The final quoted portion doesn't seem to agree with your final statement though?

> Those price increases are estimated to fully offset the 30 percent of price increases absorbed by U.S. businesses that import goods, so the net effect of tariffs is to raise U.S. consumer prices by the full portion of the cost of the tariffs borne domestically (95 percent)."

The idea expressed previously in your excerpts is that domestically-produced US goods do increase their revenues by the amount that their produced-abroad competitors. So things are okay from that perspective.

But what that final quotation says is that those increased revenues are 95% paid for by US consumers. In other words, they "effectively pay the tax."
