What Tariff led to retaliatory tariffs in countries?

The Smoot-Hawley Tariff Act of 1930 led to widespread retaliatory tariffs from other countries. This U.S. legislation raised duties on many imports, prompting trading partners to impose their own tariffs in response. The resulting trade barriers contributed to a decline in international trade and worsened the Great Depression. Many economists consider this act a significant misstep in U.S. trade policy.
