On 10 September 2026 the EV Policy Board approved in principle a restructuring of EV excise tax: vehicles with high domestic production and parts content would pay lower rates than fully imported (CBU) cars. The Thai Chamber of Commerce supports this but says the Local Content and Thai Content ratios and CBU import caps (volume and time) still need to be set clearly. Suppliers and SMEs in the auto parts chain should watch for these criteria before planning sourcing or investment. No change applies yet; the article gives no effective date or rates.
