Well if the US manufacturers need to import chips (read: the item proposed to be subject to a 100% tariff) in order to make their phone with a “competitive advantage”, as you’ve claimed above, then the manufacturers will be impacted by tariffs.

That cost then gets passed onto the consumer.

The phone assembled in the US using imported parts is indirectly impacted by tariffs. Consumers only care about the end price, not who paid what tariff and which point of manufacturing.

I don’t know how many ways people can explain this to you and you don’t get it. I’m assuming you’re trolling because this is extremely basic stuff.
