What this means for your clause
Covers finished battery packs and cells broadly. For EV or grid-scale battery-metal exposure specifically, pair with a lithium or nickel index rather than relying on this alone.
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 — Battery Manufacturing (BLS series PCU335910335910), 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.]
Split chips from the equipment that makes them. Chip prices index to BLS PCU334413334413 and move in sharp boom-bust cycles. Fab equipment indexes to PCU333242333242 and moves on a steadier capital-spending cycle. A shared index will misprice whichever side is not actually in its cycle phase.
Unlike steel or aluminum, lithium and battery metals have no single official government price index. Clauses instead reference a named private benchmark (commonly a Fastmarkets or Benchmark Mineral Intelligence lithium carbonate assessment, or an exchange settlement price) with the USGS annual average as a lower-frequency audit backstop. The ratio-and-adjustment mechanics are the same as any other escalation clause; naming the exact benchmark provider and price basis matters even more here.
