You're mostly likely going to have to pay VAT and Import duty. For my BFL Miners into the UK I paid about 8% + 20% VAT. It's a fking rip-off I must say.

Let's say you buy a 60GH BFL miner @ $2200, you'll most likely have to pay another $600 in customs charges, which might make it even more expensive than renting from cex.io (and they deliver instantly).

Or, you could fly out to the US and try to smuggle your gear back into your country
