What happens if an unauthorized active substance or an exceedance of the maximum residue level is detected in a sample?

QS continuously checks compliance with the maximum residue levels and the approval of the detected active substances for the respective product in the country of origin. If it is determined that the maximum residue level has been exceeded or a not authorised active substance has been detected, the location of the producer is blocked by QS for the delivery of the respective product into the QS scheme. The location can be unblocked as soon as QS has received an analysis report without compliant.
