TSIC 2009 · Kingdom of Thailand

Thailand Standard Industrial Classification

The register of economic activities behind every Thai company registration. Look up a code to see what it covers, in English and Thai, and whether the Foreign Business Act restricts foreign ownership of that activity.

Foreign Business Act B.E. 2542

Which activities are restricted for foreigners?

The Foreign Business Act closes some activities to foreign majority ownership outright and gates others behind Cabinet permission or a Foreign Business Licence. Every TSIC code page on this site shows the restrictions mapped to it; the full three lists live on one citable reference page.
