Article 5
1. Subject to the conditions set out in this Regulation, the Member States shall allow suppliers to place on the market seed authorised in accordance with Article 3. They may require suppliers to seek permission in advance, which may be refused if: (a) there is sufficient evidence to doubt whether the supplier is able to place on the market the amount of seed for which he has sought permission; or (b) the total quantity for which the supplier seeks permission pursuant to the derogation concerned would exhaust the maximum quantity authorised for the Community under Article 2. 2. The requesting Member State shall coordinate the work of the other Member States in order to ensure that the total amount authorised is not exceeded. 3. The Member States shall assist each other administratively in the application of this Regulation. They shall inform the Commission and the other Member States of the contact points referred to in Article 2(1) within one month of entry into force of this Regulation.
