Thailand | Subsidies, duties, excise-tax incentives to encourage development and use of battery electric vehicles

  • The BEV 3.5 incentive policy represents the Thai Government's continuing push to drive development and transition toward zero-emission vehicles and to promote Thailand as the battery electric vehicle (BEV) production hub for the ASEAN region.
  • This policy offers a business operator subsidy; reduced duty and excise-tax treatment on BEV imports during 2024 and 2025 is available, provided the operator commits to commence local assembly of BEVs by 2026 or 2027.
  • This policy is limited to BEV passenger vehicles, pick-ups and motorcycles.

Executive summary

On 28 December 2023, the Excise Department unveiled rules, conditions and procedures outlined in the Thai Government's "BEV 3.5 policy," which will enable battery electric vehicle (BEV) importers and/or local BEV manufacturers to take advantage of a new set of subsidies and excise-tax reduction incentives for BEV passenger vehicles, pick-up trucks and motorcycles whether imported and locally assembled. The BEV 3.5 policy aims to encourage the development and use of BEVs in Thailand from 2024 to 2027.

Likewise, the Ministry of Finance (MOF) concurrently introduced its duty privilege policy and specified requirements for BEV imports for the period 2024 to 2025 under the BEV 3.5 policy.


In early 2022, the MOF and the Excise Department announced rules, conditions and procedures outlined in the BEV 3.0 policy, which grants subsidies and duty and excise-tax incentives for the period 2022 to 2025. Under this policy, businesses importing BEVs between 2022 and 2023 are eligible for these incentives if they commit to commencing BEV assembly in Thailand by 2024 or 2025. The key objective of this policy is to promote the development of the BEV manufacturing sector in Thailand and to leverage Thailand toward a carbon-neutral economy by 2050.

Now, the BEV 3.5 policy aims to further position Thailand as a production hub for BEVs in alignment with the Thai Government's 30@30 plan (which aims for BEV production volumes to constitute 30% of annual vehicle production by 2030) and to encourage the adoption of zero-emission vehicles. The Thai Cabinet has approved the BEV 3.5 policy for the period starting from 2024 to 2027.

  • The battery must have a capacity of 3 kWh or a range of 75 km on a single charge. It must also pass the Worldwide Harmonized Motorcycle Emission Certification tests/procedures with Class 1 or above, as certified by TAI.
  • The motorcycles must use pneumatic tires that meet one of the following standards:
  • Thai Industrial Standards Institute (TISI) standard no. TIS. 2720 ??- 2017 "Pneumatic [tires] for motorcycles and mopeds" or higher
  • The United Nations Regulation (UN Regulation) no.75 (00 series or higher).

Business operators that have signed up for the BEV 3.0 policy may transfer unsold BEV units imported under the BEV 3.0 policy to the new BEV 3.5 policy. However, to do so, the operators must also sign a memorandum of understanding with the Excise Department to comply with the BEV 3.5 conditions. Once the transfer is completed, the business operators can then claim the BEV subsidy amount provided under the BEV 3.5 policy when these BEV units are subsequently sold and registered with the Department of Land Transport.
