yes, as with the solar tariffs, the cost of imported inputs increase which will cut off the bottom part of the market (buy side) that is price-sensitive.
However, it wont increase the price of anyone who was already buying US produced solar or steel. It will simply switch over some buyers from imported solar and steel to domestic steel.
If the business development people at the solar and steel companies are smart they will virtue-sell anyways. Yes Mr. Customer, the cost of the transaction is increasing but only by the amount that the solar/steel increased due to a switch from imported solar/steel to domestic solar/steel.
If you were a buyer of these products would you be upset if you had to pay 20% more to buy US-production? especially given the tax break you just received?
