Tariffs

Overview

A tariff—a word derived from the Arabic "arafa," meaning "to make known"—is a tax imposed by a government on goods that are imported or exported.

Economically, tariffs aim to protect domestic industries, generate government revenue, and influence trade policy. Tariffs can be specific (a fixed fee per unit) or ad valorem (a percentage of the item's value).

Historically, tariffs have served as a primary source of revenue and a means to protect domestic industries, as they make foreign products more expensive—encouraging consumers to purchase locally produced goods. The tools have a checkered history, famously bolstering US textiles, German steel, Japanese cars, South Korean technology, and more, while arguably contributing to major economic downturns like the Great Depression.
