Some carriers will also apply a surcharge for irregularly sized packages. Even if the Dimensional Weight of the package exceeds the actual weight, it might not be sufficient to adequately compensate the carrier for the overhead associated with moving an awkwardly sized package.
To address this scenario, some carriers will apply an Equivalent Oversize Weight when the package exceeds a certain size. For example, a carrier might set the oversize threshold at 84 inches, where Size is computed as being equal to Length + 2(Width + Height) and where Length is defined as the longest of the three dimensions. For any package where the Size is greater than the Oversize Minimum, the package will be rated using the Equivalent Oversize Weight, unless one of the other weights (that is, actual weight or Dimensional Weight) is greater than the Equivalent Oversize Weight.
To enforce oversize requirements, tariff charges used to apply weight-based rates to individual pieces support an Oversize Minimum and an Equivalent Oversize Weight. The former is not expressed in any of the UOMs supported by Transportation Manager while the latter is expressed in the tariff's Weight UOM.
These values are accessible only for tariff charges where the corresponding master charge is configured to use Weight as the (Rating) Unit Type, the Multi-Freight Class flag is False and the corresponding Data Accumulation Level is Container.
