What changes by where you expand from
Your home market shapes which entity route, treaty, and logistics setup makes sense. These are the patterns we see most often by region.
ASEAN Economic Community
ASEAN
Companies from Singapore, Malaysia, Vietnam, Indonesia, and the Philippines benefit from ASEAN Free Trade Area tariff reductions and simplified customs procedures. Regional supply chains already routing through Thailand make a local entity a natural extension rather than a new market bet.
Thailand is the largest recipient of Japanese FDI in ASEAN, with deep manufacturing and automotive supply chain integration. Japanese companies frequently pursue BOI promotion for manufacturing activities, benefiting from established industrial estate infrastructure and long-standing government relationships.
Chinese and Hong Kong companies typically enter through a standard Thai Limited Company or BOI promotion for manufacturing and e-commerce logistics activities, leveraging Thailand's position as an ASEAN distribution hub and China-Thailand Railway connectivity for regional trade.
Indian companies benefit from the India-Thailand Free Trade Agreement covering select goods, plus growing IT services and pharmaceutical sector interest. Many Indian founders use Thailand as a base to serve the broader ASEAN market while managing costs lower than Singapore.
US companies and citizens have a unique advantage: the US Treaty of Amity allows 100% ownership without BOI approval or a Thai partner. Canadian companies typically use standard Thai Limited Company or BOI routes, as Amity benefits are US-specific.
European companies most often pursue BOI promotion, particularly for automotive, food processing, and green/BCG economy activities aligned with EU sustainability priorities. Thailand's political and regulatory stability continues to draw European manufacturers relocating from higher-cost markets.
The Thailand-Australia Free Trade Agreement (TAFTA) has eliminated most tariffs between the two countries. Australian companies commonly enter through standard incorporation for services and trading activities, drawn by Thailand's cost base and time zone proximity for APAC operations.
Middle Eastern investors, particularly from the UAE and Saudi Arabia, are increasingly active in Thai real estate, hospitality, and BOI-promoted logistics and halal food processing, drawn by growing GCC-ASEAN trade ties and Thailand's tourism infrastructure.

Questions
Before you pick a corridor
01What is the best entity structure for a foreign company expanding to Thailand?
It depends on your home country and activity. US companies often use the Treaty of Amity for 100% ownership without BOI approval. Companies in technology, manufacturing, or BCG-aligned activities from any country typically pursue BOI promotion for tax holidays. Others use a standard Thai Limited Company, often with a Thai joint-venture partner.
02Do ASEAN companies get special treatment expanding into Thailand?
ASEAN Free Trade Area (AFTA) member companies benefit from reduced tariffs on goods trade, but company registration rules for foreign ownership are the same regardless of ASEAN membership — you still need BOI promotion, Foreign Business License, or a Thai majority partner to exceed 49% foreign ownership.
03Is Thailand a good alternative to Singapore for a regional headquarters?
Many companies use Thailand alongside or instead of Singapore for manufacturing, back-office, and regional distribution functions, due to lower operating costs and BOI tax incentives. Singapore often remains preferred for treasury and holding company functions due to its treaty network and financial infrastructure.
04How long does it take a foreign company to start operating in Thailand?
A standard Thai Limited Company can be registered in 7–14 days. Adding BOI promotion typically extends the timeline to 3–6 months due to activity approval. US Treaty of Amity setup takes roughly 6–8 weeks. Visa and work permit processing for relocating staff runs in parallel.
05Which industries get the most support for foreign investment in Thailand?
BOI prioritizes advanced technology, biotechnology, EV manufacturing, digital services, BCG (bio-circular-green) economy activities, medical devices, and value-added manufacturing — offering the longest tax exemptions and fastest visa processing for these sectors.
