Yes. BOI eligibility does not impose a general Thai shareholding cap, so a wholly foreign-owned company can hold a promotion certificate. The exceptions sit in certain agriculture and service categories where other statutes require Thai majority ownership, so confirm your activity code before fixing the shareholder structure.
The general floor is THB 1 million in investment capital, excluding the cost of land and working capital. Selected high-technology activities set the bar at THB 50 million or more, and the exact figure comes from the announcement covering your specific activity code, so verify it before budgeting.
No. The current BOI regime no longer ties privileges to an export ratio, unlike certificates issued before 2014 where several categories carried explicit export conditions. Holders of legacy certificates should read their own conditions carefully before shifting sales toward the domestic market.
Projects of THB 200 million or less are usually decided in 60 to 90 days, while larger projects take 120 to 180 days because the full board must approve them. The clock starts only once the file is complete, so a well-prepared business plan is the single biggest time saver.
Failure to import machinery within 30 months, start production within 3 years, or relocating outside approved zones — card is revoked and back taxes plus penalties are collected.
