Primary aluminum smelter offtake agreements and long term ingot supply contracts cite this industry series, while a contract buying finished sheet or extrusion should use WPU102501 (Aluminum Mill Shapes) or WPU10250162 (Extruded Aluminum Shapes, Including Rod, Bar, and Wire) instead, since smelting cost and downstream fabrication cost move on different drivers.

The [affected portion] of the Contract Price shall be adjusted using US PPI — Alumina and Aluminum Production and Processing (BLS series PCU33131-33131-), published by BLS. Base Period: the index value published for August 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]

An aluminum PPI escalation clause compares a current-period Producer Price Index value for the aluminum series to the value at contract signing (the base period), turns that into a ratio, then applies the ratio to the contract price or affected line items. Clauses typically name the exact BLS series code, an averaging window, a publication lag, and a cap limiting the maximum adjustment.
