    AMU: Tariff whiplash as 50% taxes join the melt mix

    Written by Nicholas Bell


    Just when we thought we’d get a breather from tariffs news, especially after the recent court ruling limiting trade restrictions based on the International Emergency Economic Powers Act, we’re back in the thick of it.

    President Trump has announced his intention to double tariffs on aluminum imports to 50% effective June 4.

    AMU: Edward Meir’s week in review and thoughts for the week of Oct. 12, 2026

    Base metals had a mixed week. Tin lost almost 4% on the week, finishing at $53,000/ton. Prices dropped to a low of $51,259/ton at one point. Aluminum was another loser, off by about 1.6% on the week. Investors are expecting more aluminum supply going forward, especially out of China and Indonesia. Copper prices tacked on 1.1%. They have now recovered more than half of the $700/ton loss sustained (over the course of a week) following reports/rumors in mid-September that US tariffs on refined copper imports might not proceed after all.
