Tariffs are taxes on imported goods. Understanding how they work, who pays them, and what they actually accomplish is essential context for understanding trade policy.

A tariff is a tax imposed on imported goods at the border. The government imposing the tariff collects revenue; the question of who actually bears the cost is the central economic debate about tariff policy — and the answer is more politically inconvenient than most tariff advocates acknowledge.
When the U.S. government imposes a 25% tariff on imported washing machines from South Korea, a washing machine that previously cost $500 lands at the border with an additional $125 tax. The foreign manufacturer can absorb some of this through lower margins, but in competitive markets they cannot absorb all of it. The result: the price of the washing machine rises in the U.S. market, and American consumers pay more — either for the imported washing machine at the higher tariffed price, or for a domestic alternative whose manufacturer has used the tariff as an umbrella to raise their own price. The 2018 washing machine tariffs are well-studied; economists found that prices rose by approximately $86 per unit for American consumers.
The political logic of tariffs is straightforward: they protect domestic industries and jobs from foreign competition. If American steel is priced out of the market by cheaper Chinese or South Korean steel, American steelworkers lose jobs. A tariff on imported steel raises its price, making American steel more competitive, potentially saving those jobs.
The economic reality is more complex. Tariffs on inputs (like steel) raise costs for industries that use those inputs (like auto manufacturing, construction, appliance makers). The Peterson Institute estimated that the 2018 U.S. steel tariffs saved approximately 8,700 steelworker jobs while costing approximately 75,000 jobs in steel-consuming industries. The protected jobs are visible and concentrated; the lost jobs are dispersed and less politically salient. Politicians who impose tariffs can point to the steelworkers they saved; the auto workers whose plant closed due to higher steel costs don't generate the same headline.
Tariffs also invite retaliation. When the U.S. imposed tariffs on Chinese goods in 2018, China retaliated with tariffs on American agricultural exports — soybeans, pork, corn. American farmers, who had nothing to do with the trade disputes that prompted the original tariffs, lost significant export market access. The U.S. government then paid approximately $28 billion in farm subsidies to compensate farmers for the losses caused by its own trade policy.
Not all tariff arguments are purely about protecting domestic employment. Tariffs are also used as:
National security tools: Maintaining domestic capacity in industries deemed strategically essential — semiconductors, pharmaceutical ingredients, defense components — is a legitimate argument for tariffs or subsidies even if the protected industry is less efficient than foreign alternatives. Depending entirely on a potential adversary for critical supply chains creates vulnerability.
Leverage in trade negotiations: Tariffs imposed or threatened as negotiating leverage can extract concessions from trading partners. The effectiveness depends on whether the threatened party believes the tariffs will actually be imposed and maintained, and whether they have retaliatory options.
Revenue generation: Historically, before income taxes, tariffs were a primary source of government revenue. In the modern U.S. context, tariff revenue is modest relative to total federal revenue — the 2018-2019 tariff increases generated roughly $70-80 billion annually, against a $4.5 trillion federal budget.
For individual consumers, tariffs function as a price increase on affected goods — a tax whose incidence falls primarily on buyers rather than foreign sellers. The categories where tariff effects are most visible in consumer budgets:
Clothing and footwear: Most of the U.S. tariff schedule's highest rates apply to these categories — some tariff rates on imported clothing exceed 30%. American consumers pay more for clothing partly because of decades of protective tariffs.
Electronics: The 2018-2019 tariffs on Chinese goods covered many consumer electronics components. Some manufacturers absorbed costs; some passed them through. The cumulative effect on electronics prices was measurable.
Autos and auto parts: Tariffs on imported steel and aluminum raised vehicle manufacturing costs, contributing to higher new vehicle prices alongside other factors.
The practical implication: tariff policy is fiscal policy with a different name. When tariffs rise, prices rise, and consumers pay more. Whether the jobs protected or strategic objectives achieved justify that cost is a policy question with no purely technical answer. See how trade deficits work and impact of exchange rates.
