Reply from bitmaintech can be instant or sometimes it will take some time.
No no invoice is provided with the shipment and you can use the one available in the website.
In the shipping declaration unlike S1 and S2 they declared the full correct value in US dollar.
In declaration the product is described as "Bitcoin Miner". No customs issues.
They may call if some officers don't know what Bitcoin Miner is. Bitcoin is famous but mining thing is not so familiar to all.
allcoinminer, thank you for the reply!
It means that I have to pay 21% more (VAT) than US miners.
Guys, is there any EU state where you can import, say 2*S3, without VAT payment?
Is there any distributor/reseller of Bitmain in EU? I can't find any reasonable offer on EU Ebay segment.
