The country of origin in that case is the last country in which the product significantly changed value from being manufactorered locally and it requires a facility to do so. Slapping a sticker on something is not enough.

My point is, that there is indeed a significant change, when parts are put together into a product. In the case of almost 150% tariffs, I am sure that this would be an attractive solution.

I am not looking for a loophole. Just stating the obvious and trying to understand how the USA handles these challenges. Slapping tariffs on countries seems naive, when globalization has intertwined every country into each other. Especially when it comes to trade and production
