Article 3
1. The excise duty levied by Member States on beer shall be fixed by reference either: - to the number of hectolitre/degrees Plato, or - to the number of hectolitre/degrees of actual alcoholic strength by volume of finished product. 2. In assessing the charge to duty on beer in accordance with the requirements of Directive 92/84/EEC, Member States may ignore fractions of a degree Plato or degree of actual alcoholic strength by volume. In addition, Member States which levy the duty by reference to the number of hectolitre/degrees Plato may divide beer into categories consisting of no more than four degrees Plato per category and charge the same rate of duty per hectolitre on all beers falling within each category. Such rates shall invariably equal or exceed the minimum rate laid down in Article 6 of Directive 92/84/EEC, hereinafter referred to as the minimum rate.
