed in the Annex to this Regulation. 
(8)  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 
Author isation 
The additives specifi ed in the Annex, belonging to the additive categor y ‘technological additives ’ and to the functional 
group ‘stabilisers’, ‘thic keners’, ‘gelling agents’ and ‘binders’ are author ised as additives in animal nutr ition, subject to the 
conditions laid down in that Annex. 15.10.2018 L 257/13 Official Jour nal of the European Union EN

Transitional measures 
Sodium alginat e specified in the Annex and premixtures containing that additive, which are produced and labelled 
before 4 May 2019 in accordance with the rules applicable before 4 November 2018 may continue to be placed on the 
mark et and used until the existing stoc ks are exhaust ed. 
Feed mater ials and compo und feed containing sodium alginat e specified in the Annex which are produced and labelled 
before 4 November 2019 in accordance with the rules applicable before 4 November 2018 may continue to be placed 
on the market and used until the existing stoc ks are exhausted if they are intended for food producing animals. 
Feed mater ials and compo und feed containing sodium alginat e specified in the Annex which are produced and labelled 
before 4 November 2020 in accordance with the rules applicable before 4 November 2018 may continue to be placed 
on the market and used until the existing stoc ks are exhausted if they are intended for non-f ood-producing animals.
