Does anyone know if it is compulsory in Switzerland to state whether vegetable oil is present as hydrogenated fats? In other words, does the manufacturer have to state its fats are gehaertet (transfats) if they are, or can they get away with saying just vegetable oil?

I have a feeling it is compulsory, but would like to be sure. Today I saw 'palm oel, gedaempft, which sounds very suspicious to me.
