Platts proposes new daily Aluminum P1020 Americas Duty-Unpaid Premiums Basket

Platts, part of S&P Global Commodity Insights, proposes to launch a new daily Americas duty-unpaid premiums basket for P1020 aluminum, using a combination of existing Platts duty-unpaid price references for Canada, the US, Mexico and Brazil, effective April 21, 2025, and backdated to March 3, 2025.

Market feedback in response to the introduction of new tariffs for aluminum imports into the US has demonstrated the need for a duty-unpaid calculation that incorporates multiple Americas pricing locations, while still having a link to the US Midwest.

The new Aluminum P1020 Americas Duty-Unpaid Premiums Basket (Americas DUP) would be a calculated simple average (arithmetic mean) of the following Platts P1020 duty-unpaid premium assessments, published in $/mt with a cents/lb conversion:

*The MW US Transaction Premium (Implied Duty Unpaid) delivered US Midwest assessment reflects Canadian-origin material.

**The latest value of this weekly assessment would be reflected in the daily basket calculation.

The proposed Americas DUP calculation would be backdated to March 3, 2025, the first publication date of Platts recently launched CIF Mexico P1020 Aluminum Premium assessment.

Monthly averages also would be published from March 2025, in both $/mt and cents/lb.
