What this means for your clause

Aluminum extruder and fabricator supply agreements cite this series when the contract buys a mix of mill shapes rather than one specific extruded profile, which WPU10250162 (Extruded Aluminum Shapes, Including Rod, Bar, and Wire) covers instead.

Draft a clause

A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.

The [affected portion] of the Contract Price shall be adjusted using US PPI — Aluminum Mill Shapes (BLS series WPU102501), 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.]

How this index is used

How do you calculate an aluminum price escalation clause using the PPI?

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.
