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 — Turbine and Turbine Generator Set Manufacturing (BLS series PCU333611333611), 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 defense contracts into aircraft, naval, land systems, missiles, and small arms. Aircraft (PCU336411336411), naval systems (PCU336611336611), and small arms/ordnance manufacturing (PCU33299T33299T) have real, published US government price indices. Land systems and missiles do not, confirmed by direct check against the BLS API. Build those two from a weighted input composite instead.
