Foreign ownership

List 3: Restricted, FBL/BOI route availableinherited from 47

Retail sale of goods of all kinds, where the aggregate minimum capital or the minimum capital per store is below the level prescribed in the Act

Not a hard restriction — only applies while under-capitalised. A foreign-majority retailer is exempt from this List 3 item (no Foreign Business Licence needed) once registered capital meets the Act's minimum, typically THB 100 million in total and THB 20 million per store. Verify current ministerial-regulation figures.

FBA B.E. 2542, List 3 (14)Routes: Foreign Business Licence, BOI promotion, US Treaty of Amity

Auto-mapped, verify against the Act. These TSIC mappings are indicative, not legal advice; the schedules of the Foreign Business Act B.E. 2542 are the authority. See the full foreign ownership reference.
