Did anyone pay for the China custom tax when your miner broke down, and you ship it back for warranty repairs?
Kindly advise.
You should ask your tax office. The last time I had a repair in China, customs wanted to charge me the full tax amount again as the device came back.
They said I should have exported the device for repair purposes. They cannot distinguish between a new and a repaired device.
Thanks, +1 to this suggestion. OP when you unexperienced, it really sucks because such difficult situations can came like this person said and it will cause problems.
You don't have to pay them anything and you don't have to pay. Some people don't knows it and lies to customs by making antminer less visible like a new one.
