“United States tariffs are paid by domestic importers and the costs are passed on almost entirely to American businesses and consumers.”

• Legal/mechanical fact: U.S. Customs and Border Protection collects duties from the importer of record — a U.S.-based business (or its customs broker) — at the time goods enter U.S. commerce. Foreign governments and foreign exporters never remit money to the U.S. Treasury for tariffs.
• Amiti, Redding & Weinstein (Journal of Economic Perspectives, 2019) found that the 2018 tariffs were passed through 'completely' into U.S. domestic prices of imported goods, implying the full incidence fell on U.S. importers and consumers, with an estimated aggregate real income loss of roughly $1.4 billion per month by late 2018.
• Fajgelbaum, Goldberg, Kennedy & Khandelwal ('The Return to Protectionism,' Quarterly Journal of Economics, 2020) estimated near-complete pass-through of the 2018 tariffs to U.S. prices and found essentially no decline in foreign exporters' pre-tariff prices, i.e., U.S. buyers bore the burden; they estimated ~$51 billion in annual costs to U.S. consumers and importers.
• Cavallo, Gopinath, Neiman & Tang (AER: Insights, 2021) documented that tariffs passed through almost one-for-one into U.S. border (duty-inclusive) import prices, with foreign exporters not cutting their dollar prices.
• Flaaen, Hortaçsu & Tintelnot (American Economic Review, 2020) found the washing-machine safeguard tariff raised U.S. retail washer prices by roughly 12%, with costs borne by American consumers — including on domestically produced substitutes.
• BLS Import/Export Price Indexes (which exclude duties) showed little decline in foreign exporters' dollar prices during the 2018–19 trade war, consistent with foreign sellers not absorbing the tariff.
• Tax Foundation and other tax-policy analysts classify tariffs as a tax on American importers that functions as a consumption tax largely borne by U.S. households and firms.
• The claim's phrasing 'American businesses and consumers' is broad enough to cover both channels economists observe: margin compression at U.S. importers/retailers and higher retail prices for households.

• 'Almost entirely' is an overstatement in some episodes: for the 2025 tariff round, private-sector analyses (e.g., Goldman Sachs estimates widely reported in mid-2025) attributed roughly 15–25% of tariff costs to foreign exporters cutting prices, with the remainder split between U.S. firms' margins and consumers.
• Exchange-rate movements can shift part of the burden abroad: the Chinese renminbi depreciated substantially against the dollar in 2018–19, partially offsetting tariff-induced price increases for U.S. buyers (an implicit foreign-borne cost), and a stronger dollar has a similar effect.
• Pass-through to final retail prices is often incomplete and slow — Cavallo et al. found retail price increases far smaller than border price increases in 2018–19 — meaning the burden falls on importer/retailer margins rather than consumers; some sellers also source from exempt countries, blunting the consumer price effect.
• Economic theory and some product-level evidence (e.g., certain steel and specialized inputs) allow for terms-of-trade gains where large-country tariffs do push foreign supplier prices down; empirically small in the U.S. case, but not literally zero.
• Foreign producers also bear costs indirectly through lost export volumes, profits, and market share, which the phrase 'almost entirely' to Americans glosses over, even though those losses are not tariff payments.

• U.S. customs law makes duties a debt of the importer of record to the United States, so the legal payer is the importer, not the exporting country or foreign government. See 19 CFR §141.1 at https://www.ecfr.gov/current/title-19/chapter-I/part-141/section-141.1.
• The Congressional Research Service describes tariffs as taxes on imported goods and explains that they are collected from importers, supporting the first half of the claim. See https://crsreports.congress.gov/product/pdf/IF/IF11030.
• FactCheck.org, assessing claims that China pays U.S. tariffs, concluded that tariffs are paid by U.S. importers and that businesses commonly pass the costs along to consumers through higher prices. See https://www.factcheck.org/2019/05/trumps-dubious-claims-about-china-paying-tariffs/.
• Amiti, Redding and Weinstein’s NBER paper on the U.S.-China trade war found that U.S. tariffs were passed through largely/almost entirely to U.S. firms and consumers, with foreign exporters absorbing little of the cost in prices. See https://www.nber.org/papers/w26610.
• Fajgelbaum, Goldberg, Kennedy and Khandelwal’s peer-reviewed QJE study found U.S. import tariffs were passed through to U.S. domestic prices, while losses to consumers and importing firms outweighed gains to protected firms/workers. See https://academic.oup.com/qje/article/135/1/1/5626442.
• The U.S. International Trade Commission’s 2023 review of Section 232 and Section 301 tariffs found that the tariffs raised prices of covered imports and affected downstream U.S. industries, consistent with much of the burden falling on U.S. businesses and consumers. See https://www.usitc.gov/publications/332/pub5405.pdf.

• The wording 'passed on almost entirely to American businesses and consumers' is broadly supported for recent U.S. tariffs, but it is an incidence claim, not an accounting fact. Some importers, wholesalers, or retailers may absorb part of the tariff through lower margins, especially in the short run.
• Cavallo et al. found near-complete pass-through of recent tariffs into U.S. import prices at the border, but more mixed pass-through into retail prices; some large retailers absorbed tariff costs rather than immediately raising consumer prices. That caveat weakens an absolute reading that consumers personally pay almost all tariff costs. See https://www.aeaweb.org/articles?id=10.1257/aeri.20190536.
• Tariff incidence can vary by product, market power, contract timing, exchange rates, supply-chain adjustments, and demand/supply elasticities. In some cases foreign exporters may cut pre-tariff prices or U.S. firms may change suppliers, so the statement should not be read as a universal law for every tariffed good.

• By U.S. law, tariffs are a tax collected by U.S. Customs and Border Protection (CBP) directly from the domestic 'importer of record.' Foreign governments and foreign manufacturing firms do not pay the U.S. government.
• Multiple empirical studies on the 2018-2019 trade war, including major papers published by the National Bureau of Economic Research (NBER) and the American Economic Association, found a near 1-to-1 passthrough of tariff costs. They concluded that foreign exporters generally did not lower their border prices, meaning the total cost of the tariffs was paid by U.S. importers.
• A March 2023 statutory report by the U.S. International Trade Commission (USITC) analyzed the Section 232 and Section 301 tariffs and confirmed that the costs were passed on almost entirely to U.S. importers, leading to increased costs for U.S. businesses that rely on imported components and higher prices for American consumers.

• While the physical payment of the tariff is made by the U.S. importer, the theoretical economic burden (incidence) can be shared if foreign exporters lower their prices to maintain market share. While empirical data shows this was rare in recent U.S. trade conflicts, a small subset of specific industries saw foreign suppliers absorb a fractional amount of the tariff.
• Macroeconomic adjustments, such as the depreciation of a foreign currency (e.g., the Chinese yuan depreciating against the U.S. dollar), can indirectly offset some of the cost for U.S. buyers. In these cases, the foreign exporting economy experiences economic friction, even though they do not write a check to the U.S. government.
• Some American businesses choose to absorb the higher import costs by reducing their own profit margins rather than passing 100% of the cost to the final retail consumer, though the cost is still borne by an 'American business' as the claim states.

• U.S. tariffs are legally paid to Customs by the domestic importer of record, not directly by the foreign government. Studies of the 2018–19 tariffs found nearly complete pass-through into the tariff-inclusive prices paid by U.S. importers, indicating that U.S. importers bore almost all of the border cost.[2][3]
• The U.S. International Trade Commission review summarized by PolitiFact found that tariffs were paid primarily by U.S. importers while prices received by Chinese exporters were largely unaffected. It also found that importers passed most or all of the costs to consumers or U.S. producers using Chinese inputs.[7]
• Federal Reserve research found that 2018–19 tariffs were passed through fully and quickly to consumer-goods prices, while the Boston Fed found that small-business importers generally expected to pass a substantial portion of tariff-related cost increases to consumers.[2][8]

• The phrase "almost entirely to American businesses and consumers" is too broad if interpreted as an immediate, dollar-for-dollar burden on retail consumers. Recent Federal Reserve estimates for 2025 tariffs found retail-price pass-through of about 15% using realized tariff rates, or about 20% under a broader exposure measure.[9]
• A New York Fed study estimated that only about 26% of the 2025 tariff increase passed through to consumer prices relative to less-exposed goods; 64% of that consumer-price effect was direct and 36% reflected higher input costs and increased domestic markups.[1]
• Tariff incidence can vary by product, market power, exchange rates, demand, and timing. Historical evidence from U.S. sugar duties found that only about 40% of tariff increases passed through to consumer prices, showing that importers and consumers do not necessarily absorb the entire statutory tariff.[10]
• The claim conflates legal payment with ultimate economic incidence. Importers remit the tariff, but they may absorb some cost through lower margins, alter sourcing, reduce imports, or shift part of the burden to foreign suppliers; therefore, "almost entirely" is well supported for some recent tariff episodes at the border but not universally for all tariffs or all downstream prices.[3][10]

• U.S. customs law requires the importer of record—almost always a domestic firm—to tender duty payments to CBP; foreigners do not remit the tax.
• Peer-reviewed analyses of the 2018–19 Section 232/301 tariffs (Amiti-Redding-Weinstein JEP 2019; Fajgelbaum et al. QJE 2020) found tariff-inclusive import prices rose roughly one-for-one with the statutory rates, implying foreign exporters did not cut pre-tariff prices.
• U.S. producer-price and downstream input-cost data, plus selected retail scanner studies, show the extra cost appearing in American business costs and consumer prices rather than being absorbed abroad.
• Fact-checkers have repeatedly labeled the claim that ‘China/foreigners pay the tariffs’ false on the same legal-plus-incidence grounds.

• Optimal-tariff / terms-of-trade theory predicts a large importer can force some burden onto foreign exporters via lower export prices; a few product-level papers estimate 10–30 % foreign absorption.
• Pass-through to final retail prices is sometimes incomplete; U.S. importers or retailers absorb part in margins (still American businesses, but not ‘passed on’).
• Incidence is not uniform across all historical U.S. tariffs, all products, or longer time horizons once exchange rates, rerouting, and retaliation occur.
• ‘Almost entirely’ overstates the precision of the empirical range; several studies find high but not 100 % domestic incidence.
