Shipping classes can be used to group products of similar type and used by some shipping methods, such as Flat Rate Shipping, to provide different rates to different classes of product.
For example, with shipping classes and Flat Rate Shipping, it’s possible to create different flat rate costs for different product types, like bulky items and small items.
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.
