The collective mark of agri-food co-operatives’ products of SUDOE is a document that analyses the potential of a future collective brand for the products of European co-operatives: name, general aspects and attributes of the products about customer criteria, technical requirements, control system, etc. It is by no means certification in the strict sense of the word but is only intended as a simple guide to be analysed shortly, perhaps in another Interreg Sudoe project.
