FedEx to Price All Large Packages Based on Size - Fox Business FedEx (FDX) will soon charge rates for all large packages based on their size, effectively raising prices for lightweight, bulky ground shipments. The shipper unveiled the change on Friday in a little-noticed announcement. The memo also said FedEx’s fuel surcharge will be hiked by three percentage points on June 2. FedEx plans to apply dimensional weight pricing, which takes into account a package’s volume, to all shipments beginning Jan. 1, 2015. FedEx currently uses the size-based pricing method for packages that measure at least three cubic feet. Other shipments are priced only according to their weight.
