In 1860, they "imported" a total of $237M worth of goods into the Confederate states. Of course the word "import" must be modified here to say that $200M of that was inter-state trade from the North with only $37M being from the rest of the world. I'll have to look up the other end of the deal -- i.e. how much cotton, sugar and tobacco Northern states bought from the south, but with twice the population it's easy to assume that the North bought at least twice that $200M amount from the south. The South had to have a positive balance of trade with the North.
Those imports to the future confederate states included: $42M of woven cotton goods ($27M from Northern states & $15M from other countries)
$3M worth of Sugar (none from the north)
and $2M worth of Cigars --- all from foreign sources. (Cubans made damn fine cigars even back then.)
So of their total foreign imports in the year 1860 of $37M which were subject to US tariffs, 54% consisted of Cotton goods, sugar and cigars.
LOL. So you would have us think they were willing to go to war about tariffs they were paying on things they grew at home.
The damn war wasn't about tariffs GOP ---- It was all about slavery!
