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 — Unsupported Plastic Film, Sheet, and Other Shapes (BLS series WPU0722), 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 plastics or resin PPI escalation clause compares a current-period Producer Price Index value for a named resin 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. BLS publishes separate series for thermoplastic resins, thermosetting resins, and finished plastic products, so naming the exact one matters more than usual here.
