Reading from Arizona, the temporary window (Nov 1 through Mar 31) is the part that stands out to me rather than the headline number. A 0% excise rate for roughly five months can shift retail prices, but the post is right that the actual drop depends on world prices and the pricing cycle, so the 1,500–1,700 figure is an estimate rather than a guarantee. I am curious whether Vietnamese consumers see the full pass-through at the pump or whether other cost components absorb part of it.
