Carrying cash from Thailand to China
Two separate rules apply to any cash journey: one where you leave, one where you arrive.
Do you need to declare?
Part of this route is a hard limit, not paperwork. Leaving Thailand, Bank of Thailand (exchange control) caps what you may carry at THB 50,000, a prohibition, not a form. Entering China, General Administration of Customs of China caps what you may carry at CNY 20,000, a prohibition, not a form. The two rules are independent: satisfying one does not satisfy the other.
The two legs
| Leg | Limit | Form | Authority |
|---|---|---|---|
| Leaving Thailand | max THB 50,000 | no form | Bank of Thailand (exchange control) |
| Entering China | max CNY 20,000 | Customs declaration form | General Administration of Customs of China |
Thai baht banknotes may be taken out up to THB 50,000 per person, rising to THB 2,000,000 for travel to Cambodia, Laos, Malaysia, Myanmar, Vietnam and the Yunnan province of China. Foreign currency banknotes may be taken out only up to the amount bought from an authorised bank or money changer. A customs declaration is required above THB 450,000 or USD 15,000 equivalent.
The renminbi limit is a hard cap in both directions, carrying more than ¥20,000 in cash is prohibited, not merely declarable. Foreign currency has no quantitative limit, but cash worth more than USD 5,000 must be declared on arrival.
Currencies
