After months of debate, Congress produced a bill that raised the average import duties on agricultural products from 38 percent to 49 percent and average import duties on industrial products from 31 percent to 34 percent. In June 1930, over the objection of many economists, Congress approved and Hoover reluctantly signed into law the Smoot–Hawley Tariff Act. The intent of the act was to encourage the purchase of American-made products by increasing the cost of imported goods, while raising revenue for the federal government and protecting farmers.
