(10)As regards nicotine, by Regulation (EU) No 812/2011note provisional MRLs were set for tea, herbal infusions, spices, rose hips and fresh herbs until 14 August 2013, pending the submission and evaluation of new data and information on the natural occurrence or formation of nicotine in the concerned products. The Commission was informed of a research project which is being carried out to investigate on the sources of nicotine resulting in those crops. In view of the expected duration of the study and in order to provide the necessary time for the Commission to take its decision, it is appropriate to extend the validity of these MRLs until three years from the publication of this Regulation.
