The main activity of a producer organisation shall relate to the concentration of supply and the placing on the market of the products of its members for which it is recognised.

The value of the marketed production of the producer organisation's own members and of members of other producer organisations that it sells, shall be more than the value of all the other marketed production which it sells.

This calculation shall be based only on products for which the producer organisation is recognised.

Where Article 52(7) applies, paragraph 2 of this Article shall apply mutatis mutandis to the subsidiaries concerned from 1 January 2012.
