FedEx will change its dimensional weight calculation starting August 18, rounding up any fraction of an inch or centimeter, which may increase shipping costs and lead to more packages incurring additional surcharges. This adjustment aims to align dimensional weight measurements with current weight measurement practices, creating consistency. Alongside this, FedEx will raise its U.S. inbound processing fee from $1.50 to $2.50. These changes come amid broader pricing adjustments in the shipping industry, contributing to rising ground shipping rates.
