Do you live in some sort of academic hypothetical bubble? The trade war between US and China effects flow of goods and services both ways. In modern global logistics and manufacturing no country is able to 100% supply all the material needed from start to final assembly. Something somewhere along the lines would have came from another country. In this case there will definetly be material that would have criss crossed between these 2 nations and hence attracted levied tarrifs even if the final goods aren't ments for US consumption. Secondly why would vendors reduce supply to US based simply on tariffs if there is demand (Which is by far the biggest market world wide for IT parts)? The cost are simply passed on downstream. Vendors will raise prices across the board for other regions not just to cover the increased cost of production but to also maintain pricing structures to discourage grey importing.
