On July 28, 2026, the Thailand Board of Investment (BOI) officially approved a new semiconductor investment incentive package aimed at attracting investment in the complete industry chain including wafer fabrication, packaging and testing, and chip design. According to the official announcement, eligible projects can enjoy up to 13 years of corporate income tax exemption, along with a package of convenience measures such as land ownership and work permits for foreign technical personnel. This is the most specific and aggressive industry incentive policy since the Thai government released the "National Semiconductor Development Strategy" in 2025, with a target of attracting total investment exceeding 500 billion baht by 2027.
Policy Details: Tiered Incentives Focusing on Manufacturing and Advanced Packaging
This incentive package adopts a tiered system, providing different levels of support based on investment category and technology content:
- A+ Level (Wafer Fabrication and Advanced Packaging): For wafer fabs of 8 inches and above, silicon carbide (SiC) and gallium nitride (GaN) compound semiconductor manufacturing, as well as advanced packaging and testing projects such as 3D packaging and fan-out packaging, provides 13 years of full income tax exemption, followed by 50% reduction for the next 5 years. Import duties on equipment are also fully exempted.
- A Level (Traditional Packaging/Testing and Materials): For mature process packaging and testing, lead frames, substrates and other material manufacturing, tax exemption for 8 years.
- B Level (IC Design and R&D Centers): Chip design companies and R&D centers can enjoy 5 years of tax exemption, with relaxed quotas for foreign engineers.
In addition, the BOI has set up a fast-track approval channel, reducing the application process from an average of 6 months to 2 months. For mega-projects with total investment exceeding 30 billion baht, the government can assist with infrastructure construction, including dedicated power grids and water supply systems.
Industry Background: Thailand's Semiconductor Foundation and Global Supply Chain Reorganization
Thailand has long been an important electronics manufacturing base in Southeast Asia, with deep accumulation in hard disk drives and automotive electronics assembly, but has long been absent in wafer fabrication and chip design. Currently, Thailand has about 30 packaging and testing plants, but most are old capacity and lack its own wafer fabs. As the US-China tech war intensifies, global semiconductor supply chains are accelerating relocation from China. Leveraging its stable political environment, infrastructure, and flexible BOI incentives, Thailand has become a hotspot for undertaking this shift. While Penang, Malaysia excels in packaging and testing, and Vietnam focuses on assembly and substrates, Thailand is attempting to carve out a place in wafer fabrication.
Notably, in 2025 Thailand signed the "Memorandum of Understanding on Semiconductor Supply Chain Cooperation" with the United States, receiving US technical transfer and talent training support. The latest BOI policy also explicitly states that it will prioritize projects cooperating with US, Japanese, and EU enterprises to establish Thailand's strategic position in the "friend-shoring" system.
Industry Interpretation: Three Core Logics for Investing in Thailand's Chip Industry
For global semiconductor investors, Thailand is currently at a critical turning point. The following are investment logics worth noting:
1. Policy Certainty and Cost Advantage
Thailand's BOI incentive package is highly competitive among ASEAN countries. Compared with Malaysia's 10-year exemption and Vietnam's 5-year exemption, Thailand's 13-year exemption significantly reduces early-stage operating costs. Meanwhile, Thailand's industrial electricity price is about $0.1/kWh, lower than Taiwan and South Korea, which is especially favorable for high-energy-consumption wafer fabs.
2. Downstream Demand Surge, Market Within Reach
Thailand is the largest automobile producer in Southeast Asia, and the EV transition is driving a surge in demand for power semiconductors and automotive MCUs. BOI data shows that in 2025, Thailand's automotive electronics semiconductor imports reached $12 billion, growing over 15% annually. Local production can not only reduce costs but also shorten lead times and avoid the impact of global chip shortages.
3. Industrial Cluster Effect Starting to Emerge
With the announcement of the BOI policy, several international manufacturers have indicated expansion or new plans. A major Taiwanese packaging and testing company (industry speculation points to ASE or Powertech Technology) is evaluating establishing an advanced packaging base near Bangkok; Japan's Renesas Electronics is also considering setting up an automotive MCU design center in Thailand. Once an industrial cluster forms, deep integration of talent and supply chains will further strengthen competitiveness.
Risks and Challenges: Technology Barriers and Talent Gap
Despite the optimistic outlook, Thailand still needs to overcome many challenges. Wafer fabrication requires a large number of experienced engineers and technicians. Currently, Thailand has fewer than 5,000 specialized professionals in the semiconductor field. India and Vietnam have also introduced similar policies recently, leading to fierce competition. Additionally, geopolitical risks cannot be ignored—if the US-China conflict intensifies, over-reliance on one camp could lead to sanctions. Therefore, the BOI deliberately emphasizes "neutral diversification" in policy design, welcoming investment from all countries while actively participating in the construction of a Southeast Asian semiconductor common market.
Conclusion: Why Now Is a Good Time to Invest in Thailand's Chip Industry?
Overall, Thailand is shifting from "passively undertaking capacity" to "actively building an ecosystem." The current BOI incentive package is not just tax relief but a comprehensive blueprint for building an industrial ecosystem. For investors interested in the Southeast Asian semiconductor market, now is the window of opportunity—clear policy dividends, an irreversible supply chain migration trend, and strong end demand. Of course, investors need to choose appropriate technology segments and cooperate with local partners or already-landed international manufacturers to mitigate risks. Thailand's chip dream is moving from policy to reality.
