23.5.2007 Official Journal of the European Union L 1317 COMMISSION REGULATION (EC) No 551/2007 of 22 May 2007 amending and correcting Regulation (EC) No 952/2006 laying down detailed rules for the application of Council Regulation (EC) No 318/2006 as regards the management of the Community market in sugar and the quota system THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Community, Having regard to Council Regulation (EC) No 318/2006 of 20 February 2006 on the common organisation of the markets in the sugar sector (1), and in particular Article 40(1)(a), (b) and (d) thereof, Whereas: (1)  Article 6(3) of Commission Regulation (EC) No 952/2006 (%) defines the production of undertakings for the purposes of the common organisation of the markets in the sugar sector, in the particular case where one undertaking outsources production to another. This is deemed to be the production of the principal under certain conditions, including where the total sugar production of the processor and the principal is more than the sum of their quotas. This provision needs to be adapted in the light of Article 3 of Commission Regu- lation (EC) No 493/2006 of 27 March 2006 laying down transitional measures within the framework of the reform of the common organisation of the markets in the sugar sector, and amending Commission Regulations (EC) No 1265/2001 and (EC) No 314/2002 (}), which provides for a preventive withdrawal, applicable to the share of the production under quota which exceeds the threshold established in accordance with paragraph 2 of that Article. The aim of that measure is to create an incentive for sugar undertakings to reduce voluntarily their production in the marketing year 2006/07. It is also necessary to modify the definition of production in Article 6(3)(b) of Regulation (EC) No 952/2006 so that it does not discourage producers from reducing production. The definition of production for the marketing year 2006/07 should therefore concern the sum of the preventive withdrawal thresholds instead of the sum of quotas. 2)  Article 13(1) of Regulation (EC) No 952/2006 lays down that the obligation of undertakings to establish monthly () O] L 58, 28.2.2006, p. 1.

Regulation as last amended by Regu- lation (EC) No 119/2007 (OJ L 37, 9.2.2007, p. 3). prices concern quota sugar and non-quota sugar re- spectively. However, this distinction is not relevant for refiners, since their activity, which consists of refining imported sugar, is not dependent on the allocation of quotas. The fact that the distinction between quota and non-quota sugar does not apply to them needs to be explicitly indicated, so as to avoid confusion. (3)  For sugar for industrial uses, the price reporting system established in accordance with Article 4 of Regulation (EC) No 318/2006 should focus on transactions of a minimum volume, since there is little interest in estab- lishing a price indicator with regard to transactions where the quantities are insignificant. It is therefore appropriate to fix a minimum threshold for the appli- cation of the requirement to establish and communicate to the Commission the monthly average of purchase prices. (4 The application of the transitional provisions on trans- mission of price data to the Commission laid down in Article 15 of Regulation (EC) No 952/2006 needs to be extended until the first quarter of 2008 to allow for the drawing up of a report on the operation of the system followed by the implementation of a computerised system. (5)  The one-off amounts to be paid for additional sugar quotas and for supplementary isoglucose quotas pursuant to Articles 8(3) and 9(3) of Regulation (EC) No 318/2006 are part of the Communities own resources pursuant to Article 2(1)@@ of Council Decision 2000/597/EC, Euratom of 29 September 2000 on the system of the European Communities’ own resources (*). The date of notification of these amounts to the debtor should be fixed, in order to determine the date of establishment of the Community’s entitlement in accordance with the second subparagraph of Article 2(2) of Council Regulation (EC, Euratom) No 1150/2000 of 22 May 2000 implementing Decision 94/728/EC, Euratom on the system of the Communities’ own resources (°).
