Oof!! This one is kind of difficult...
These are my thoughts: I would suggest contacting your Post Office, ask them if they have any kind of a chart - or better, a website - where you could seek rates world wide. Also find where you can find a list of no-ship countries, or those with odd restrictions on shippable products.
Try to pick the most common weight range of products - say, up to 10 pounds - then compare freight rates to all kinds of places - bottom half of South America, pick an average cost; top half, same; Mexico, Central America, India, Phillipines, Europe, Great Britain....
Try to calculate an estimated price for each region from all your choices, then calculate the AVERAGE rate for all.
Now you need to decide if you ship free (you pay), or customer does.
On all your products, list "no shipping fees", or list your flat rate shipping charge to all points.
If the average price is high, I would recommend you split the shipping charges, both parties paying half. In this way, all customers pay half, and overall, hopefully, you will end up breaking close to even on the freight. Monitor the charges for a while, see how it goes, then you may need to raise the freight a little if you are paying more than half overall.
I'm not sure how much of a task this would be, but best I can think of for now.
Hope the thoughts are helpful:))...
