Most shippers are aware that weight, zone and service level affect cost. But most are unaware that shipments are subject to accessorial charges which are additional charges not included in shipping cost. Accessorial charges are charged by carriers for package characteristics and value-added services that go beyond the normal pick-up and delivery requirements agreed upon at the time of purchase.
FedEx and UPS identify over 100 accessorial surcharges. The most common surcharges include, Dimensional, Fuel, Residential, Delivery area and Extended area.
