I buy stuff from Ebay all the time, even from places in the states that are the farthest from me. It just depends on how the sender sends the items, they can send with the full price value or they can mark it down. Most companies in the US who sell stuff over the internet either mark the price down or charge you the tax, if they charge you tax it costs you nothing when it gets to your door.
So really it depends on the company who's sending it.
Unfortunately I can't recoup the $12k plus the $2100 for duty and taxes and I am not about to take a loss on a brand new product, so I will take the risk. I have already informed KNC Miner so they are aware and kept in the loop.
I do sincerely wish you good luck with the refund.
Still, I was talking about shipments overseas. US to Canada and vise-verse is easy, as a lot of US and CA companies do that and have experience. But ask a US company to estimate customs charges to EU, or China, or Middle East. Or ask a EU company to estimate customs tax to anywhere outside of EU... There are 193 UN recognized countries... It's simply impossible (or rather very expensive for a company to research) until you, as an end-user, get the bill

EDIT:
I'm not defending KNC in any way (not after the wait the forced me to endure), all I'm saying is that for any such equipment it would be good to ask how it is being declared at customs and do research for your country on how much you're expected to pay for import. It's not directed at you, it's generic advice for all our miner buddies out there
