Informopedia Explains: tariffs are the most argued-about tax in the world, and also the most misunderstood. Ask who pays them and you will hear, with total confidence, that the foreign country pays. That is wrong. The answer is written into American law, and it has been tested by economists using millions of real shipment records. It is also the reason your coffee, your phone and your car all got more expensive in the last two years.
A tax at the border
A tariff is simply a tax on imported goods, collected at the border by the government of the country doing the importing. In the United States, the law is unambiguous: the “importer of record” — the American company that brings the goods in, or the licensed customs broker acting for it — owes every dollar of duty to US Customs and Border Protection when the goods cross the border. The foreign manufacturer owes nothing. The foreign government owes nothing. No cheque ever travels from Beijing or Berlin to the US Treasury.
The importer files entry paperwork declaring the value of the goods, their classification under the Harmonized Tariff Schedule, and the applicable duty rate. A 25% tariff on a $100 shipment means $25 paid to Customs before the goods clear the port. The system is old — tariffs were the US federal government’s main source of revenue in the 19th century — and the mechanics have not changed. What has changed is the scale.
Who ends up poorer
Legally, the importer pays. Economically, the question is who ends up poorer once prices adjust — and here the evidence is strikingly consistent. In January 2026, the Kiel Institute for the World Economy analysed more than 25 million individual shipment records covering nearly $4 trillion of US imports. It found that 96% of the tariff burden fell on American importers and consumers, and foreign exporters absorbed just 4%. The roughly $200 billion rise in US customs revenue in 2025, the researchers wrote, was not wealth extracted from foreign producers. It was a transfer from American households and businesses to the Treasury — a consumption tax on imported goods.
The reason is simple: the importer treats the tariff as a cost, like freight or raw materials, and passes it on. The distributor raises its price, the retailer raises its price, and the shopper pays more. The pass-through is often amplified by markups along the chain — a 25% tariff on a $100 item does not just add $25 to the retail price, because if the retailer marks up by 50%, the tariff adds $37.50 to the final price. And because the cost is baked into the price rather than listed on the receipt, most shoppers never see it.
There are exceptions. Sometimes a foreign exporter cuts its price to stay competitive, absorbing part of the tariff. Sometimes a big importer squeezes its supplier instead of raising prices. But five independent studies using different methods have now converged on the same finding: the buyers in the importing country bear nearly the whole tariff. The side of the market that is less able to walk away pays the most — and in the world’s biggest consumer market, that is usually the buyer.
Why governments do it anyway
If tariffs mostly tax your own citizens, why impose them? Because they do three things at once, and governments value all three. First, they protect domestic producers: a tariff makes the foreign competitor’s product more expensive, giving the local factory room to compete. Second, they raise revenue — in 2025 the US federal government collected roughly $287 billion in customs duties, taxes and fees, a 192% increase on the year before. Third, they are leverage: a tariff is a threat that can be traded away in negotiations, which is how China agreed to halve its hybrid car exports to Europe after crunch talks in Beijing, and how the US president waived a sanctions bill that would have imposed tariffs of up to 100% on India and China just a day before it bit.
The costs are real, too. The Smoot-Hawley Tariff Act of 1930, which raised US duties on thousands of goods, is widely blamed for deepening the Great Depression by collapsing world trade — trading partners retaliated, American exports fell, and everyone ended up poorer. That lesson shaped the post-war system: the GATT, and later the World Trade Organization, spent seventy years pushing average tariffs down. The average effective US tariff rate reached 7.7% in 2025, the highest since 1947 — a reminder of how far the pendulum has swung back.
What to watch
Tariffs work like a tax, feel like a price rise, and act like a negotiating weapon — all at the same time, which is why the argument about them never ends. The next time you hear that a foreign country is “paying” a tariff, ask the follow-up question: paying whom? The money goes from an American importer to the American Treasury, and from there, eventually, out of American pockets. The foreign country pays only in lost sales — which is a real cost, but a very different one from the cheque that never arrives.
