How it's built
Mining machinery rose 3.6% over the last 12 months, but 2 of its main inputs rose faster: hot rolled steel bars, plates, and structural shapes +15.0%, ball and roller bearings +5.0%. That cost pressure may still pass through to prices.

Key figures
- From Jan 2017 to Sep 2026 the index went from 263.5 to 462.3, a change of +75.4%.
- Highest reading in that period: 462.3 in Jul 2026. Lowest: 261.6 in Feb 2017.
- Largest one-month rise: +5.5% in Oct 2018. Largest one-month fall: -0.9% in Aug 2019.
- For a clause that resets its base every year, a 10% cap or floor would have limited the adjustment in 3 of the last 36 months.
Use it in a contract
Draft clause citing this series
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 — Mining Machinery and Equipment Manufacturing (BLS series PCU333131333131), published by BLS. Base Period: the index value published for September 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.]
Why contracts cite this index
The standard index for mining-specific equipment, distinct from general construction machinery, relevant to a mine development or extraction equipment contract.
