However, you can turn this on if you would like to include the surcharges in your customers' shipping estimates at checkout.

Please see Fedex's website for the entire list of potential surcharges.
General Carrier Ship Rates Settings
Default Weight - Set up a default product weight so that products which are missing valid weights will be assigned the amount specified here in ounces.
Handling Fee - Charge your customers a handling fee which will be added on top of the carrier shipping charge. This will be included in the shipping charge so your customer only sees one combined amount.
Max Weight Per Package - Set a maximum weight per package. If an order exceeds this weight then the carrier shipping charge will appear as $0. Each order is assumed to be one package in Sweet.
