The first-of-its-kind incentives, established under President Joe Biden's Inflation Reduction Act (IRA), will offer tax credits of $7,500 or $40,000 depending on the size of the electric vehicle (EV).
The IRA's commercial EV credits do not have "made in the USA" rules that apply to passenger cars.
That will "help level the playing field for electric vehicles," said Ben King, associate director at Rhodium Group, a research firm.
Jim Farley, chief executive at electric van market leader Ford Motor Co (F.N), this year predicted that IRA tax credits would have a "dramatic impact on the adoption of EVs."
More commercial EV purchases should lower manufacturing costs and vehicle sticker prices - which should attract even more buyers, experts said.
