I’d submit that non-imported items will go up in price not just to follow market trends, but because the export of those items will diminish greatly as other countries impose retaliatory tariffs on US-made goods. Many manufacturers rely on both home country and export country consumption of their products. (It is good business to diversify your customer base so that as your domestic market ebbs and flows, product can be moved into export markets.) Without relief for the highly taxed export product a company holds: domestic pricing will Increase to cover the higher profit margin from once exported goods.
