Then the BBC “Expert” needs to look again.
It is simply an import-export formula, and then for some unknown reason he divided it by 2!

The Trump tariff formula, as explained by experts, involves a straightforward calculation based on the U.S. trade deficit with each country.
The formula divides the trade deficit by the total imports from that country, then halves the result to determine the tariff rate.
For example, if the U.S. has a $295 billion trade deficit with China and imports $440 billion in goods, the calculation yields a 67% rate, which is halved to 34%.
Critics argue that this method is flawed, as it oversimplifies complex trade dynamics and misrepresents global trade economics.
The American Enterprise Institute noted that the formula exaggerates tariffs assumed to be imposed by foreign nations.
