Walker tariff

The Walker Tariff was a set of tariff rates adopted by the United States in 1846. Enacted by the Democrats, it made substantial cuts in the high rates of the "Black Tariff" of 1842, enacted by the Whigs. It was based on a report by Secretary of the Treasury Robert J. Walker.

The Walker Tariff reduced tariff rates from 32% to 25%. Coinciding with the United Kingdom of Great Britain and Ireland's repeal of the Corn Laws, it led to an increase in trade. The tariff still remained higher than the 20% universal tariff that existed before the Tyler tariffs were imposed.
