    Tariffs are easy to announce, but hard to track

    Written by Gabriella Vagnini

    Announcing tariffs is easy. Implementing them at the border? That’s a whole different ball game.

    Customs runs all of this through their Automated Commercial Environment, better known as ACE. It’s their system for processing imports, flagging issues, applying duties, and pushing out updates. It sounds clean on paper, but when new tariffs get added, especially when they’re messy and product-specific like aluminum derivatives, it takes more than just flipping a switch.

    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.
