Is this the price I pay at the supplier?
No. The Producer Price Index measures what domestic producers receive, before distribution and retail markups. Supplier and retail prices tend to follow it with a lag. Use it for the trend and for escalation, and get today’s number from your supplier’s quote.
Can I use this index in a price escalation clause?
Many contracts tie material escalation to a named Producer Price Index series, measured from the bid month to the purchase month. This page uses BLS series WPU1311 for flat glass. Name the exact series and months in the contract, and have your attorney review the clause.
