Commission Implementing Regulation (EU) 2025/2183 of 29 October 2025 concerning the renewal of the authorisation of L-valine produced with Corynebacterium glutamicum KCCM 80058 as a feed additive for all animal species and repealing Implementing Regulation (EU) No 848/2014
Issued by European Commission
· Directorate-General for Health and Food Safety
**Executive Summary**
This is a Commission Implementing Regulation (EU) 2025/2183, issued on 29 October 2025. It concerns the renewal of the authorisation of L-valine produced with Corynebacterium glutamicum KCCM 80058 as a feed additive for all animal species. The regulation repeals Implementing Regulation (EU) No 848/2014.
**Key Points / Main Content**
* **Renewal of Authorisation:** The authorisation of L-valine produced with Corynebacterium glutamicum KCCM 80058 is renewed under the category of "nutritional additives" and the functional group of "amino acids, their salts and analogues," subject to conditions specified in the annex of the regulation.
* **Repeal:** Implementing Regulation (EU) No 848/2014 is repealed.
* **Transitional Measures:**
* L-valine produced and labelled before 19 May 2026, under the old rules, may be placed on the market and used until stocks are exhausted.
* Compound feed and feed materials for food-producing animals containing L-valine, produced and labelled before 19 November 2026 under the old rules, can be placed on the market and used until stocks are exhausted.
* Compound feed and feed materials for non-food producing animals containing L-valine, produced and labelled before 19 November 2027, under the old rules, can be placed on the market and used until stocks are exhausted.
* **Entry into Force:** The regulation will enter into force twenty days after its publication in the Official Journal of the European Union.
* **Annex Provisions:**
* L-valine must have a minimum content of 98% on a dry matter basis.
* The directions for use of the additive and premixtures, the storage conditions and the stability to heat treatment must be indicated.
* Feed business operators shall ensure that L-valine is rumen protected, when fed to ruminants.
* The moisture content shall be indicated on the label of the additive.
* The label of the additive and premixtures shall indicate the following: "The supplementation with L-valine shall take into account all essential and conditionally essential amino acids in order to avoid imbalances.'
* End of period of authorisation: 19 November 2035.
**Impact Analysis**
**Stakeholder: Feed Business Operators**
* *Impact:* Need to comply with new requirements for L-valine production and labelling after the transitional periods. Must ensure L-valine is rumen protected when fed to ruminants and include specified details in directions for use and labeling.
* *Action Required:* Review and update production and labelling processes to align with the new regulations, particularly regarding rumen protection and amino acid balance.
**Stakeholder: Manufacturers of Compound Feed and Feed Materials**
* *Impact:* Need to comply with new requirements for L-valine content, production, and labelling after the transitional periods, depending on the intended animal use (food-producing vs. non-food-producing).
* *Action Required:* Review and update production and labelling processes to align with the new regulations, and ensure compliance with deadlines for the transitional periods.
**Stakeholder: Regulatory Authorities**
* *Impact:* Enforcement of the new regulation and monitoring compliance by feed business operators and manufacturers.
* *Action Required:* Update regulatory procedures and monitoring activities to reflect the new regulation and ensure compliance.

COMMISSION IMPLEMENTING REGULATION(EU) 2025/2183
of 29 October 2025
concerning the renewal of the authorisation of L-valine produced with Corynebacterium
glutamicumKCCM 80058 as a feed additive for all animal species and repealing Implementing
Regulation (EU) No 848/2014
(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 nutrition(1), 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 and renewing such an authorisation.
(2) L-valine produced with Corynebacterium glutamicumKCCM 80058 was authorised for a period of 10 years as a feed
additive for all animal species by Commission Implementing Regulation (EU) No 848/2014(2).
(3) In accordance with Article 14(1) of Regulation (EC) No 1831/2003, an application was submitted for the renewal of
the authorisation of L-valine produced with Corynebacterium glutamicumKCCM 80058 as a feed additive for all animal
species, requesting that additive to be classified in the category ‘nutritional additives’ and in the functional group
‘amino acids, their salts and analogues’. That application was accompanied by the particulars and documents
required under Article 14(2) of that Regulation.
(4) The European Food Safety Authority (‘the Authority’) concluded in its opinion of 28 January 2025(3)that the use of
L-valine produced with Corynebacterium glutamicumKCCM 80058 remains safe for all animal species, consumers and
the environment under the authorised conditions of use. The Authority also concluded that the additive is not an
irritant to skin or eyes nor a skin sensitiser. The Authority also indicated that there is no need for assessing the
efficacy of L-valine produced with Corynebacterium glutamicum KCCM 80058, as the application for renewal of the
authorisation does not include a proposal for amending or supplementing the conditions of the original
authorisation that would have an impact on the efficacy of the additive.
(5) The Reference Laboratory set up by Regulation (EC) No 1831/2003 considered that the conclusions and
recommendations reached in the assessment carried out regarding the method of analysis of L-valine produced with
Corynebacterium glutamicumKCCM 80058 as a feed additive in the context of the previous authorisation are valid and
applicable for the current application. In accordance with Article 5(4), point (c), of Commission Regulation (EC)
No 378/2005(4), an evaluation report of the Reference Laboratory is therefore not required.

(2) Commission Implementing Regulation (EU) No 848/2014 of 4 August 2014 concerning the authorisation of L-valine produced by
Corynebacterium glutamicum as a feed additive for all animal species and amending Regulation (EC) No 403/2009 as regards the
labelling of the feed additive L-valine (OJ L 232, 5.8.2014, p. 13, ELI: http://data.europa.eu/eli/reg_impl/2014/848/oj).

(4) Commission Regulation (EC) No 378/2005 of 4 March 2005 on detailed rules for the implementation of Regulation (EC)
No 1831/2003 of the European Parliament and of the Council as regards the duties and tasks of the Community Reference
Laboratory concerning applications for authorisations of feed additives (OJ L 59, 5.3.2005, p. 8, ELI: http://data.europa.eu/eli/reg/
2005/378/oj).

(6) In view of the above, the Commission considers that L-valine produced with Corynebacterium glutamicum KCCM
80058 satisfies the conditions, as provided for in Article 5 of Regulation (EC) No 1831/2003. Accordingly, the
authorisation of that additive should be renewed. It is appropriate that feed business operators ensure the protection
of L-valine from rumen degradation and that the label of the additive and premixtures indicates that the
supplementation with L-valine must take into account essential and conditionally essential amino acids in order to
avoid imbalances.
(7) As a consequence of the renewal of the authorisation of L-valine produced with Corynebacterium glutamicumKCCM
80058 as a feed additive, Implementing Regulation (EU) No 848/2014 should be repealed.
(8) Since safety reasons do not require the immediate application of the modifications to the conditions of authorisation
of L-valine produced with Corynebacterium glutamicum KCCM 80058, it is appropriate to provide for a transitional
period for interested parties to prepare themselves to meet the new requirements resulting from the renewal of the
authorisation.
(9) The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on
Plants, Animals, Food and Feed,
HAS ADOPTED THIS REGULATION:
