tariff tax of 1846 (which lasted thru 1857) put a 25 percent tax on exported cotton...schedule C. there is 500 pounds per bale of cotton. cotton sold for 10 to 12.5 cent per pound. let's round down (to give benefit of doubt) to 50 dollars per bale. Roughly 3 to 4 million bales were exported per year in the years leading up to the Civil war. 50 dollars per bale times 3 to 4 million bales exported equals roughly 200 million dollars exported per year 25% duty or tax on that between 1846/57 or 24 percent from 1858/60 is roughly rounded down (again for the benefit of doubt) to 40 million of the 53 million the federal government took in in taxes.....just in slave labor cotton alone....mind you...not any other southern export..
"The Tariff of 1828 was a protective tariff passed by the Congress of the United States on May 19, 1828, designed to protect industry in the Northern United States. Created during the presidency of John Quincy Adams and enacted during the presidency of Andrew Jackson, it was labeled the "Tariff of Abominations" by its Southern detractors because of the effects it had on the Southern economy. It set a 38% tax on 92% of all imported goods and a 45% tax on raw materials, such as tobacco and cotton, two of the South's strongest commodity" () and was replaced with the Walker tariff that replaced taxes with ad valorem duties and dropped the 45% tax on cotton to 25%. It appears that the 25% levied on cotton via the act of 1846 is not in fact an "export tax" "duty" out of the USA but rather to northern states in the form of "ad valorem duties".
This seems wrong to me. The tariff acts of the United States placed duties on Imports.
