Would they (the seller) even be willing to ship it to the US at all? I'd think warranty would probably be void. It would be subject to Customs of course, 8518.40 is duty free but user fees would be applicable and possibly brokerage fee depending on carrier utilized....believe it would be country of origin Vietnam so don't believe the punitive tariffs would apply (if China instead). Probably better to look for a US sale
ps Further look at the tariff/rulings 8527.91.6080 but still has no basic duty (depending on the China thing, didn't look that part up as pretty sure it's of Vietnam make).
