I think it safe to say that is one could buy a Porsche, a BMW, or Mercedes for less than THB2M, they might be selling more of them as well.
I think you implied that tariffs were the reason Chinese EV sales were not more robust in the US because of the 25% tariffs. Does that seem reasonable?
Say an imported Chinese EV sells for THB 1,000,000 ($28K) in Thailand and the manufacturer has a margin of 20%.
7% of that million is VAT, so say THB 970K, so accounting for the manufacturer's margin, the landed cost in Thailand is about THB 776K
With the 25% duty, the landed cost in the US in would be about THB 970K ($27.3K), plus one or two hundred in additional freight. How is it they can't compete?
They could also set up plants in the US and pay no duty, but then they would have to pay more in wages and to meet safety and environmental regulations.
