Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Nitrogen gas rose 3.2% over the last 12 months, but all of its main inputs rose faster: industrial electric power +4.2%. That cost pressure may still pass through to prices.

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 — Nitrogen (BLS series WPU06790303), 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.]
Prices on its own cycle from oxygen and argon despite sharing production infrastructure. Name the specific gas in the clause rather than citing a generic industrial gas index.
Divide the current value of BLS series WPU067903 (Industrial Gases) by its value at contract signing, then apply that ratio to the industrial gases part of the price. A usable clause also names an averaging window, a rule for revised values and missing months, and a cap.
Escalake tracks US PPI — Nitrogen, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
