In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Dow AgroSciences submitted a request to the competent national authority in Finland, to set an import tolerance for quizalofop-P-ethyl in grain from genetically modified maize containing aad-1 gene. The data submitted in support of the request were found to be sufficient to derive a maximum residue level (MRL) proposal for quizalofop-P-ethyl maize grain. Adequate analytical methods for enforcement are available to control the residues of quizalofop-P-ethyl in maize grain. Based on the risk assessment results, EFSA concluded that the authorised use of quizalofop-P-ethyl on genetically modified maize containing aad-1 gene and the subsequent import of maize grain in Europe will not result in a consumer exposure exceeding the toxicological reference value and therefore is unlikely to pose a risk to consumers' health.
