What this means for your clause

Appears in bulk fertilizer supply and distribution agreements between manufacturers and agricultural cooperatives. Natural gas is the dominant feedstock cost for nitrogen fertilizer, so a drafter sometimes pairs this with a natural gas index rather than relying on it alone to capture feedstock swings.

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 — Nitrogenous Fertilizer Manufacturing (BLS series PCU325311325311), 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.]
