The rules on labelling laid down by Regulation (EC) No 767/2009 will have to be applied as from 1 September 2010. This would imply an abrupt change and not allow a smooth transition for the feed business operators placing feed on the market. Switching the design and production of labels and the conversion of the existing machinery from one day to the other would be expensive for those businesses. The resulting burden would be disproportionate to the objective of the change.
It is therefore appropriate to provide for a transitional period during which feed may be labelled in accordance with Regulation (EC) No 767/2009 before 1 September 2010.
