What’s in Effect
The main tariffs in force in October 2026 rest on two trade laws. Section 232 tariffs, imposed on national security grounds, have covered steel and aluminum since 2018 and copper since 2025. An April 2026 proclamation set them at 50% on the metals and 25% on many products made from them. Section 232 tariffs on autos and lumber also survived the Supreme Court ruling described below.
Section 301 tariffs on Chinese goods date from 2018. Increases decided in 2024 set them at 100% on electric vehicles and 50% on solar cells and, from 2025, semiconductors. Since 24 July 2026, new Section 301 tariffs have applied to 60 economies that supply 99.4% of U.S. imports. Their rate is 10% or 12.5%, and goods under Section 232 are exempt.
The Supreme Court struck down the largest layer in February 2026
On 20 February 2026 the Supreme Court ruled 6–3 in Learning Resources, Inc. v. Trump. It held that the International Emergency Economic Powers Act (IEEPA) does not authorise the President to impose tariffs. That ruling removed the single largest source of the 2025 increases: the IEEPA baseline tariff, the country-specific top-ups on China, the EU and others, and the emergency orders covering Canada, Mexico and fentanyl. Section 232, Section 301 and normal tariff rates were untouched.
By Global Trade Alert’s estimate, the trade-weighted average U.S. tariff fell from 15.3% to 8.3%. Importers had paid about $166 billion in IEEPA tariffs. By 21 August 2026, U.S. Customs and Border Protection had certified about $107 billion of refunds, according to court filings cited by the Penn Wharton Budget Model.
Within hours the President invoked Section 122 of the Trade Act of 1974 and imposed a 10% surcharge effective 24 February 2026. Section 122 is time-limited: that order ran 150 days, to 24 July 2026, when the Section 301 tariffs on 60 economies took its place.
How High Tariffs Have Been
Penn Wharton’s rate counts the duties actually collected. The Budget Lab at Yale measures the rate set in law instead, before buyers shift away from tariffed goods, holding import shares at their 2024 pattern. On that measure the rate reached 18.0% in October 2025, the highest since 1934. Yale put its average rate set in law at 11.0% in August 2026, and the cost of those tariffs at about $1,100 a year per household.
How a Tariff Works
A tariff raises the price of the imported good, which helps domestic producers of that good and raises costs for the businesses and consumers who buy it. The U.S. International Trade Commission (USITC) found all three effects after the 2018 steel tariffs, as the 2018 figures below show. The debate is over net effects: whether the gains to domestic producers plus strategic benefits outweigh the losses to buyers plus deadweight costs plus retaliation. Deadweight costs are the efficiency lost when a tariff distorts what people buy and where resources go.
Gains to a Few, Costs Spread Thinly
Jobs in industries that use steel or inputs made of steel outnumber jobs making steel by roughly 80 to 1, Lydia Cox and Kadee Russ estimated in 2018. A steel tariff’s gains go to a few visible workers, while its costs are spread thinly across many more, and that gap shapes tariff politics.
Bush Steel Tariffs (2002): 8–30%
Steel jobs saved (projected before the tariffs)~3,500 (for a proposed 15–20% tariff)
Cost to steel users (same projection)~$2 billion/year
Jobs lost in steel-using industries26,000 to 200,000 (published estimates)
Duration21 months (lifted after a World Trade Organization ruling)
The figures most often quoted for 2002 are forecasts and contested estimates. The 3,500 jobs and $2 billion come from a January 2002 policy brief by Gary Hufbauer and Ben Goodrich. The brief was about a proposed tariff of 15% to 20%. It was written before President Bush chose rates of 8% to 30%.
The 200,000 is the Trade Partnership’s estimate of jobs lost to higher steel prices in 2002, in a study for a coalition of steel-consuming industries. Its authors said the data could not yet show how much of the price rise the tariffs caused.
Later studies measured what happened. Lake and Liu found that the tariffs did not raise local steel employment but cut local employment in steel-using industries for years after they ended. Lydia Cox found large, lasting falls in those industries’ exports and employment.

Aaron Flaaen and Justin Pierce, economists at the Federal Reserve Board, compared manufacturing industries by how exposed they were to all the 2018 tariffs, including other countries’ retaliation. Moving an industry from the 25th to the 75th percentile of exposure was associated with 1.4% lower manufacturing employment by August 2019. Protection from imports added a little, but higher input costs and retaliation took away more, as the chart shows. These are short-run effects relative to less-exposed industries, not a count of jobs lost nationally.
How to read it: each bar is the change in manufacturing employment that Flaaen and Pierce link to one channel of the 2018 tariffs, or to all three together. Each compares an industry at the 75th percentile of exposure with one at the 25th.

Institute for Supply Management manufacturing index, December 202547.9 (contracting for a 10th month in a row)
The same index, September 202654.5 (expanding for a 9th month in a row)
Manufacturing employment fell through 2025 as tariffs rose, and recovered most of that fall in 2026 as tariff rates came down. Neither move can be credited to tariffs alone, because a national total also reflects everything else happening in the economy.
Productivity and Imports
Ball State University (2000–2010)87.8% of job losses from productivity growth
Trade share13.4% from trade (growing demand added back 1.2%)
China import competition (Acemoglu, Autor, Dorn, Hanson and Price)2.0–2.4 million jobs lost across the economy, 1999–2011
Manufacturing peak19.6 million (June 1979)
Latest12.65 million (September 2026, preliminary)
Rising productivity, driven chiefly by automation and information technology, explains most of the fall in manufacturing employment from 2000 to 2010, by Ball State’s estimate. Import competition from China mattered too: it caused local job and income losses that persisted for years after the shock levelled off around 2010. And even if a tariff blocks imports and restores some production, the jobs may not come back one-for-one if the surviving plants are highly automated.
The Trade Deficit Question
The goods-and-services deficit rose from $498 billion in 2017 to $932 billion in 2025, the largest in the Bureau of Economic Analysis (BEA) series back to 1960. It fell in 2019 and 2023, but there has been no sustained narrowing since the tariffs began in 2018.
How to read it: the line is the annual U.S. trade deficit in goods and services, in billions of current dollars. It runs from 2017, the year before the 2018 tariffs, to 2025, and the axis starts at zero. Source: BEA and Census, U.S. International Trade in Goods and Services, annual revision of 9 June 2026, Table 1.
Deficits with single countries are weak scorecards. The goods deficit with China fell from $417 billion in 2018 to $202 billion in 2025, but the deficits with Vietnam, Mexico and Taiwan grew as sourcing moved to them.
The overall deficit depends on more than trade policy. The current account is the trade balance plus other items, chiefly net income on cross-border investments. A country that imports more than it exports gives foreigners claims on its assets in exchange. So by balance-of-payments accounting, the current account deficit must equal the inflow of foreign capital, which rises with foreign demand for U.S. assets. The economists Kimberly Clausing and Maurice Obstfeld call the effect of tariffs on the trade deficit ambiguous.
What Supporters Point To
National securityDomestic capacity in semiconductors, rare earths, pharmaceuticals, and defense inputs has strategic value that output statistics underweight. In 2024 the Biden administration decided to raise Section 301 tariffs on Chinese electric vehicles, semiconductors, solar cells and other strategic goods. It said the increases would support investments under the Inflation Reduction Act and the Bipartisan Infrastructure Law. Even Kimberly Clausing and Maurice Obstfeld, economists who oppose broad tariffs, accept that defense production may justify a national interest in making things at home. But they find subsidies usually the better tool.
The China shock was realImport competition from China cost 2.0–2.4 million U.S. jobs from 1999 to 2011, by the estimate of Acemoglu, Autor, Dorn, Hanson and Price. The losses lasted for years in the communities hit.
Bargaining powerTariffs sometimes extract concessions. In May 2019 the United States lifted its steel and aluminum tariffs on Canada and Mexico. Both countries dropped their retaliatory tariffs, and each agreed with the United States to monitor steel and aluminum trade. In 2025 the Trade Representative, Jamieson Greer, said more than 75 trading partners had approached the United States after the April tariffs.
Manufacturing multipliersEnrico Moretti estimated that each additional manufacturing job in a U.S. city creates about 1.6 jobs in local goods and services in the same city. Factory closures devastate towns; tariffs that preserve strategic clusters have spillover value beyond the direct headcount.
COVID exposed fragilityA 2021 White House review found that the COVID-19 pandemic disrupted supplies of medical products, including essential medicines, and caused a global shortage of semiconductor chips. Some reshoring via tariffs buys resilience that free-trade models don’t price.
Protected industries gainedSteel capacity utilization reached 80% in 2019 and 81% in 2021, continuing a rise that began in 2016. A 2021 report by Adam Hersh and Robert Scott of the Economic Policy Institute counted the plans steel producers announced after the tariffs. They added up to more than $15.7 billion of investment in new or upgraded plants and at least 3,200 direct jobs.
Investment followedIn October 2025 Stellantis announced a $13 billion U.S. investment that it said would add 5,000 jobs over four years. The president of the United Auto Workers credited targeted auto tariffs.
Most of these points have answers:
- Clausing and Obstfeld note that a security case gives little reason for tariffs on consumer goods that are not strategic.
- On the China shock, Autor, Dorn and Hanson wrote that the 2018 trade war raised U.S. product prices but did not expand employment in the protected industries.
- The 2019 concessions came from lifting tariffs, not keeping them.
- Moretti calls his local multiplier an upper bound for the national one, and writes that large multipliers do not by themselves justify government intervention.
- Protected industries do gain some jobs, but in the three earlier episodes on this page, losses elsewhere outweighed them.
- Investment pledges such as Stellantis’s count the jobs promised, not those lost among the buyers of the protected goods.
What Critics Point To
Regressive taxTariffs work like a consumption tax, which falls hardest on lower-income households because they spend a larger share of their income. In August 2026 the Budget Lab at Yale estimated the burden on the lowest-income tenth of households at 1.6% of after-tax income. That is about three times the 0.5% for the highest-income tenth.
Downstream destructionFlaaen and Pierce found that losses from higher input costs and retaliation outweighed the gain from protection in more-exposed industries. The U.S. International Trade Commission (USITC) estimated $3.48 billion in downstream output losses in 2021 alone.
RetaliationMajor tariff actions have drawn retaliation. China answered the 2009 tire tariffs with antidumping duties on U.S. chicken parts. By the estimate of the Peterson Institute for International Economics, the duties cost that industry about $1 billion in sales. By a U.S. Department of Agriculture estimate, retaliation against the 2018 tariffs cut farm exports by more than $27 billion from mid-2018 to the end of 2019, mostly to China. The government paid farmers $23 billion.
Trade diversion, not reshoringChina’s share of U.S. imports fell from nearly 22% before June 2018 to 9% in 2025, but sourcing moved to Vietnam, Taiwan and Mexico. Total U.S. imports still rose 4% in real terms in 2025, Chad Bown found, which suggests little reshoring, though his paper does not measure it directly. The USITC estimated that the Section 301 tariffs raised the value of domestic production by only 0.4%.
They become permanent“Temporary” tariffs create political constituencies for permanence. The 2018 Section 301 tariffs on China are still in place and were raised in 2024 on about $18 billion of annual imports. The Section 232 steel and aluminum tariffs were doubled to 50% in June 2025.
Expert consensusIn a 2021 survey of 1,422 members of the American Economic Association, 95% agreed, fully or with provisos, that tariffs and import quotas usually reduce general economic welfare. When the Clark Center asked its panel of economists in March 2018 whether new steel and aluminum tariffs would improve Americans’ welfare, none of the 40 who answered agreed.
Supporters reply that shifting imports from China to other countries serves the strategic aim even without reshoring. Clausing and Obstfeld accept that tariffs can move trade toward more reliable partners, though some of the shift may be goods routed through third countries. The Budget Lab at Yale’s model also projects U.S. manufacturing output 1.3% higher in the long run. The same model finds that gain more than offset by losses elsewhere, such as construction, down 2.2%, and mining, down 1.0%.
No, not on net. In each of the three earlier episodes on this page, jobs gained in the protected industry were outweighed by jobs lost elsewhere. Those jobs were lost in steel-using industries after 2002, in retail after the 2009 tire tariffs, and in industries hit by higher input costs and retaliation after 2018. The 2025 tariffs have not been followed by a manufacturing jobs gain either. Where both figures exist, each job saved cost, or was projected to cost, about 14 to 23 times its annual pay.
The case for some tariffs on national security grounds is a different claim, about strategic goods rather than manufacturing jobs overall.
Four common claims, against the evidence
Claim“Tariffs bring back manufacturing jobs.”
Not on netProtected industries gain some jobs, such as about 4,200 at iron and steel mills from March 2018 to December 2019. But input costs and retaliation outweighed protection in more-exposed industries, and manufacturing jobs fell 113,000 in 2025.
Claim“Tariffs reduce the trade deficit.”
Not supportedThe goods-and-services deficit rose from $498 billion in 2017 to $932 billion in 2025, the largest in the Bureau of Economic Analysis series back to 1960. The deficit with China fell, but trade moved to Vietnam, Mexico and Taiwan.
Claim“Tariffs are just a tax on Americans.”
Largely supportedStudies of the 2018 tariffs found them fully passed through to the prices of imported goods. The Budget Lab at Yale put the cost of the tariffs in force in August 2026 at about $1,100 a household a year. But some tariffs also raise domestic production, as the U.S. International Trade Commission found for steel.
Claim“Tariffs are necessary for national security.”
Partly supportedDefense production can justify supporting a domestic industry, though economists who accept that usually prefer subsidies. Section 232 tariffs, imposed on national security grounds, now also cover lumber and products made from steel and aluminum, such as farm equipment.

What would change this conclusion
This article concludes that: (1) tariffs add some jobs and output in the industries they protect; (2) in the 2002, 2009 and 2018 episodes, losses in industries that buy the protected goods, in retail or from retaliation outweighed those gains; (3) each job saved cost, or was projected to cost, many times its pay; (4) the trade deficit was larger after the tariffs, not smaller.
These conclusions would be falsified by:
• A study of the 2025 and 2026 tariffs, like Flaaen and Pierce’s for 2018, that counts input costs and retaliation and finds more-exposed manufacturing industries gaining jobs against less-exposed ones
• Bureau of Labor Statistics data showing manufacturing employment well above its April 2025 level for three years or more. A study would also need to credit the rise to tariffs rather than to the wider economy.
• A tariff whose cost per job saved, measured after the fact, came in below the pay of the jobs it protected
