So I checked the prices around EU and the UK for the ZX500 series on Sony websites, it's around 800-850 EUR (VAT incl).
In JP the ZX707 is around 735 EUR (VAT incl).
I doubt the ZX700 will land in EU below the current/ launching zx500 price.
HTS for import is 8519.81, meaning 0 duty however VAT still applies (which for us is... a lot, 23% in my country, even the EU's lowest is 17%..).
This would bring the price to ~950 EUR for JP imported. Not that bad, given that it comes with *cough* uncapped volume.
Solutions:
Any e-shop + parcel forwarder (Buyee & Co): most probably double VAT (JP 10% + your state's tax), you have to deal with customs together with DHL/ FedEx/ etc (some handling fees, FedEx I see is around 15 EUR)
Amazon: Single VAT (your state's VAT), meaning that you won't pay the JP 10%, only the destination VAT/tax. Amazon handles the export/ import (DDP incoterms), you'll pick up the parcel hassle free.
Fly (to JP): hard sell, flight prices from the EU have skyrocketed since 2020... I'll be there in Q4, but I doubt I'll wait that long.
Best solution I see now is to wait for Amazon to list it as international shipping, as we won't pay the 10% JP VAT and we'll be left only with our VAT. Also, they do all import under DDP so it's completely hassle free (vs working with DHL/ FedEx or eww EMS/ Post which will req paperwork and stuff). This would cost, with 23% VAT incl, around 870 EUR
