Six months into tariffs, businesses have no idea how to price anything

I don't understand why there isn't a market or company that develop already to move all items to low tariff area before sending to US.

I know that manufacturing things here in Europe, there already used to be round trip by airplane and co to try to lower VAT paid on purchases to the maximum.

Because it is not allowed and it does not count. It is the origin country that counts, even if you ship via another 3rd party country.

This is the intuition for tariffs for countries like Vietnam (where China used to send a lot of goods to for repackaging). Not a new idea, and one that customs will aggressively police.

Mexico has a huge network of importers for doing exactly this and it predates both administrations.

The invoicing system there is highly gamed and corrupt (not that anywhere isn’t).

All of this tariffing has created a lot of new opportunities for businesses who operate in grey areas.

Vietnam is partly that. Production virtually "moved" from China to Vietnam pretty fast with various degrees of fakery. Not every company can pull it up, Nintendo for instance if probably more legitimate than others, but that's a thing.

That's covered, if you try to go to an intermediary county and they find out they will raise your tariffs back up to 150% for breaking the deal, it's built in to the agreements

That doesn’t really make sense… essentially the choice to do this isn’t in the hands of any nation, rather any business in the nation could try to do this and the government has no real way to know.

You could try to raise tariffs on a whole country because one company in that country was falsifying country of origin… but it’s inevitable
