Key figures
From Jan 2024 to Aug 2026 the index went from 58.4 to 49.3, a change of -15.7%.
Highest reading in that period: 59.1 in May 2024. Lowest: 49.3 in Aug 2026.
Largest one-month rise: +1.6% in Mar 2025. Largest one-month fall: -5.7% in Aug 2026.
For a clause that resets its base every year, a 10% cap or floor would have limited the adjustment in 1 of the last 20 months.

What this means for your clause
Fits a wafer or discrete-component supply contract that needs to isolate device-level pricing from the broader mix of packaged chips the parent series tracks. Cite this alongside the parent semiconductor and related device manufacturing series only when the contract explicitly separates discrete devices from finished chips, otherwise the parent series alone is simpler to administer.
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 Related Device Manufacturing, Other Semiconductor Devices (BLS series PCU334413334413A), 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.
