American
Tariff History
From the founding revenue system to Smoot-Hawley, reciprocal trade, Section 232, Section 301, IEEPA, and the modern refund era. Follow the statutes, government actions, court decisions, and economic record that shaped American tariff power.
Tariffs are as old as the federal government.
American tariff policy is not one continuous doctrine. It is a recurring argument over revenue, protection, trade policy, congressional power, presidential authority, economic pressure, retaliation, and international negotiation.
This collection organizes that history around the primary sources that created it: statutes, presidential actions, agency findings, trade agreements, government reports, litigation, and economic data.
