Largest one-month rise: +8.8% in Feb 2026. Largest one-month fall: -1.2% in Jun 2025.

What this means for your clause
The tighter of the two aggregate levels for this industry, cite this instead of PCU3344 (Semiconductor and Other Electronic Component Manufacturing, NAICS 3344) when the buyer wants the narrowest available bucket without naming a single product line. Still broader than any single product series, so a dispute over one product type needs one of those instead.
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 — Semiconductor and Other Electronic Component Manufacturing (NAICS 33441) (BLS series PCU33441-33441-), 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.
