Why did the south oppose to high tariffs?

The reason is because they were really big farmers and want to get supplies cheap for example a farmer before the tariff could by a wheel from the british for maybe 1 dollar and the U.S sells it for $1.50 but with the tariff the wheel from the british would be 2 dollars and the u.s would still be $1.50. So I guess you could say they didn't like it because of farming supply prices.
