There isn't currently a way to automatically adjust the shipping rate for out-of-state/international orders, unfortunately. I definitely know that would be useful for sellers like yourself. 

As a workaround, you could create a modifier set that allows for the customer to select if their order is in-state, out-of-state, or international, and have that modifier adjust the price of the item accordingly. This of course puts some responsibility on your customers to select the appropriate shipping, but hopefully helps. 

Hopefully this is something we offer in the future! In the meantime I'll share your post with the team that works on the online store.
