If Pakistan applies a tariff on ballpoint pens consisting of 25 rupees per pen plus 12% of the pen's price, what type of tariff is this an example of?

Explanation

A tariff that includes both a fixed fee per unit and a percentage of the item's value is known as a combined tariff, also referred to as a compound tariff. The other options describe tariffs that are either solely fixed (specific) or solely percentage-based (ad valorem), or a measure of tariff impact (effective tariff).
