I don’t think they are, and honestly I think it has to be a VIN that was actually manufactured for US market even then, but I’m not certain. Their USA site only lists one model and has no indication that you can buy it: https://www.byd.com/us/car/han-ev

Edit: some JDM forum guys claim you have to get it in writing from the manufacturer that the imported model is the same (or “substantially similar”) as the one sold here, for the purposes of not needing to re-pass safety testing. Which, good luck with that unless you’re Bill Gates (okay he actually ended up directly lobbying the government for a carve out for rare supercars, but still)
