(2) The rules are that where—
(a)“SP1” is specified in column 6 of the DCTS Specified Goods Table, the DCTS rate is a nil rate;
(b)“SP2” is specified in column 6 of the DCTS Specified Goods Table, the DCTS rate is the standard rate of import duty, adjusted as follows—
(i)the by-value duty expression is reduced by 3.5 percentage points, in a case where that is the only duty expression representing the standard rate of import duty;
(ii)the specific duty expression is reduced by 30%, in a case where that is the only duty expression representing the standard rate of import duty;
(iii)the by-value duty expression is reduced in accordance with paragraph (i) and the specific duty expression is not reduced, in a case where the standard rate of import duty is represented by a compound duty expression;
(c)“SP3” is specified in column 6 of the DCTS Specified Goods Table, the DCTS rate is the standard rate of import duty, adjusted as follows—
(i)the by-value duty expression is reduced by 20%, in a case where that is the only duty expression representing the standard rate of import duty;
(ii)the by-value duty expression is reduced in accordance with paragraph (i) and the specific duty expression is not reduced, in a case where the standard rate of import duty is represented by a compound duty expression;
(d)“SP4” is specified in column 6 of the DCTS Specified Goods Table, the by-value duty expression used to calculate the standard rate of import duty is reduced to the by-value duty expression specified in column 7 of the DCTS Specified Goods Table.
(3) Whenever “SP2”, “SP3” or “SP4” is specified in column 6 of the DCTS Specified Goods Table—
(a)where the Tariff Table specifies a maximum import duty, that maximum duty is not reduced in respect of SP goods;
(b)where the Tariff Table specifies a minimum import duty, that minimum duty does not apply in respect of SP goods.
