Carrying cash from South Korea 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 South Korea, Korea Customs Service requires a declaration above USD 10,000. 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 South Korea | USD 10,000 | Traveler Declaration Form | Korea Customs Service |
| Entering China | max CNY 20,000 | Customs declaration form | General Administration of Customs of China |
Means of payment, foreign currency, Korean won notes or cashier's cheques, exceeding USD 10,000 in total must be declared on departure.
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.
If you do not declare
South Korea: Failure to report is subject to fines or penalties.
There is no limit on how much you may legally carry in either direction, the duty is to report it, not to keep under it. Failing to report is the offence.
Currencies
South Korea uses KRW; China uses CNY.
