If, during official inspections referred to in Article 12, or the trials referred to in Article 14, it is found that propagating material does not meet the requirements of this Directive, the responsible official body shall ensure that the supplier takes appropriate corrective action or, if that is not possible, shall prohibit the marketing of that propagating material in the Community.

If it is found that propagating material marketed by a particular supplier does not comply with the requirements of this Directive, the Member State concerned shall ensure that appropriate measures are taken in relation to that supplier.

Any measures taken under paragraph 2 shall be withdrawn as soon as it has been established with sufficient certainty that the propagating material intended for marketing by the supplier will, in future, comply with the requirements and conditions of this Directive.
