Key figures
From Jan 2024 to Aug 2026 the index went from 214.3 to 235.4, a change of +9.8%.
Highest reading in that period: 235.4 in Mar 2026. Lowest: 214.3 in Jan 2024.
Largest one-month rise: +9.8% in Mar 2026. It did not fall month to month in this period.
The year-over-year change stayed within 10% either way in each of the last 20 months, so a 10% annual cap or floor would not have been reached.

What this means for your clause
Used in pistachio supply and processing contracts on the same basis as WPU01190102 (Almonds). California accounts for nearly all US pistachio production, so a single bad-weather year can move this index sharply, which a contract's cap and floor terms should anticipate.
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 — Pistachios (BLS series WPU01190106), 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.]
A food or agricultural escalation clause compares a current-period Producer Price Index value to the value at contract signing (the base period), turns that into a ratio, then applies the ratio to the contract price. BLS splits raw farm commodities (Farm Products, WPU01) from processed food inputs (Processed Foods and Feeds, WPU02); picking the wrong one indexes the contract to the wrong stage of the supply chain, and the series is unusually seasonal, which makes base-period selection especially important.
