Commission Regulation (EC) No. 1799/2001 laying down the marketing standard for citrus fruit.

The marketing standards for oranges, mandarins (including tangerines and satsumas), clementines, wilkings and similar citrus hybrids, as well as lemons, shall be as set out in the Annex to the present Regulation. These marketing standards must be applied at all stages of marketing. However, at stages following dispatch, the products may show in relation to the provisions of the standard a slight lack of freshness and turgidity and, as regards products graded in classes other than the "Extra" class, slight deteriorations due to their development and their tendency to perish. The standards regard in particular size, presentation, packaging, tolerances and marking.
