Foreign ownership

List 3: Restricted, FBL/BOI route availableinherited from 46

Wholesale of goods of all kinds, where 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 wholesaler is exempt from this List 3 item (no Foreign Business Licence needed) once minimum registered capital reaches the Act's threshold, typically THB 100 million per store. Verify current ministerial-regulation figures.

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.
