Just figured out where these fake tariff rates come from. They didn't actually calculate tariff rates + non-tariff barriers, as they say they did. Instead, for every country, they just took our trade deficit with that country and divided it by the country's exports to us.
So we have a $17.9 billion trade deficit with Indonesia. Its exports to us are $28 billion. $17.9/$28 = 64%, which Trump claims is the tariff rate Indonesia charges us. What extraordinary nonsense this is.

This tweet is correct, but it's actually worse than I thought: in calculating the tariff rate, Trump's people only used the trade deficit in goods. So even though we run a trade surplus in services with the world, those exports don't count as far as Trump is concerned.

This is truly amazing. The Deputy White House Press Secretary is claiming that I'm wrong, and that the "tariff rates" on Trump's chart were calculated by "literally" measuring every country's tariffs and non-tariff trade barriers.
To prove it, he screenshots the formula the USTR says was used to calculate the reciprocal tariffs we imposed on other countries. And when you back out the Greek symbols, what is that formula? Trade deficit/imports - exactly what I said it was.
I don't know if the Deputy Press Secretary was misinformed, or is just being misleading. Either way, the Trump administration did not "literally calculate tariff and non tariff barriers" to determine the tariff rates it's imposing on other countries. As I said, it divided our trade deficit with a country by our imports with that country, and then multiplied by 0.5 (because Trump was being "lenient").
Oh, and if our trade deficit/imports with a country is less than 10%, or we have a trade surplus with a country, Trump slapped a flat 10% tariff on that country.

This might be the first large-scale application of AI technology to geopolitics.. 4o, o3 high, Gemini 2.5 pro, Claude 3.7, Grok all give the same answer to the question on how to impose tariffs easily.
May Have Used AI To Come Up With The Numbers - Rohit on X
Here’s what the White House and its crack team of trade investigators seems to have done: Take the US’s goods trade deficit with any particular country, and divide it by the total amount of goods imported from that country. Cut that percentage in half, and there’s the US’s “reciprocal” tariff rate.
We can confirm this fits* the numbers for the first 24 countries listed, which we checked by hand because we could hardly believe it and also because we refuse to use AI for anything. Kudos to @orthonormalist and James Surowiecki, who both put it together, more or less.
Is the US . . . implying that all trade deficits are the result of unfair practices or currency manipulation? What about comparative advantage? David Ricardo is surely spinning in his grave. What about bananas? They don’t grow in the US! Is it worrying that some posters got this method when they asked major LLMs about easy ways to impose tariffs? This is bananas.
*The only discrepancies we found in that group were Sri Lanka, which had 87 per cent instead of 88 per cent, and what could be some messy rounding. The next 24 countries were a little messier, but could still more or less be explained by sloppy rounding, with the exception of Jordan, Tunisia and Kazakhstan, which were all off by a percentage point or two.
