What this means for your clause
A narrow, named cut of the rubber and plastics hose and belting series. Use it specifically for belt drives, not the parent series, when the contract is belt-specific.
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 — Rubber and Plastics Hose and Belting Manufacturing, Transmission Belts and Belting (BLS series PCU326220326220D2), 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.]
Compare the current value of BLS series WPU0711 (Synthetic Rubber) to its value at contract signing, turn that into a ratio, and apply the ratio to the synthetic rubber-affected line items. A usable clause also names an averaging window, a publication-lag rule, and a cap.
