Used in a long term copper supply agreement as a broad hedge reference when the contract does not need refined cathode price isolated from mill shape or wire cost. A buyer of one specific copper product should check whether the series for that product moves differently before relying on this blend.

The [affected portion] of the Contract Price shall be adjusted using US PPI — Copper and Copper Products (BLS series WPUSI019011), 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 copper PPI escalation clause compares a current-period Producer Price Index value for the copper 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. Clauses typically name the exact BLS series code, an averaging window, a publication lag, and a cap limiting the maximum adjustment.
