Notwithstanding the rules on the interpretation of the Combined Nomenclature, the wording of the description of products must be regarded as merely indicative, since the applicability of the preferential arrangements is determined, within the context of this Annex, by the scope of the CN codes. Where ‘ex’ CN codes are indicated, the application of the preferential scheme is to be determined on the basis of the CN code, TARIC codes (if any) and corresponding description taken together.
