Thailand's Chamber of Commerce (ส.อ.ท.) has endorsed a restructuring of the motor vehicle excise tax framework approved by the National EV Policy Board. The initiative aims to use tax incentives to attract real investment and domestic production, while strengthening the supply chain by connecting major automakers with SMEs and component suppliers. During the first seven months of 2026, BEV registrations reached 127,000 units (up 88%), and BOI has promoted 189 EV-related projects worth ฿151 billion. This tax restructuring directly targets SME integration into Thailand's auto supply chain, which currently supports 2,500+ companies and 800,000+ workers, representing over 10% of national GDP.
