What this means for your clause
Indexes the bare board substrate itself, separate from the populated assembly. A contract that only cites a chip index misses the board substrate cost, which moves on its own schedule.
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 — Bare Printed Circuit Board Manufacturing (BLS series PCU334412334412), 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.
Escalake tracks US PPI — Bare Printed Circuit Board Manufacturing, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
