What Are Tariffs?

Tariffs are taxes that governments impose on trade. While they can apply to exports, they are primarily levied on imports, typically to protect local industries. Imagine a local market selling apples. The retailer can choose between locally grown apples and imported ones. If a foreign producer wants to sell apples in this market, they might find their goods subject to a tax a tariff making imported apples more expensive than domestic ones.
The rationale behind tariffs is straightforward:

• By making imports more expensive, tariffs make local goods comparatively cheaper and, at least in the short run, more competitive.
• Like other taxes, tariffs provide income that can be used to support local industries, fund public programs, or cover government expenditures.
• Tariffs can serve as bargaining tools to extract concessions from trading partners.

On February 2, 2025, President Trump signed an executive order imposing a 25 percent tariff on all goods imported from Mexico and Canada, with a 10 percent tariff on Canadian oil. These measures targeted the United States’ two largest trading partners under the US-Mexico-Canada Agreement (USMCA). A crisis was temporarily averted when the White House later suspended the tariffs after striking last-minute deals from Mexico and Canada to secure their borders. This decision prevented, at least for now, a damaging trade war that could have disrupted North America’s economy and sent shockwaves through global markets.
