24. As far as the applicability of exclusion (b) of the General Explanatory Note to Chapter 4 is concerned, the Secretariat wishes to note that the addition of vegetable oil to a product containing milk fat will inevitably result in a product containing vegetable oil and a lower proportion of other fats in a given quantity of the final product compared to the balance of these ingredients before vegetable oil was added. In other words, oleic fats will simply crowd out the butyric fats and therefore, arguably, replace them. From this perspective, it can be assumed that the addition of vegetable oil to a product containing milk fat in all circumstances leads to a replacement of milk fat with vegetable oil, and thus a replacement of butyric fats by oleic fats, at least to a certain extent.
