The maximum residue limit (MRL) is the highest concentration of residue accepted by the European Union (EU) in a food product obtained from an animal that has received a veterinary medicine. 

Applicants need to submit an application to EMA for:

  • establishing an MRL for a new pharmacologically active substance;
  • extending an existing MRL to a new animal species.

EMA charges a fee for MRL applications.

It may grant a total or partial fee exemption for veterinary medicinal products classified as eligible for authorisation according to Article 23 of Regulation (EU) 2019/6, i.e. applications for limited markets.

For more information, see:

Pre-submission guidance

Applicants must submit the MRL application at least 6 months before the marketing authorisation application.

At least 6 months before the intended submission of the MRL application, applicants need to submit an MRL letter of intent via the Iris Portal with the following:

  • Name of the substance
  • Intended use (indication)
  • Target species
  • Intended target submission date

If the company has a valid micro, small and medium-sized enterprise (SME) status or a classification as eligible for authorisation according to Article 23 of Regulation (EU) 2019/6, they should include this information in the notification.

The data requirements and dossier structure are laid down in the Commission Implementing Regulation (EU) 2017/12.
