Thanks for your response and the information on U. S. tariffs.
However, that does nothing to answer the question I posed: "Were retaliatory tariffs even considered by our antebellum trading partners?" Specifically: did Britain or France consider retaliatory tariffs on imports from the United States?
"Cotton growers in the South exported raw cotton to Britain, and they were opposed to any tariff that would restrict the sales of their British customers to the United States. They worried about both loss of sales and further losses due to possible British retaliation."
