As the United States Constitution specifically prohibits taxes on exports from the states, a tariff in -this- country only applies to foreign goods. There were -no- federal taxes in 1860.
You also conveniently ignore the fact that tariffs in 1860 were lower than they had been in 40 years.
Tariffs were not the cause of the war, slavery was.
