There is other way what my friend used with his friend from USA... But Bitmain wouldn't do that.. They wouldn't risk getting import banned in certain country... Anyways it goes like this..
Friend from USA sent him 13 miners... he has scratched cases A LOT, and pour some dust on it, so it looks like old used gear... he only paid... HERE IT COMES.... 13$ VAT....yea..
OP it was possible to reduce tax while it was sent but now I have no idea why even do you think about that. It's very late and 100% impossible to avoid tax. But in future consider your loss and act differently, I can't say anything more.
