What tariffs has Trump announced and why?

Donald Trump has introduced tariffs on goods coming into the US from most countries around the world.

The US president argues that the taxes will boost domestic manufacturing and create jobs. But critics have warned of higher prices for consumers and damage to the global economy.

On Friday, the US Supreme Court struck down some of the most significant tariffs.

It ruled that Trump had exceeded his authority in using emergency powers to enact them on dozens of global trading partners.

But Trump said he would replace those measures with a 10% global tariff using a different law.

Tariffs are taxes on imported goods.

Typically, the charge is a percentage of a good’s value.

For example, a 10% tariff on a $10 product would mean a $1 tax on top – taking the total cost to $11 (£8.17).

The tax is paid to the government by companies bringing in the foreign products.

These firms may pass some or all of the extra cost on to their customers, which in this case means ordinary Americans and other US businesses.

They may also decide to import fewer goods.

Why is Trump using tariffs?

Trump says tariffs increase the amount of tax raised by the government, encourage consumers to buy American-made goods and boost investment in the US.

He wants to reduce the US trade deficit – the gap between the value of goods it buys from other countries and those it sells to them.

The president argues that the US has been exploited by “cheaters” and “pillaged” by foreigners.

Trump has also used the taxes to make other demands.

For example, when announcing tariffs against China, Mexico and Canada, he said the countries must do more to stop migrants and the illegal drug fentanyl reaching the US.

Some tariffs have been amended, delayed or scrapped after being announced.

What are Trump’s tariffs on individual countries?

Trump said he was moving forward with a 10% global tariff after the Supreme Court decision. It is unclear how that move and the decision will affect tariff rates set as part of US trade negotiations last year.

Negotiations had been going on with a number of countries, including America’s top three trading partners:

In April 2025, Trump said a “baseline” of 10% would apply to imports from almost all other countries, while nations considered the “worst offenders” in trade terms would face higher rates from August.

After a series of negotiations, these include:

What is the UK tariff deal?

The 10% rate applies to the first 100,000 UK vehicles exported every year – roughly the number sold in 2024. Additional cars face the standard 25% tariff.

The agreement also lets the two countries sell beef to each other.

Trump announced “the deal was done” in June 2025, but did not confirm the expected removal of the 25% rate which applies to UK steel exports. This is no longer expected to happen.

Which goods are affected by Trump’s tariffs?

Some taxes announced by Trump are on particular products, wherever they are made.

In addition, Trump ended an exemption for imports valued at $800 (£592) or less.

It means low-cost goods are no longer duty-free – a move affecting millions of packages sent every day, including those from online retailers like Shein and Temu.

The companies shipping the parcels now have to pay duties based on the tariff rate which applies to the country the goods were sent from. Otherwise, for six months, they can choose to pay a fixed fee of between $80 and $200 per package.

Why was the Supreme Court considering the legality of Trump’s tariffs?

The Trump administration brought in some of the tariffs using the 1977 International Emergency Economic Powers Act. Declaring an emergency under the law meant Trump could bypass Congress and other tariff procedures.

In August 2025, a US appeals court ruled that most of the tariffs introduced this way were illegal, but left them in place.

The White House asked the US Supreme Court to overturn that decision but it has instead upheld the lower court.

Trump has said that it would be a “complete mess” if the Supreme Court struck down his tariffs, and warned of difficulties if businesses were told they could claim refunds.

“It would take many years to figure out what number we are talking about and even, who, when, and where, to pay,” he said.

Have prices gone up for US consumers?

Some products have become more expensive – including toys, appliances and furniture as well as certain foodstuffs.

US inflation was 2.7% in the 12 months to December, down from 3% in September, but up from 2.4% in April, before most tariffs started.

Many firms say they are passing on the cost of tariffs to US customers, including Target, Walmart and Adidas.

The cost of goods manufactured in the US using imported components is also expected to rise.

For example, car parts typically cross the US, Mexican and Canadian borders multiple times before a vehicle is completely assembled.

How are tariffs affecting the US and global economies?

Trump was accused of throwing the global economy into turmoil when he announced the first tariffs of his second presidential term.

It forecast global growth of 3.2% for 2025, and 3.1% in 2026. That was a slight increase from its July predictions, but still below the 3.3% it had projected for both years before Trump’s measures were announced.

It thinks the US economy will grow by 2% in 2025, and 2.1% in 2026. That’s down from the 2.8% growth recorded in 2024, but still the fastest among the world’s most advanced economies.

The economy grew at an annual rate of 4.3%, up from 3.8% in the previous quarter. That was better than expected, and marked the strongest growth in two years.

Imports – which count against growth – continued to decline during the period.
