Key figures
- From Jan 2017 to Sep 2026 the index went from 252.4 to 406.1, a change of +60.9%.
- Highest reading in that period: 406.1 in Mar 2026. Lowest: 252.4 in Jan 2017.
- Largest one-month rise: +11.0% in Mar 2018. Largest one-month fall: -4.3% in Jul 2018.
- The year-over-year change stayed within 10% either way in each of the last 36 months, so a 10% annual cap or floor would not have been reached.

Draft clause citing this series
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 — Structural Clay Products, N.E.C. (BLS series WPU1345), 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.]
Why contracts cite this index
