UPS today released new list rates for 2010, including an average increase of 4.9 percent for UPS Ground packages and an average net increase of 4.9 percent on all air express and U.S. origin international shipments.

The rate increase for air express and international shipments is based on a 6.9 percent increase in the base rate, less a 2 percent reduction in the air and international fuel surcharge index.

Updated rate and service information will be posted on ups.com/rates beginning Nov. 20. On Dec. 18, customers can download the 2010 Rate and Service Guide. The new rates take effect on Jan. 4, 2010.

Also effective Jan. 4, fuel surcharge tables for air express and ground services will be adjusted. The changes will better align Air and Ground Fuel Surcharges and will substantially reduce the volatility of air surcharges when fuel prices fluctuate.

An explanation of the fuel surcharge calculation methodology along with the new rate tables will be available on ups.com/rates.
