Deputy PM and Finance Minister Ekniti says the government will raise excise tax on cars not produced in Thailand, because FTA deals rule out import tariffs. The rate is still under discussion, with clarity targeted for September and 3-4 months' grace for firms to adjust, so the rule would start in early 2027. Foreign carmakers that commit to local production may keep the current rate, while those that do not invest would have to repay the difference. Car dealers and parts suppliers should expect a softer market in the transition, and those in the EV or auto supply chain should check how the rule affects their orders and pricing.
