of 29 Febr uary 2024
concer ning the author isation of lignosulphonate as a feed additiv e for all animal species 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION,
Havi ng regar d to the Treaty on the Functioning of the European Union,
Havi ng rega rd to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 Sept ember 2003 on 
additives for use in animal nutr ition (1), and in particular Article 9(2) thereof,
Whereas:
(1) Regulation (EC) No 1831/2003 provid es for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting such an author isation. Article 10(2) of that Regulation provides for the 
re-evaluation of additives author ised pursuant to Council Directive 70/524/EEC (2).
(2) Lignosulphonate was author ised without a time limit in accordance with Directive 70/524/EEC as a feed additive for 
all animal species. That substance was subsequently entered in the Registe r of feed additives as an existing product, in 
accordance with Article 10(1)(b) 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 lignosulphonate as a feed additive for all animal species. The 
applicant requeste d the additive to be classifie d in the additive cate gory ‘technological additives’ and in the 
functional group ‘binders’. The 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 Author ity’) concluded in its opinions of 6 July 2015 (3), 10 Januar y 
2020 (4)and 21 March 2023 (5)that, under the proposed conditions of use, lignosulphonate is safe for weaned 
piglets, pigs for fattening, chic kens for fattening, laying hens and cattle for fattening at a maximum cont ent of 
10 000 mg/kg compl ete feed and for all other animal species at a maximum cont ent of 8 000 mg/kg compl ete feed, 
for consumers and for the environment. It also concluded that solid forms of lignosulphonate should be regar ded as 
hazardous by inhalation. The Authority further concluded that the additive is effective as a pellet binder . 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.
(5) In view of the above, the Commission considers that lignosulphonate satisfies the conditions provided for in 
Article 5 of Regulation (EC) No 1831/2003. According ly, the use of that substance should be author ised as 
specifi ed in the Annex to this Regulation. In addition, the Commission considers that appropr iate prote ctive 
measures should be taken to prevent adverse effects on the health of the users of the additive.
(6) Since safet y reasons do not require the immediate application of the modifications to the conditions of author isation 
of the substance concer ned, it is appropr iate to provid e for a transitional period for inter ested parties to prepare 
themselves to meet the new requirements resulting from the author isation.

HAS ADOPTED THIS REGUL ATION:
Article 1
Author isation

the mark et and used until the existing stoc ks are exhaust ed.
2. Com pound feed and feed mater ials containing the substance specified in the Annex, which are produced and labelled 
before 21 March 2025 in accordance with the rules applicable before 21 March 2024 may continue to be placed on the 
mark et and used until the existing stoc ks are exhaust ed if they are intended for food-producing animals.
3. Com pound feed and feed mater ials containing the substance specified in the Annex, which are produced and labelled 
before 21 March 2026 in accordance with the rules applicable before 21 March 2024 may continue to be placed on the 
mark et and used until the existing stoc ks are exhaust ed if they are intended for non-f ood producing animals.

Analytical method (1)
For the determination of 
lignosulphonate in the feed additive:
— indirect determination by total 
ash and reducing sugars from
