In the right hand column of the subscriptions detail page, you will see a customer block, with the shipping address of the subscription. You can edit this address, pick one from the existing addresses saved for that customer, or add a new one, from the modal that is triggered from the shipping address section.
You'll then be asked to confirm the shipping price, since often changing a shipping address can impact cost of shipping. You'll be able to select the calculated rate, or set your own custom one.
