Shipping Class Based Shipping Rule
Shipping classes are used to group products – they are not used directly to offer shipping rates to customers. To set up shipping rates, configure Shipping Zones, and then add your shipping class costs to a shipping method, like Flat Rate.
This option allows a user to add extra cost based on shipping classes. It provides all shipping classes which are already used for the product. It displays all shipping classes list with a text box to add cost. The shipping class cost will be added to the shipping charge.
