s 29A Reduced rate
(1) VAT charged on— (a) any supply that is of a description for the time being specified in Schedule 7A, or (b) any equivalent ... importation, shall be charged at the rate of 5 per cent. (2) The reference in subsection (1) to an equivalent importation, in relation to any supply that is of a description for the time being specified in Schedule 7A, is a reference to any importation of any goods the supply of which would be such a supply. (3) The Treasury may by order vary Schedule 7A by adding to or deleting from it any description of supply or by varying any description of supply for the time being specified in it. (4) The power to vary Schedule 7A conferred by subsection (3) above may be exercised so as to describe a supply of goods or services by reference to matters unrelated to the characteristics of the goods or services themselves. In the case of a supply of goods, those matters include, in particular, the use that has been made of the goods.
