[Auto People] Thailand Electric Vehicle Consumption Tax Increased, Southeast Asia Trade Barriers Raised

Thailand plans to implement a tiered consumption tax on electric vehicles, and the automotive trade environment in Southeast Asia is shifting significantly.

In mid-October 2026, Thailand's Ministry of Finance released a proposal, planning to implement new rules for tiered electric vehicle consumption tax starting January 2027.

Specifically, for electric vehicle models with no local production arrangements that are directly imported as complete vehicles, the consumption tax will increase from the current 10% to not less than 30%. However, the proposal still needs to be submitted to the cabinet for review, and final implementation details still have a small margin for adjustment, but the policy direction is clear.

Thailand Tightens Electric Vehicle Policies

After the news came out, Chinese automakers had to start recalculating export costs and pricing ranges.

Specifically, this tax system is divided into three tiers based on the automaker's investment and local implementation status in Thailand: Automakers with factories in Thailand and meeting local component localization standards can continue to enjoy preferential low tax rates; Enterprises that have submitted a clear production schedule and are testing the market with a small number of imported models currently will apply to the middle tax tier; Brands with no implementation plans and relying on complete vehicle imports long-term will execute the highest tax tier.

It is worth noting that this adjustment concerns Thailand's domestic consumption tax, not import tariffs. Thailand relies on adjusting domestic tax systems to bypass tariff agreement constraints under the ASEAN Free Trade Agreement, thereby raising costs for pure trade models in a targeted manner and avoiding trade friction.

Thailand launched the EV3.5 support policy for the electric vehicle industry in 2024, this rule set is used to guide automakers to set up production capacity and raise local component localization standards. On June 30, 2026, the localization accounting rules were tightened. From this node, imported battery cells no longer count towards local component statistics, and the path for automakers to only import battery cells from overseas and pack them locally in Thailand to meet localization indicators is no longer feasible.

EV3.5 is also bound by a production offset mechanism. In 2026, for every 1 complete vehicle imported by automakers enjoying preferential treatment, they need to produce 2 vehicles locally in Thailand; in 2027, this ratio increases to 1 to 3. If automakers fail to complete the corresponding production tasks, the tax incentives received earlier will be reclaimed.

This tiered consumption tax proposal in Thailand is an additional tax burden constraint added on top of the EV3.5 localization assessment framework. The two policies form a progression, continuously compressing the living space for complete vehicle import models.

Data from Thailand's Department of Land Transport and the Industrial Federation shows that in the first seven months of 2026, newly registered pure electric passenger cars in Thailand reached 126,439 units, surpassing the full-year scale of 2025. Among them, 62.58% of pure electric vehicle models came from complete vehicle imports from overseas. Chinese brands hold nearly 70% of the local pure electric vehicle market share, MG, BYD, Wuling, and Chery are the brands with high local retail sales.

Trade structure dictates that Chinese export automakers bear the most direct cost pressure.

Thailand is a traditional automotive manufacturing hub in Southeast Asia. The automotive industry contributes about 2% of its GDP, and automotive exports account for 15% of Thailand's total exports. After the market opened to electrification, local electric vehicle terminal sales rose rapidly, but most of the incremental volume stayed at the sales end, while battery, core component capacity, and high-end employment remained overseas.

This tiered consumption tax proposal is not to limit electric vehicle consumption, but to use tax differences to screen manufacturers willing to invest in heavy assets, keeping the battery, component, and complete vehicle manufacturing supply chain in Thailand, and guarding its position as the Southeast Asian automotive manufacturing center.

Southeast Asia Trade Rules Tightening

Thailand's consumption tax proposal can be said to be another ring in the continuous tightening of policies in multiple countries in Southeast Asia in recent years.

Southeast Asia is the earliest overseas training ground for Chinese independent brand passenger cars. In the early years, Chery and Geely relied on geographical location and sea transport advantages to work out the whole set of models for CKD spare parts assembly and dealer channel construction. The channels and localized operation experience accumulated in Southeast Asia also became the foundation for subsequent Chinese automakers to expand into other overseas markets.

Looking at the overall Chinese vehicle export market, Southeast Asia is still a stable incremental sector for Chinese electric vehicles. In the first half of 2026 Chinese complete vehicle export destination list, the Philippines and Thailand stably entered the top ten; looking at the electric vehicle statistical category alone, Thailand, Indonesia, and the Philippines rank at the front for years.

In addition, Southeast Asia is also a mature RHD production capacity base. Produced models can be supplied to the Australia, New Zealand, and Commonwealth markets to share R&D and production line investment.

Looking at the entire Southeast Asian electric vehicle market, a clear tiered pattern has emerged. The market foundation of each country is different, and the industry development paths and policy orientations also differ.

Thailand belongs to the regional manufacturing hub, and is also the country where Chinese automakers have the most concentrated heavy asset implementation. BYD has built a large-scale complete vehicle production base in Thailand with an annual capacity of 150,000 units. Products cover local consumption and radiate to ASEAN and Australian markets; SAIC MG has deeply cultivated the Thai market for many years, maintaining a stable production and sales rhythm relying on local mature production lines; Great Wall Motor has acquired General Motors' idle complete vehicle factory area for renovation and production, successfully implementing local manufacturing capacity.

The automakers with implemented production capacity are less impacted by the consumption tax proposal. For brands that only import complete vehicles, the pressure will be directly manifested.

Indonesia and Malaysia belong to a group bound by resources and industry.

Indonesia holds nickel ore resources. The localization indicator of localization rate (TKDN) is rising year by year. The minimum is 40% in 2026, adjusted to 60% from 2027 to 2029, and the 2030 goal is 80%, aiming to open the closed loop chain of nickel, cathode, battery cells, and complete vehicles. Wuling's Cikarang plant in Indonesia started production as early as 2017. BYD has also laid out production lines in Indonesia. Pure complete vehicle imports have very little survival space here.

Malaysia ended the four-year tax-free period for electric vehicle complete vehicle imports on December 31, 2025. New regulations took effect in July 2026, setting a CIF price threshold of 200,000 Malaysian Ringgit (approximately 326,500 RMB) and a minimum 180kW motor threshold for imported electric vehicles. Low-priced imported models are basically kept out, guiding automakers to turn to spare parts assembly.

The Philippines is currently the most relaxed consumption market among major countries in Southeast Asia. There is no mandatory localization assessment, and it is also the single largest Southeast Asian country for Chinese complete vehicle export volume, with many trade orders concentrated here.

Vietnam is an independent closed-loop market. The local brand VinFast occupies the mainstream, supports its own charging network, and foreign brand expansion space is limited.

In the past few years, complete vehicle export was the preferred path for many Chinese automakers to enter the Southeast Asian market: complete vehicle manufacturing was completed domestically and then shipped, the model investment was light, the trial and error cost was low, and sales were opened up with cost-performance ratio. However, the continuously tightening localization regulations are gradually squeezing the profit space of this light asset model.

The overall demand for electric vehicles in Southeast Asia is still in the upward stage, and market penetration is lower than domestic, with significant long-term incremental space. However, consistent with the global trend in most regional trade, the dividend window for complete vehicle export is narrowing rapidly. In the long run, automakers who can stand firmly are mostly players willing to simultaneously implement the complete vehicle, battery, and component whole industry chain.
