§3What it means for an index clause
A pallet bought at $10.00 twelve months earlier, escalated in full with this index, would be $10.59 in August 2026. Method: $10.00 × (index in August 2026 ÷ index twelve months before). Most clauses only move the price when the change passes a band, and some pass through only part of it.
Under the model clause's quarterly review, which compares the index for the second month before each quarter with the base, the August 2026 reading is the one used for the review on 1 October 2026. It is still preliminary, so the clause's publication-date rule decides which value counts.
Run your own numbers with the escalator, or read the model escalator clause.
§4Freight context
U.S. retail on-highway diesel averaged $5.462 a gallon across 5 weekly EIA readings in August 2026 (+45.9% on a year earlier). Delivery charges and fuel surcharges are separate from the producer index, so price them as their own lines in the bid-leveling sheet.
