History of Tariffs
While import tariffs may seem unfamiliar due to historically low rates in recent decades, they have long played a significant role in U.S. economic policy-serving purposes such as revenue generation, industry support, and protectionism. Historically, high tariffs have often coincided with periods of economic and political instability, whereas lower tariffs have typically supported international engagement and economic growth. Since World War II and the creation of GATT and the WTO, the U.S. has generally maintained lower average tariff rates.
