Thailand Customs Currency Limits: Cash Import & Declaration
Bringing more than USD 20,000-equivalent in cash or bearer instruments into or out of Thailand triggers a mandatory Customs declaration under the Customs Act and Bank of Thailand exchange-control rules. Undeclared cash above the threshold can be seized.
TL;DR
Travellers entering or leaving Thailand with more than USD 20,000 (or equivalent) in cash or bearer-negotiable instruments must file a written customs declaration under the Customs Act B.E. 2560 (2017) and the Exchange Control Act B.E. 2485 (1942). The Anti-Money Laundering Act B.E. 2542 (1999) also requires AMLO notification above set thresholds. Undeclared sums above threshold are subject to seizure and prosecution.
What Counts as Reportable
- Foreign currency in cash (banknotes).
- Thai Baht in cash — limits also apply for outbound Thai-Baht movements.
- Bearer-negotiable instruments (bank drafts, traveller's cheques, bearer bonds).
Outbound Thai Baht
| Destination | Thai Baht cash limit |
|---|---|
| Vietnam, Laos, Cambodia, Malaysia, Myanmar (CLMV neighbours) | Up to THB 2,000,000 without prior approval |
| Other countries | Up to THB 50,000 without prior approval |
How to Declare
- Pick up the declaration form at the Customs red channel before passport control.
- Complete the form (source of funds, intended use).
- Submit at the Customs counter with the declared cash.
- Receive the stamped form for retention (commonly required to support large bank deposits afterwards).
Common Mistakes
- Using the green channel when above-threshold cash is on you — that itself is a violation.
- Splitting cash among travelling companions to evade the threshold (structuring) — separately prosecutable under the AML Act.
- Not declaring inbound bank drafts assuming "cheques don't count" — bearer-negotiable instruments do count.
FAQs

2. Can I bring in unlimited foreign currency?
Yes, but anything above USD 20,000-equivalent must be declared.
3. Does the rule apply to all travellers?
Yes — Thai citizens, foreigners, residents, transit passengers, all subject.
