WHAT?

A tariff is a broad term for a tax imposed by a government on goods or services crossing its borders, primarily for imports but sometimes exports. It serves purposes like raising revenue, protecting domestic industries, or influencing trade policies.

Tariffs can be fixed per unit or as a percentage of value. For items like coal or metal, it is fixed on weight like per tonne and for costly items like diamonds, cars , it is fixed as a percentage of value. It is a tax similar to the Customs duty. 

Why does donald trump impose tariffs? 

Donald Trump has imposed tariffs during his presidency to achieve several stated goals, based on his economic and geopolitical strategy. 
 

Trump argues that the U.S. has been disadvantaged by large trade deficits, with other countries imposing higher tariffs on U.S. goods than the U.S. does on theirs. He has implemented "reciprocal tariffs" to match or exceed the tariffs other nations impose, aiming to level the playing field. For example, the U.S. imposes a 2.5% tariff on passenger vehicles, while the EU (10%) and India (70%) impose higher rates.
 

Trump claims tariffs will encourage companies to produce in the U.S., boosting domestic manufacturing and creating jobs. Trump has declared trade deficits and reliance on foreign goods, like Chinese drug precursors or critical minerals, as threats to national security.

Further, tariffs are used as a tool to pressure countries on non-trade issues, such as immigration and drug trafficking e.g. to stop import of  fentanyl from China, Mexico, and Canada. 
 

Tariffs generate government revenue, with estimates suggesting they accounted for 5% of US government revenue by July 2025, up from 2% historically. 

But will the tariffs help the USA?

Some evidence from Trump’s first term (2017–2021) suggests tariffs on steel and aluminum reduced imports and spurred domestic investment. A 2023 US report found that tariffs reduced Chinese imports and encouraged reshoring in manufacturing.

Steel imports fell by nearly one-third from 2016 to 2020, with over $10 billion invested in new U.S. mills.
 

Tariffs have pressured countries to negotiate trade deals. For example, the EU agreed to 15% tariffs and Vietnam accepted 20% tariffs to avoid 46%. These deals suggest Trump’s threats can extract concessions, potentially benefiting U.S. exporters.
 

Tariffs have increased federal revenue, with $80 billion collected in one year during Trump’s first term (2% of total U.S. tax revenue). Strategic Independence: Tariffs on critical goods like pharmaceuticals and semiconductors aim to reduce reliance on adversaries like China, potentially strengthening national security by rebuilding domestic supply chains.
 

ISSUES

But tariff have other sides too. Most economists agree that U.S. consumers bear much of the tariff cost through higher prices. A 2019 study found Trump’s washing machine tariffs raised prices by $86 per unit, costing consumers $1.5 billion annually. A 2025 estimate projects Trump’s tariffs could cost households $1,300-$5,200 per year, hitting lower-income families hardest due to their reliance on imported goods.
 

A report projects that the  tariffs announced by April 2025 could reduce U.S. GDP by 8% and wages by 7%, with a middle-income household facing a $58,000 lifetime loss. Retaliatory tariffs from trading partners could exacerbate this, as seen in Trump’s first term when China’s retaliation harmed U.S. farmers.
 

Tariffs have caused market volatility and strained relations with allies. Japan’s Nikkei 225 fell 7.8% after a 25% U.S. tariff on cars, and Mexico’s GDP could drop 16% due to its trade dependence on the U.S. The IMF and OECD downgraded 2025 global growth forecasts, citing U.S. tariffs.
 

Tariffs are expected to raise U.S. inflation by 0.2–2 percentage points, with businesses passing costs to consumers. Market swings, like the sharp stock sell-offs in April 2025, reflect uncertainty, potentially deterring investment and hiring.

And at last, While tariffs give the U.S. leverage, they risk alienating allies and escalating trade wars potentially undermining diplomatic relations.
