How were Donald Trump’s tariffs calculated?
In total, more than 100 countries are covered by the new tariff regime.

US President Donald Trump has imposed a 10% tariff on goods from most countries being imported into the US, with even higher rates for what he calls the ”worst offenders”.
But how exactly were these tariffs – essentially taxes on imports – worked out? BBC Verify has been looking at the calculations behind the numbers.
What were the calculations?
When Trump presented a giant cardboard chart detailing the tariffs in the White House Rose Garden it was initially assumed that the charges were based on a combination of existing tariffs and other trade barriers (like regulations).
But later, the White House published what might look like a complicated mathematical formula.
But the actual exercise boiled down to simple maths: take the trade deficit for the US in goods with a particular country, divide that by the total goods imports from that country and then divide that number by two.
A trade deficit occurs when a country buys (imports) more physical products from other countries than it sells (exports) to them.
For example, the US buys more goods from China than it sells to them – there is a goods deficit of $295bn.
The total amount of goods it buys from China is $440bn. Dividing 295 by 440 gets you to 67% and you divide that by two and round up. Therefore the tariff imposed on China is 34%.
Similarly, when it applied to the EU, the White House’s formula resulted in a 20% tariff.
Are the Trump tariffs ‘reciprocal’?
Many commentators have pointed out that these tariffs are not reciprocal.
Reciprocal would mean they were based on what countries already charge the US in the form of existing tariffs, plus non-tariff barriers (things like regulations that drive up costs).
But the White House’s official methodology document makes clear that they have not calculated this for all the countries on which they have imposed tariffs.
Instead the tariff rate was calculated on the basis that it would eliminate the US’s goods trade deficit with each country.
Trump has broken away from the formula in imposing tariffs on countries that buy more goods from the US than they sell to it.
For example the US does not currently run goods trade deficit with the UK. Yet the UK has been hit with a 10% tariff.
In total, more than 100 countries are covered by the new tariff regime.‘
Lots of broader impacts’Trump believes the US is getting a bad deal in global trade.
In his view, other countries flood US markets with cheap goods – which hurts US companies and costs jobs.
At the same time, these countries are putting up barriers that make US products less competitive abroad.So by using tariffs to eliminate trade deficits, Trump hopes to revive US manufacturing and protect jobs.
But will this new tariff regime achieve the desired outcome?
BBC Verify has spoken to a number of economists. The overwhelming view is that while the tariffs might reduce the goods deficit between the US and individual countries, they will not reduce the overall deficit between the US and rest of the world.
“Yes, it will reduce bilateral trade deficits between the US and these countries.
But there will obviously be lots of broader impacts that are not captured in the calculation”, says Professor Jonathan Portes of King’s College, London.
That’s because the US’ existing overall deficit is not driven solely by trade barriers, but by how the US economy works.For one,
Americans spend and invest more than they earn and that gap means the US buys more from the world than it sells. So as long as that continues, the US may continue to keep running a deficit despite increasing tariffs with it global trading partners.
Some trade deficits can also exist for a number of legitimate reasons – not just down to tariffs. For example, buying food that is easier or cheaper to produce in other countries’ climates.
Thomas Sampson of the London School of Economics said: “The formula is reverse engineered to rationalise charging tariffs on countries with which the US has a trade deficit.
There is no economic rationale for doing this and it will cost the global economy dearly.”
The Director-General, Manufacturers Association of Nigeria (MAN), Segun Ajayi-Kadir, has described the rift between Dangote Refinery and Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN) as unfortunate, and a needless attack on private enterprise.
He noted that the strike had far-reaching implications on residents and businesses, as factories suffered cuts in production schedules, with a hike in transportation fare.
Fielding questions from reporters at MAN House, yesterday, while announcing the association’s coming Annual General Meeting (AGM), he revealed that imported products, which were not suffering disruption, were likely to fill the gap and if the rift rears its head again, it would affect daily workers and people in the logistics value chain that rely on the products made in those factories.
Meanwhile, PENGASSAN has said it decided to suspend its two-day strike to protect the jobs of its members in Dangote Refinery.The President, Festus Osifo, explained that the union was unsatisfied with the posting of about 800 sacked staff to Dangote’s subsidiaries to prevent job loss.
