Use it in a contract

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 — Nonmetallic Abrasive Products (Including Diamond Abrasives) (BLS series WPU113603), 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

Used in consumables supply contracts for fabrication shops, foundries, and finishing operations. It has not followed steel prices, so a consumables clause tied to a steel series is likely to track the wrong thing.

How this index is used (1 guide)

How do you calculate an abrasives price escalation clause using the PPI?

Divide the current value of BLS series WPU113603 (Nonmetallic Abrasive Products (Including Diamond Abrasives)) by its value at contract signing, then apply that ratio to the abrasives part of the price. A usable clause also names an averaging window, a rule for revised values and missing months, and a cap.
