Tira here from Shopify Support.
I would be happy to help you out here. What products are you selling and which countries are you looking to ship to? Could you tell me more about what it is you're looking to set-up for shipping when it comes to specific countries? Where are you located?
Thank you for getting back to me with more details!
Since you want to ship internationally, I recommend setting your shipping zones by following our help doc here: Shipping Zone Set-up. When selecting which countries to add, you'll want to select specific countries, or you can choose, "Rest of World" to ship internationally to all countries.
Who are you using for a shipping carrier? Or are you looking for a carrier to ship your electronic device?
