Regardless of your shipping methods, you can apply restrictions. A restriction disables a shipping method for shipments to selected countries or regions. To apply a restriction, go to a shipping method and click the Restrictions tab. Then click and select whatever countries or regions you want to restrict.
You may want to disable a shipping method for certain locations. Follow these steps to limit a shipping method to specified countries:
From the Shipping Methods tab (Site Menu → Commerce → Settings → Shipping Methods), click on a shipping method and then on the Restrictions tab.
Click and check the box next to each country allowed to ship by this method. Click Add.
These restrictions apply to all shipping options for this method, but not to options of any other method.
To permit shipping to all countries, leave the restriction list empty.
