In 60 seconds: A tariff is a tax on imported goods — and it's not the foreign country that pays it. The US importer writes the check to Customs at the border, and research shows 60–70% of that cost ends up in American prices within months. Here's how the whole machine actually works, and how to read the tariff headlines flying around this week.
- Tariffs are paid by the US importer of record to Customs and Border Protection — foreign exporters never touch the money.
- Federal Reserve research on the 2018–19 tariffs found roughly 60–70% of the duty showed up in higher US consumer prices within six months.
- The US collected about $287 billion in customs duties in fiscal 2025, up 192% from the prior year — nearly all of it from domestic pockets.
- Tariff costs arrive at the checkout with a lag of several months, so today's headlines are tomorrow's prices.
- This week's Graham Act waiver is a live example: 100% tariffs on Russian-oil buyers were hours from taking effect when Trump froze them.
Here's a question that trips up almost everyone: when the US slaps a tariff on Chinese goods, who actually pays? If you answered "China," you're in good company — and you're wrong. Not morally wrong, just mechanically wrong. The answer is sitting in your grocery bill, your electricity-adjacent everything, and a little-known office called the importer of record. Let's pull the whole thing apart.
What a tariff actually is
A tariff is simply a tax charged on goods entering the United States from another country. That's it. It's calculated from the Harmonized Tariff Schedule — a giant official catalog that assigns a duty rate to every product imaginable, based on what it is, where it was made, and what it's worth. Rates come in two flavors: ad valorem (a percentage of the value, like 25%) and specific (a fixed amount per unit, like $2 per kilogram). When people say "a 100% tariff on Russian oil," they mean the tax equals the full value of the oil itself — the price effectively doubles at the border.
So who writes the check?
This is the part that surprises people. Under US law, the tariff is paid by the importer of record — the US company (or its licensed customs broker) that files the entry paperwork. In more than 95% of cases, that's an American entity: a retailer, a manufacturer, a distributor. The payment goes to US Customs and Border Protection at the port of entry, usually within 10 business days, secured by a customs bond.
The foreign exporter? They ship the goods, get paid, and never touch the duty money. The foreign government? Not involved at all. Every dollar of the roughly $287 billion in customs duties collected in fiscal 2025 — a 192% jump from the prior year — came out of a US importer's account. "Foreign countries pay tariffs" is political shorthand. Mechanically, it's not how any of this works.
But who really pays? Follow the money.
Here's where it gets interesting, because the legal payer and the economic payer aren't the same. Once the importer pays CBP, the cost splits three ways:
Scenario one: the importer absorbs it. Thin-margin retailers with long supplier contracts eat some or all of the tariff to keep shelf prices steady. Their profits take the hit instead of your wallet — for a while.
Scenario two: the foreign supplier discounts. Big American buyers with alternatives — Vietnam, Mexico, India — lean on suppliers to cut prices 3–8% to keep the order. The exporter bleeds a little to stay in the game.
Scenario three: you pay. In competitive retail, the tariff flows straight through to the shelf. And this is the big one. San Francisco Fed research on the 2018–2019 Section 301 tariffs on China found roughly 60–70% of the duty showed up in higher US consumer prices within six months. Other studies of the 2018–2025 tariff waves put about 90% of the total burden on American companies and consumers combined, with foreign exporters absorbing only a small slice.
Where does a tariff dollar end up? (approx., based on Fed research of 2018–19 tariffs)
Approximate split — San Francisco Fed research found 60–70% of the 2018–19 China tariffs reached US consumer prices within six months; the rest was split between importer margins and supplier price cuts.
Why do presidents keep reaching for them, then?
Three reasons, and they're all real. Protection: tariffs make foreign goods pricier, giving domestic producers breathing room — the classic argument for steel, autos, and semiconductors. Leverage: the threat of tariffs is a negotiating weapon, which is exactly how the Graham Act's 100%-on-Russian-oil-buyers threat was designed to work. Revenue: $287 billion a year is not pocket change.
The cautionary tale is the Smoot-Hawley Tariff of 1930, which raised US duties to historic highs and helped trigger a global round of retaliation that deepened the Great Depression. Economists still cite it every time a new tariff wave starts, because the retaliation cycle is the part nobody controls: one country's tariff is another country's excuse.
How to read a tariff headline
Take this week's live example. The Graham Sanctioning Russia and Iran Act threatened 100% tariffs on countries buying Russian oil and 500% duties on Russian energy — meaning an American importer of that oil would owe the Treasury an amount equal to (or five times) the cargo's value. Hours before the deadline, Trump signed an executive order waiving most of it, citing the national interest. Ukraine called the waiver an "investment in a war." A bipartisan bill is now moving to block the parallel US-Russia diesel deal.
When you see a headline like that, ask three questions: Who's the importer? (that's who pays first), Can the cost be passed on? (competitive retail = yes, mostly), and What's the lag? (prices move 3–6 months after the tariff does — today's announcement is next quarter's receipt). Also watch for the word "reciprocal" — it means the US is matching another country's rate — and "de minimis," the low-value-shipment exemption that used to let cheap parcels skip duties entirely and is now largely suspended.

What happens next
Our take: tariffs are slow-moving weather, not lightning. The announcements make noise on day one; the prices arrive quietly, months later, spread across thousands of products so no single sticker screams "tariff." That's precisely why they're politically useful — and why the honest way to judge any tariff policy is to watch the CPI and PPI prints two quarters out, not the press conference. With September inflation already at 3.7% and the 10-year Treasury above 5%, the pass-through from this year's tariff waves is still working its way through the system. The next few inflation reports will tell us how much of that $287 billion landed on American households — and how much the importers and suppliers managed to swallow.
Frequently asked questions
Do foreign countries pay US tariffs?
No. The US importer of record pays the duty to Customs and Border Protection. Foreign exporters and governments have no legal role in the payment — though they may absorb part of the cost through lower prices to stay competitive.
Do tariffs raise prices for consumers?
Mostly, yes. Federal Reserve research on the 2018–2019 tariffs found 60–70% of the duty reached US consumer prices within six months, with the rest split between importer margins and supplier discounts.
What is the importer of record?
The party legally responsible for a shipment entering the US — usually the American buyer or its licensed customs broker. They file the entry documents, declare the value and classification, and pay every dollar of duty owed.
What happened with the Graham Act tariffs this week?
The law threatened 100% tariffs on Russian-oil buyers and 500% duties on Russian energy starting October 18, 2026. Hours before the deadline, President Trump signed an executive order waiving most of the measures, citing the national interest.
Tariffs are one of those rare topics where the most common belief about them is almost exactly backwards. Now you know the mechanics: the importer pays, the money splits three ways, and most of it finds its way to you — just slowly enough that nobody connects the headline to the receipt. Next time a tariff makes the news, you'll read it the way economists do: not as a tax on them, but as a down payment on your next shopping trip.
