Editing Walker tariff (section)

==Adoption==
Democrat [[James Polk]] was [[1844 United States presidential election|elected President in 1844]] over [[Henry Clay]], a [[Whig Party (United States)|Whig]] who advocated a high tariff.

[[President of the United States|President]] Polk declared that reduction of the "Black Tariff" would be the first of the "four great measures" that would define his administration. He directed Walker to work out the details. In 1846, Polk delivered Walker's tariff proposal to [[United States Congress|Congress]]. Walker urged its adoption to increase commerce between the US and Britain. He also predicted that a reduction in tariff rates would stimulate trade, including imports. The result, asserted Walker, would be a net increase in customs revenue, despite the reduced rates.

Congress, then controlled by Democrats, acted quickly on Walker's recommendations. Southern Democrats, who had little industry in their states, were especially supportive.

The Walker Tariff produced the nation's first standardized tariff: rather than setting fixed rates for specific items on a case-by-case basis, it established general schedules into which all goods could be classified, subject to defined [[ad valorem]] rates. The bill reduced rates across the board on most major import items save [[luxury goods]], such as [[tobacco]] and [[alcoholic beverage]]s.
