    Wittbecker on Aluminum: The impact of tariff uncertainty and UBC tightness

    Written by Greg Wittbecker


    This week saw the aluminum industry gather at the S&P Platts Aluminum Symposium in Fort Lauderdale, Fla. The event normally draws a decent crowd because it is the first opportunity for the industry to exchange thoughts in the new calendar year. It also gives people a respite from the winter as it normally rotates between Florida, Arizona and California.

    There are two central themes that are worth focusing on this week: the impact of what at the time were Trump’s proposed tariffs and the tightness in used beverage container scrap. (Those tariffs – 25% on imports from Canada, 10% on imports from China – are now scheduled to go into effect on Tuesday.)

    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.
