WeightCountry Shipping for WooCommerce is a free WordPress plugin designed to streamline shipping calculations based on cart weight and specific countries. It integrates directly with WooCommerce, allowing users to set shipping rates according to predefined country groups. This plugin is particularly useful for businesses that sell to selected countries and need a straightforward way to manage shipping costs based on product weight.

However, it is important to note that the plugin has known limitations. It does not support shipping charges based on product categories or shipping classes, and it only provides one shipping rate per weight/country group combination. Additionally, it is essential for users to have their countries listed in the Specific Countries option of their selling locations for the plugin to function correctly. It has been tested with the latest versions of WordPress and WooCommerce.
