Non,
You said a tariff was not a tax and it is. There are domestic and foreign tariffs. A domestic one (as was the case with the Whiskey Rebellion) is sometimes called an excise tax, which often referred to as a tariff.
But the larger point is this my friend, it's a tax, no two ways about it. It's the govt in the pockets of someone. You can mince words and call it a "duty" or whatever, but it's a tax pure and simple.
Did you not read the definition you posted from Wikipedia? "A tariff is a tax on foreign goods." It says nothing about domestic tariffs and foreign tariffs. At any rate a domestic tariff would be unconstitutional, per Article I, Section 9, Clause 5 and 6 wouldn't it?
