Lisa, In my experience, the only way you can get away with the "ferrite required" statement is to either provide the cable with a ferrite installed or to provide the ferrite itself. Ferrites are considered not commonly available items (by the FCC for example) and so therefore must be provided by you the vendor. Much better is to provide the cable with a ferrite molded in place, although snap-on ferrites have become acceptable. You will also need to add a statement to the user/installation manual that specifies the use of the supplied ferrite/cable.

If you have a product that, at one particular frequency during radiated RF, you simply cannot get to pass the requirements of the relative CE standard without putting an external ferrite on the cable, is it "legal" , to still mark it, provided you inform your customers via the declaration of conformity or in the manual etc., that they could experience problems at such and such frequencies and if they do, to use a ferrite? (boy, that was a mouthful). Faced with a redesign or a statement, the words would be the easier route to take, since in this case, the customer could probably never see the problem frequency range.
