: Limited effectiveness, the US reluctantly opens up a loophole for aluminum tariffs.

The White House in the United States had hoped to boost domestic aluminum production capacity by 50% through import tariffs. However, with aluminum prices soaring and limited production increases, they have decided to instead "open up" high tariffs. According to a report by Bloomberg on the 20th, President Trump signed a notice that day, launching an incentive plan for primary aluminum production investment. Companies can receive a discount of about 25% on imported primary aluminum if they build, expand, or renovate aluminum smelting plants in the United States and receive government approval, halving the current tax rate.
