Hi @wlaschmidt ! I have a bit of experience with this that might be useful for you. One way to get your products onto Amazon in all countries is to use the Kindle Direct Publishing platform to create Print-on-Demand paperbacks. That way you don’t have to send inventory to Amazon at all – they will print and distribute it for you.
Global registration is an option if you need a more traditional seller account where you handle all the inventory. I don’t have any experience in this side of things, but if you look at How to Sell on Amazon | Amazon Seller University and scroll down to Global Registration, you should have enough information to start with.
Unfortunately Amazon sometimes limits access to its programs based on which country you’re in, so I’m sorry if the information above doesn’t work for you.
