@zeynel thank you for the tip, I have a runnign business registered for EU vat and visible in VIES database. It seems I need to obtain this EORI number. I have used ebay GSP few times but business cannot reclaim these additional charges when it goes through GSP.
Do you provide this to ebay (somewhere in the complex maze of forms) and they deal with all the issues ?
