Its not arguing the classification, that is the correct one. It is the filing and pressure of the exclusion to the 25%.
The 25% one is really tough. But europe has been doing Vat at 17 to 21% for years.
Bottom line it will be interesting to see how it plays out.
I think China blinks then does some concessions to US and tariff ends in under 6 months.
For your business it is difficult. It leaves you with only GMO and and Triple-1 to source asic miners.
