Hello Guys,

I have a control board issue with my Antminer L7 and after discussion Bitmain told me to send back the miner to China.
Its the first time I come along with the process to send back a miner to China and I have some doubts :

After Bitmain repair and send me back the miner will I have to pay again for customs taxes when they return it to me?
If yes, how to avoid the payment of taxes again?
What do you advise me in your experience to make the shipping secure and to avoid stealing and/or damages during shipping process?

Thanks in advance for your precious help guys !
