My very limited experience is that if the machine was built and sold with a serial number by an american company , I would think their would be no import tax. With the dollar exchange rate, cost of shipping, and time thru U S Customs along with the boarder closing due to the Covid, their must be a sweet deal of the price? Again if made off shore and sold around the world by many companies then their is very likely to be a tax and the vendor should tell you that over the phone.
