A tariff is a tax on goods from other countries. The U.S. government charges it at the border.

What it is

A tariff is a tax on imports -- goods made in other countries. "Buy American" and "protectionism" both mean using tariffs and rules to help U.S.-made goods beat foreign ones: when a product crosses the border, a U.S. business pays the tax, and that extra cost is often passed on to shoppers. Many studies of the 2018-2019 and 2025 tariffs found the same thing: American firms and shoppers, not foreign sellers, paid almost the whole cost. One Federal Reserve estimate put about 90 percent of the cost on U.S. firms and buyers. Jobs are more mixed. A protected industry like steel can add some jobs, but parts cost more and other countries hit back with tariffs of their own -- and on balance, studies of the 2018-2019 tariffs found they cost more factory jobs than they saved. These cost findings are widely accepted; the real fight is about the future. Is the long-run payoff -- more factories, more things made at home, and national security -- worth paying more today?

How it works

A tariff is charged at the border, usually as a percent of a product's price -- the U.S. business bringing the goods in pays it, not the foreign country. Tariffs can be broad, covering almost everything, or targeted: some hit one product, like steel, others hit one country, like China. Two common legal tools have names: "Section 232" is used for national security, and "Section 301" is used against unfair trade. When the U.S. adds tariffs, other countries often hit back -- this is called retaliation, and it makes U.S. exports harder to sell abroad. "Buy American" rules go further, telling the government itself to buy U.S.-made goods. In 2025, U.S. tariffs rose sharply, and the average tariff rate hit its highest level since 1947. People debate tariffs because they pull two ways at once: they can protect some U.S. factories and jobs, but they can also raise prices and invite payback that hurts farmers and exporters. California feels both sides. It has big factories and busy ports, but it also has huge farm exports, like almonds and wine -- and other countries can tax those exports in return.

The debate — equal weight, both sides

The case for protecting industry with tariffs

Cross-cutting. It is made most by pro-factory populists and security-minded conservatives. Some labor unions and steel and factory workers back it too. They want to protect U.S. jobs.

Some things matter more than the lowest price. A country that cannot make its own steel, medicine, or weapons is not truly safe -- as one supporter puts it, "you actually have to make things." The COVID crisis proved the point: masks, ventilators, and drug ingredients ran short because factories had moved overseas. Tariffs push money back home by making imported goods cost more, so companies build and hire in the U.S. instead. Factory jobs are special, backers say: each new factory job supports 5 to 7 more jobs in nearby suppliers and shops. After the 2018 steel tariffs, steel and iron mill jobs rose by 1,600 in 2018 and 3,200 more in 2019. Supporters also see tariffs as fixing an unfair game -- other countries help their own industries and block our goods, and a tariff just levels the field. One model of a 10 percent tariff on all imports predicts 3.3 million new jobs and higher family incomes over time. To this camp, a little more paid at the store buys strong factories, good jobs, and a safer country.

The case for free trade (tariffs are a tax)

Cross-cutting. It is made most by free-market conservatives and libertarians. Most mainstream economists share it too. So do consumer and farm-export groups. They fear higher prices and payback from other countries.

Trade is just people buying what they want at the best price, and a tariff is a tax that Americans pay. The Tax Foundation found the 2025 tariffs cost the average U.S. household about $1,000 in one year -- money families cannot spend on rent, food, or savings. Free trade lowers prices and gives shoppers more choices; protectionism does the opposite, and it costs a lot. The Cato Institute looked at older U.S. trade barriers and estimates they cost about $620,000 a year for each job they saved. Tariffs also start fights: when the U.S. taxes imports, other countries tax our exports back. California almond growers learned this the hard way -- after the 2018 tariffs, their price fell from $2.50 a pound to $1.40. In a survey of top economists on steel and aluminum tariffs, none said they would make Americans better off. To this camp, tariffs help a few loud industries while taxing everyone else -- a bad deal that raises prices and picks winners for political reasons.
