Consequently the abovementioned tariff benefit does not apply in Spain and Portugal. Whereas the application of ceilings requires the Commu- nity to be regularly informed of the trend of imports of the relevant products originating in these countries; whereas imports should, therefore, be made subject to a system of surveillance ; Whereas this objective may be achieved by means of an . administrative procedure based on offsetting imports of the products in question against the ceilings at Commu- nity level as and when these products are entered with customs authorities for free circulation; whereas this administrative procedure must make provision for the possible re-establishment of customs tariff duties as soon as the ceilings are reached at Community level ; Whereas this administrative procedure requires close and particularly swift cooperation between the Member States and the Commission ; whereas the latter must, in parti- cular, be able to follow the progress of quantities charged against the ceilings and keep the Member States informed ; whereas this cooperation has to be particularly close since the Commission must be able to take the appropriate measures to re-establish customs tariff duties if one of the ceilings is reached; Whereas the measures provided for in this Regulation are in accordance with the opinion of the Management Committee for Fruit and Vegetables, HAS ADOPTED THIS REGULATION : Article 1 1. Imports of the products, originating in the African, Caribbean and Pacific States, and the overseas countries and territories, which are listed in the Annex, shall in the Community as constituted at 31 December. 1985, be subject to ceilings and to Community surveillance. The products referred to in the first subparagraph, their tariff headings, the customs duties applicable, the periods of validity and the levels of the ceilings are set out in the said Annex.
