4. 7. 81 Official Journal of the European Communities No L 183/1 (Acts whose publication is obligatory) COUNCIL REGULATION (EEC) No 1796/81 of 30 June 1981 on measures applicable to imports of preserved cultivated mushrooms THE COUNCIL OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, Having regard to Council Regulation (EEC) No 516/77 of 14 March 1977 on the common organiza- tion of the market in products processed from fruit and vegetables (1), as last amended by Regulation (EEC) No 1118/81 (3), and in particular Article 13 (2) thereof, Having regard to the proposal from the Commission, Whereas the prices at which preserved cultivated mushrooms are offered in the main supplier countries are substantially lower than the cost price of the Community industry and the quantities available in those countries are such that they are liable to disturb the Community market ; Whereas, confronted with this situation, the Commis- sion has, on several occasions since 1978, had to take protective measures with regard to imports of preserved cuitivated mushrooms ; Whereas it appears that this state of affairs is not likely to change in the near future and that the protec- tive measures which have been taken do not, in them- selves, constitute the most suitable means of reme- dying the situation; Whereas provision should therefore be made for measures of market management consisting in the levying of an additional amount on all imports into the Community exceeding the quantities traditionally traded ; Whereas in view of the characteristics of third coun- tries’ supplies to the Community, its market may be protected by fixing the additional amount at a level corresponding approximately to that of the costs of production in the Community ; (') OJ No L 73, 21. 3. 1977, p. 1. () O] No L 118, 30. 4. 1981, p. 10. Whereas, given the very small volume of imports of products originating in the Maghreb countries and the ACP States and the preferential treatment which the Community offers those countries and States, no addi- tional amount should be levied on those imports, HAS ADOPTED THIS REGULATION : Article 1 Every entry into free circulation in the Community of preserved  cultivated mushrooms falling  within subheading ex 20.02 A of the Common Customs Tariff, other than that referred to in Article 4, shall be subject to the levying of an additional amount for the quantity in excess of that laid down in Article 3. Article 2 1. The additional amount is hereby fixed at 160 ECU per 100 kilograms net. 2. This amount shall, as necessary, be adjusted in the light of the trend in the quantities imported in excess of the quantity laid down in Article 3 and of the trend in the production cost of Community products. Article 3 The quantity referred to in Article 1 shall be fixed at 34750 tonnes. It shall be allocated each year among the supplier countries, account being taken of tradi- tional Community trade flows and, in an appropriate manner, of any new suppliers. Article 4 All imports coming from Maghreb countries and from ACP States shall be exempt from the application of this Regulation on condition that the product origi- nates in the said countries or States and is accompa- nied by the movement certificate issued in accordance
