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 — Jet Fuel (BLS series WPU057203), published by BLS. Base Period: the index value published for September 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.]
The standard index for aviation turbine fuel, relevant to an air charter, cargo, or defense logistics contract fuel escalation clause.
New aircraft are escalated with a labor and inflation formula, not a manufacturing PPI: 65% Employment Cost Index (manufacturing, CIU2013000000000I) plus 35% CPI-U (CUUR0000SA0), measured against base-year values and applied at delivery. Spare parts have no series built for them, so price them from a weighted input composite instead.
Escalake tracks US PPI — Jet Fuel, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
