Carrying cash from Singapore to South Korea
Two separate rules apply to any cash journey: one where you leave, one where you arrive.
Do you need to declare?
Yes: and on both legs of the journey. Leaving Singapore, Immigration & Checkpoints Authority requires a declaration above SGD 20,000. Entering South Korea, Korea Customs Service requires a declaration above USD 10,000. The two rules are independent: satisfying one does not satisfy the other.
The two legs
| Leg | Limit | Form | Authority |
|---|---|---|---|
| Leaving Singapore | SGD 20,000 | CBNI declaration (via the Singapore Arrival Card or the official app) | Immigration & Checkpoints Authority |
| Entering South Korea | USD 10,000 | Traveler Declaration Form | Korea Customs Service |
The same declaration is required when leaving.
Below USD 10,000 in total means of payment, no permission or declaration is needed. Above it, report the amount on the Traveler Declaration Form and keep the Certificate of Foreign Currency Declaration you are given, it is what lets you take the money out again.
If you do not declare
Singapore: An offence under the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act 1992.
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
Singapore uses SGD; South Korea uses KRW.
