Am I understanding this right? 1) US customer pays huge import tax on imported goods in the form of higher prices. 2) Seller sends the collected tax to the US government 3) US government will refund all/most of that tax back to the seller after this ruling 4) Seller gets to keep the returned tax money as pure profit (no refund to customer)
The importer CAN be the seller, but other times the importer is a middleman in the supply chain.
