Does the plugin add a fuel surcharge to the rate given by UPS?
Does your plugin add a fuel surcharge to the rate given by UPS? It looks like 5% is being added.
XAdapter Support :
Our plugin does not add any fuel surcharge to the rates returned by UPS. UPS sends the rates along with the fuel surcharge in the response. If you analyze the response sent by UPS, you will find a field for the same which contains a specific value. We are not able to confirm whether it is 5% all the time.
