Hi there!

Thanks for your question.

The best starting points would be the following help pages: Amazon Global Selling and Global registration. On the left hand side of these pages you will see additional help pages regarding Global selling.

Another section I would bring your attention to is in relation to global customer support. On the left hand side of the following page there are a number of additional links to help with this: Customer support and returns for international sales.

If you do decide to sell globally it's also important to ensure you will get paid and this help page will give you some more information: Payments for global accounts.

I hope you find this information helpful.
