Legal Basis
Customs Act B.E. 2560 §112–120 (appeals) · WCO HS Convention · GIR 1–6 · WTO Valuation Agreement 1994 · Customs Department Notification 60/2561 (advance ruling) · Criminal Procedure Code (if penalty case).
Who Needs This
Importers/exporters, freight forwarders, licensed brokers, MNCs facing post-clearance audits, assessment-notice recipients.
Required Documents
- Import Declaration + commercial invoice + packing list
- Product catalogue + technical spec + material composition
- Mill certificate + laboratory test report
- Assessment notice / re-classification memo
- Comparable rulings abroad (US CROSS, EU BTI, HK CTA)
- Transaction-value evidence — arm's length + no royalty adjustment.
Common Pitfalls
- Strict 30-day appeal window from receipt of assessment · missing it makes the order final.
- GIR 3(a) 'most specific' beats GIR 3(b) 'essential character' · wrong order of argument loses.
- Royalty + assists + selling commission must be added to transaction value (WTO Art.8) · omission = under-declaration + 4× penalty.
- Advance rulings bind only the requesting importer · not retroactive to past shipments.
Typical Use-cases
- Electronics importer · re-class from HS 8471.30 (laptop 0%) → 8517.62 (transceiver 5%) · THB 12M saved at Tax Court.
- Cosmetics · royalty-inclusion valuation dispute · WTO transaction value defended · THB 8M refund.
- Auto parts · JTEPA origin denied · re-classified + FTA restored · 22% duty saved.
- Food supplement · 3-year post-clearance audit · settled at 30% of assessment.
FAQ

Frequently asked questions
- Can a foreigner own 100% of a Thai company?
- Generally no for activities listed in the Foreign Business Act, where majority foreign ownership requires a Foreign Business Licence, a BOI promotion, or treaty rights such as the US–Thailand Treaty of Amity. Manufacturing and certain export activities are largely open, and BOI-promoted activities can permit full foreign ownership together with land-holding and visa privileges, so the right structure depends on the specific activity.
- What is the minimum registered capital for a Thai company?
- There is no general statutory minimum for a Thai-majority company, but practical thresholds apply: THB 2 million of paid-up registered capital per foreign work permit, or THB 1 million if the foreigner is married to a Thai national, and THB 3 million per foreign shareholder for a Foreign Business Licence. Capital should therefore be planned around the visa and work-permit outcome you need, not the incorporation minimum.
- How long does company registration take?
- Registration at the Department of Business Development can be completed within one to three working days once the name reservation, shareholder documents and company objectives are ready, and the VAT registration and social security registration follow afterwards. The realistic end-to-end timeline including bank account opening is two to six weeks, with the bank account usually being the slowest step for foreign directors.
- What ongoing accounting obligations does a Thai company have?
- Every Thai company must keep statutory accounts, file monthly withholding tax (PND 1, 3, 53) and VAT (PP 30) returns by the middle of the following month, file the half-year corporate income tax return (PND 51) and the annual return (PND 50), and have its financial statements audited by a Thai CPA and filed with the DBD each year. Dormant companies are not exempt — nil returns and an audited statement are still required.
