No L 56/12 Official Journal of the European Communities 29. 2. 92 COUNCIL REGULATION (EEC) No 521/92 of 27 February 1992 opening and providing for the administration of Community tariff quotas and ceilings for certain agricultural and industrial products originating in Hungary, Poland and the Czech and Slovak Federal Republic (CSFR) (1992) THE COUNCIL OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, and in particular Article 113 thereof, ' Having regard to the proposal from the Commission, Whereas the association agreements between the Euro- pean Economic Community and the Republic of Hungary, the Republic of Poland and the Czech and Slovak Federal Republic (CSFR) respectively were signed on 16 December 1991 ; whereas pending the entry into force of those agreements the Community has concluded - - interim agreements on trade and trade-related measures with those countries ; ’ Whereas the interim agreements stipulate, snter alia, that certain products originating in the countries in question may attract a reduced or zero rate of duty on import into the Community, within the limits of tariff quotas or ceilings; whereas pursuant to the provisions annexed to those agreements, the volumes of the tariff quotas and ceilings established when the association agreements were signed must be increased from the date on which the interim agreements enter into force by a percentage specific to each country and category of products ; whereas in accordance with Protocol 7 attached to each of those agreements, provision must furthermore be made for deduction of any quantities which have already benefited from generalized preferences between 1 January 1992 and the entry into force of those agree- ments and for pro rata adjustments to the quantities of the agricultural products listed in Annex II to this Regu- lation ; Whereas the quantities in question will be known only on the day preceding the entry into force of the interim agreements ; whereas the Commission should be made responsible for informing the Member States and economic operators as rapidly as possible of the quantities actually available under the tariff measures described in this Regulation by means of publication in the ‘C’ series of the Official Journal of the European Communities; Whereas it seems advisable in the interests of clarity to divide the products into two groups, in Annexes I and II to this Regulation, one for industrial products and one for agricultural products, specifying for each product the volume of its quota or ceiling and the rate of customs duty applicable ; Whereas under the tariff measures in question, Spain and Portugal will apply duties calculated in accordance with the provisions of their respective protocols, which are attached to the interim agreements ; Whereas in the case of the products listed in Annexes I and I to this Regulation which are subject to tariff quotas, particular care should be taken to ensure that all Community importers have equal and continuous access to those quotas and that the rates laid down for the quotas are applied to all imports of the products in question into all Member States until the quotas are exhausted ; whereas the necessary measures should be taken to provide for effective Community administration of the tariff quotas so that the Member States may draw against the tariff quotas * such quantities as they may need, corresponding to actual imports recorded ; whereas this method of administration requires close cooperation between the Member States and the Commission ; Whereas in the case of the products listed in Annexes I and II to this Regulation which are subject to Community tariff ceilings, Community surveillance may be achieved by means of an administrative procedure based on char- ging imports of the products in question against the ceilings at Community level as and when those products are entered with the customs authorities for free circula- tion ; Whereas this administrative procedure requires close and particularly rapid cooperation between the Member States and the Commission, and the latter must in particular be able to monitor 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 appropriate measures to reintroduce customs duties once a ceiling is reached; Whereas, since the Kingdom of Belgium, the Kingdom of the Netherlands and the Grand Duchy of Luxembourg are united within, and jointly represented by, the Benelux Economic Union, any operation concerning the adminis- tration of these tariff measures may be carried out by any one of its members,
