A practical guide for supply chain and logistics leaders who suspect their fuel surcharge has drifted from actual diesel cost, with a step-by-step method to test it, challenge it and rewrite it.
Part of the SmartBuyer Procurement Guide Series.
A fuel surcharge looks like neutral arithmetic, but it is a formula whose every input was chosen by your carrier: the index, the base diesel price, the trigger bands, how often it updates and which charges it applies to. Change any one of them and the number moves with no change in the price of diesel. A hard-won rate reduction can be clawed back through a wide trigger table within months.
This guide shows you where the gap opens between fuel cost and fuel billing: asymmetric lag, the surcharge base, double recovery and weak verification on ocean and air. It gives you a seven-step method to rebuild the surcharge yourself, quantify the difference and rewrite the mechanism, and it reflects what experienced freight procurement specialists do differently.
If any of these describe you, this guide will earn back its 15 minutes.
