Just a thing on that, and the manufacturers and other product vendors won't tell you. The USA is a massive market for a lot of companies. If competitors lose market share in the US, they will raise prices elsewhere to subsidize the US market. This happens in all other industries. It gets more complex when you have US-specific system builders relying on imports, and strict partnerships, mostly from China. Distribution will eventually shift, with products stored in tariff-friendly countries before being exported to the US.
I doubt the US will escalate the trade war, that of tariffs, into sanctions because it would make crucial materials hard to access for their localized industry.
For how long will this go on, well, it could be long, it could be short, but the impact on retail will linger in the aftermath. This is either out of necessity, for recuperation, and/or because the consumer is a willing buyer. Neither will they tell you this.
