After 450 amendments, the Tariff Act of 1890 was passed and increased average duties across all imports from 38% to 49.5%. McKinley was known as the "Napoleon of Protection", and rates were raised on some goods and lowered on others, always in an attempt to protect American manufacturing interests. Changes in duties for specific products such as tinplates and wool were the most controversial ones and were emblematic of the spirit of the Tariff of 1890. The Act eliminated tariffs altogether on certain items, with the threat of reinstatement as an enticement to get other countries to lower their tariffs on items imported from the US.
Eliminated tariffs The Act removed tariffs on sugar, molasses, tea, coffee, and hides but authorized the President to reinstate the tariffs if the items were exported from countries that treated U.S. exports in a "reciprocally unequal and unreasonable" fashion. The idea was "to secure reciprocal trade" by allowing the executive branch to use the threat of reimposing tariffs as a means to get other countries to lower their tariffs on U.S. exports. Although this delegation of power had the appearance of being an unconstitutional violation of the
nondelegation doctrine, it was upheld by the Supreme Court in
Field v. Clark in 1892, as authorizing the executive to act merely as an "agent" of Congress, rather than as a lawmaker itself. The President did not use the delegated power to re-impose tariffs on the five types of imported goods, but he used the threat of doing so to pass 10 treaties in which other countries reduced their tariffs on U.S. goods.
Tin-plates Tin-plates were a major import for the United States. Tens of millions of dollars in these goods entered the country each year. It also included a unique provision that stated tin-plates should be admitted free of any duty after 1897 unless domestic production in any year reached one-third of the imports in that year. The goal was for the duty to be protective or not to exist at all.
Wool The new tariff provisions for
wool and woolen goods were exceedingly protectionist. Wool was previously taxed based on a schedule: more valuable wool was taxed at a higher rate. Through a multitude of complicated tariff schedule revisions, the Act made almost all woolen goods subject to the maximum duty rate. The Act also increased the tariff on carpet wool, a wool of very low quality not produced in the US. The government wanted to ensure that importers were not declaring higher-quality wool as carpet wool to evade the tariff. ==Reactions==
