I have three theories, based this article.
1. The administration used an LLM on certain data and it incorrectly conflated the countries.
2. Certain companies listed regions of export to avoid customs, duties, or for other reasons and it now indirectly got exposed. The article alludes to this without saying so?
3. The administration listed what seemed like inconsequential regions for the purpose of preventing Australia, for this example, of just saying it was exported from Norfolk Islands to dodge tariffs. Although, this is giving the administration way too much credit and if they are reading this don’t steal this as reason. :-)
So the conclusion is that the intern failed geography and did not realize that those aren't countries.
Everyone is reacting to this like it's a mystery. The architect literally wrote down the why: https://news.ycombinator.com/item?id=43594549
There are multiple of these explanations and none od them is consistent with actual decisions.

(when describing the model) Let ε<0 represent the elasticity of imports with respect to import prices...
(when implementing the model) The price elasticity of import demand, ε, was set at 4.
4 is less than 0, right? Right?!?
> The recent experience with U.S. tariffs on China has demonstrated that tariff passthrough to retail prices was low (Cavallo et al, 2021).
The line that says "sure, tariffs won't cost consumers _that_ much", and they don't even have a bibliographic entry for Cavallo et al. 2021.
