GSO uses index-based fuel surcharge calculations that are adjusted monthly for both GSO Priority Overnight and GSO Ground Services. Changes to the fuel surcharges will be effective on the first shipping day of every month.
Priority Overnight Fuel Surcharge
The fuel surcharge for GSO Priority Overnight (PDS) delivery services is based on the average "California On-Highway Diesel Fuel Prices" as reported by the U.S. Department of Energy for the four weeks prior to the adjustment.
Ground Fuel Surcharge
The fuel surcharge for GSO Ground (CPS) service is based on the National U.S. Average On Highway Diesel Fuel Prices reported by the U.S. Department of Energy for the month that is two months prior to the adjustment. For example the surcharge for January 2011 is based on the November 2010 National U.S. Average On Highway Diesel Fuel Price.
