It's very likely that for luxury items the price is what people are willing to pay. And it's adjusted for each country accordingly.
Thus, the change may simply be that profit margin for sales into the US drops (or rather than it skews that way).
But there are still many commodities where you're not pricing the product based on branding.
These commodities will likely still have the same price on the international market. And thus, consumers in the US will see the effects of tariffs in the price.
Such commodities could be finished goods, but also parts, machines or feedstock for industry in the US.
I'd also guess that if you look at what middle class people buy, these commodities make up a larger percentage of the expenditure -- than it does for wealthy people.
Making tariffs a very regressive tax.
Most people won't care about the price of luxury watch.
But most people will buy aluminum cans, etc.
