Perfect plugin to create customized shipping rules

This plugin creates a Validation Rules page in WooCommerce Shipping which allows you to create any sort of shipping rules you might need.

Our business has a category of products which cannot be delivered outside a certain zip code range, however, WooCommerce would still allow the transaction to proceed if there were other products in the cart which could be delivered anywhere. The Advanced Shipping Validation plugin solved that problem with a few simple conditions, and also allowed us to put up a message explaining to our customers why their transaction could not be processed.

On top of this being a tremendously useful and free plugin, the plugin author Jeroen provides excellent support.
