Hong Kong has very few component production companies or assembly factories and where the major production of sub assemblies and final assembly occurs is what matters. In other words most of Bitmain miners are Made In China. Not sure if BM still runs any Malaysian factories that they used to get around the tariff regulations.
Yer just going to have to wait and see.
Units arrived today, after I was contacted by UPS yesterday. And the answer is..... YES. I did have to pay the 25% tariff.
