A tariff is a tariff is a tariff, no matter what you name it.
True, but what's the goal? A protective tariff is used to cause the import's price to be higher than the domestic item's price so that people will buy products made in their own country.
A revenue tariff is an excise used to raise revenue only. The products taxed would be chosen to generate the most revenue with the least harm.
of course, these can be combined. But a protectived tariff is generally much higher, such as the 100 percent tariff that Reagan put on Japanese motorcycles to protect Harley Davidson.
