Countries like North Korea and Russia are already covered by sanctions
Are the two mutually exclusive? Because using the same formula they apply to other countries, Russia would have tariffs as high as 84%. (I confess to using an LLM to get me the data.)

There are secondary tariffs on those countries who buy from Russia and Venezuela or Iran. i.e. if you buy oil from Venezuela, then your export of clothing will invite 25% tarrifs.
