I'm not 100% sure about what you mean. Do you mean to have multiple costs for one product? Or do you mean to just make sure your costs are covered based on the difference in shipping prices to different places?
If you could elaborate a little further on what exactly you mean it would greatly be appreciated and hugely helpful to perhaps finding a solution or giving you an answer to what you're looking for.
Looking forward to hearing from you.
All the best, Nick
Each product you sell can only have one price. You can adjust the price if you wish, but it wouldn't be possible to have one product with more than one cost.
Shopify does have a helpful guide about price-setting strategies which could be worth your time looking into and which you can read here. There is one section of the guide which I think is the most relevant to you which I screenshot and you can see it below:
