Setting Up a Factory in Thailand: The Step-by-Step FDI Blueprint

Thinking about launching a Foreign Direct Investment (FDI) manufacturing setup in Thailand? The process is highly rewarding but requires strict adherence to a specific legal timeline.

Here is your exact step-by-step master plan, from initial application to final tax exemption.

Phase 1: Corporate Foundation & Capital Setup

1. Apply for BOI Promotion: Before spending capital, submit your investment plan to the Thailand Board of Investment (BOI) to secure your tax and non-tax incentives.
2. Get Approved & Register: Once you receive the BOI resolution letter, incorporate your company. Under BOI privileges, you can register as a 100% foreign-owned company (bypassing the standard Foreign Business Act restrictions).
3. Open a Local Bank Account: Set up your Thai corporate bank account.
4. Inward Fund Remittance: Transfer capital from your foreign account into Thailand.

Important: Ensure the bank issues a Foreign Exchange Transaction (FET) form for every transfer—you will absolutely need this to prove your capital investment later.

5. Receive BOI Certificate: Submit your proof of company registration and capital to the BOI to officially collect your physical BOI Promotion Certificate.

Phase 2: Land & Construction Compliance

6. Secure Land Approval: Apply for BOI permission to legally buy and own land under the foreign company name.
7. Zoning & Permits: Verify the land is in an legally approved industrial zone (Purple zone).
   • If building fresh: Apply for a local municipal building permit (Aor. 1).
   • If renting an existing facility: Skip the building permit step.

Phase 3: Setup, Customs, & Industrial Licensing

8. Import Machinery via eMT: Use the BOI’s electronic eMT Online system to submit your machinery master list. This grants you complete import duty and VAT exemptions on your production line.
9. Secure your Factory License (Ror Ngor 4): Depending on your staff count and machinery horsepower, you may need a Ror Ngor 4 permit from the Department of Industrial Works (DIW).

Note: The Factory Act requires a full Type 3 Ror Ngor 4 license if your facility uses greater than 50 horsepower or employs more than 50 workers.

10. Environmental Permitting: Apply for your Environmental Hazardous Activities permit (and check if your specific industry triggers an Initial Environmental Examination (IEE) or full EIA).

Phase 4: Production & Supply Chain Activation

11. Start Production: Power up the facility and begin initial trial runs.
12. Import Raw Materials via RMTS: Utilize the BOI’s RMTS (Raw Material Tracking System) online platform to clear duties on incoming component parts and raw assets meant for assembly and export.
13. Export & Trade: Begin global distribution.

Phase 5: Ongoing Compliance & Tax Capping

14. Yearly BOI Reporting: Submit your mandatory annual performance and financial report to the BOI to ensure continuous compliance.
15. Year 3 – Full Commencement Verification: Within 3 years of certificate issuance, you must announce the Official Commencement of Operations. You will compile and submit a comprehensive audit of all project investment values:
    • Factory building construction costs / lease values
    • Machinery and tooling value
    • Office equipment and tech infrastructure
    • Initial corporate setup costs
16. The Final Tax Cap: After a rigorous site inspection and document approval, the BOI will determine your project’s final Corporate Income Tax (CIT) exemption ceiling based on that audited investment total.
