For May 2018, the CASS Index, which is being used to monitor and evaluate U.S. Inland rates monthly, reflected an average of 133.7 for Truckload and 141.1 for Intermodal (rail). As a result, tariff and contract motor and Intermodal (rail) rates will not change. The CASS Indexes can be found here.
For the same period, the Department of Energy’s retail on-highway diesel prices all types index monthly average, which is being used to determine the Intermodal Fuel Charge, was $3.244. Therefore, the Intermodal Fuel Percentage will be increased from 24.5% to 26.5%, effective August 1, 2018. The requirements and index history are available here.
The next review is set for July 2018 after which an appropriate adjustment will be made if necessary.
