Before starting the operation, thorough preparation is key to ensuring successful remittance. This can help you avoid unnecessary delays due to incorrect information or insufficient funds. The entire ICBC USD to OCBC remittance process begins with these three simple preparation steps.
You first need to confirm your remaining personal foreign exchange purchase quota for the year. According to regulations from the State Administration of Foreign Exchange (SAFE), the personal convenience foreign exchange purchase quota for Chinese residents remains unchanged.
Core Policy: In 2025, each Chinese resident individual has an annual quota equivalent to $50,000 USD for foreign exchange purchases. Within this quota, purchases typically do not require additional supporting documents.
You can check your available quota through the ICBC mobile app or by visiting a branch.
Accurate recipient information is the cornerstone of successful remittance. Please prepare the following USD account recipient details for OCBC Bank in Singapore in advance and verify them carefully. We recommend saving this information in your phone’s notes for easy copy-paste during remittance to prevent manual input errors.
| Information Category | Details |
|---|---|
| Recipient Bank Name | Oversea-Chinese Banking Corporation Limited |
| SWIFT Code | OCBCSGSGXXX |
| Recipient Name | Your name in pinyin (consistent with OCBC account opening) |
| Recipient Account Number | Your OCBC USD account number (usually ending with USD) |
| Recipient Address | Your address registered with OCBC |
| Bank Address | 65 Chulia Street, OCBC Centre, Singapore 049513 |
Tip: When filling in the recipient account, ensure your OCBC USD account number format is correct, for example
501123456201USD.
Please prepare sufficient RMB in your ICBC account based on the planned USD remittance amount. It is recommended to prepare extra funds to cover fluctuations in the real-time exchange rate during purchase and possible fees.
When purchasing foreign exchange, you need to select a “purpose of purchase”. For transfers to your own overseas account, choosing “private tourism” or “family support” is common, typically requiring no additional proof within the annual quota.

After completing preparations, you can proceed to the actual operation phase. This section is the core of the entire ICBC USD to OCBC process. You will complete purchase and remittance in two steps via the ICBC mobile app. Please follow the detailed instructions below to ensure accuracy at every step.
Before remitting USD, you need to exchange RMB in your account into USD. This process is called “foreign exchange purchase.”
Important Note: The fund purpose selected during purchase should be consistent with the purpose filled in the subsequent cross-border remittance to ensure smooth processing.
Once you have USD in your account, you can start the ICBC USD to OCBC remittance operation.
First, locate the cross-border remittance function in the ICBC app. The navigation path is clear:
Homepage -> Transfer and Remittance -> Cross-Border Remittance -> Remittance to Overseas Other Banks
After entering the remittance page, fill in all information sequentially as prompted.
OCBCSGSGXXX.Remittance Processing Time Note After submitting your ICBC USD to OCBC remittance instruction, the bank does not process 24 hours. ICBC’s system processes remittance instructions in real-time on business days from 9:00 to 16:00. If submitted after 16:00 on Friday, the bank will start processing on the next Monday at 9:00. Therefore, to arrive faster, complete operations before 16:00 on business days.
After submitting the remittance application, the process is not entirely complete. You still need some simple follow-ups to ensure funds arrive safely and on time in your OCBC account.
After submission, your primary concern is the fund’s progress. You can check the real-time status of this remittance anytime through ICBC mobile banking.
Track Your Funds ICBC utilizes advanced SWIFT Global Payment Innovation (gpi) technology. This system makes cross-border payments more transparent. You can track each step of the remittance in real-time, just like tracking a package, clearly seeing which bank is currently processing the funds.
Simply find the transaction in the app’s remittance records, click for details, and view the latest progress.
Next, wait for the funds to arrive.
Based on most users’ experiences, remittances from ICBC to OCBC Bank in Singapore typically arrive in less than 2 business days.
When you see the credit notification in your OCBC mobile app, carefully verify the received USD amount. If you selected Remitter Bears All fees during remittance, the received amount should theoretically match your remitted amount exactly.
Cross-border remittances incur certain fees. Understanding the fee structure helps you better manage costs. ICBC USD to OCBC fees mainly fall into two categories:
Important Note: All fees are based on the amount displayed on the app’s final confirmation page when you pay.
In addition to traditional bank channels, new remittance options have emerged. For example, some digital payment platforms Biyapay offer alternative fee models. They may not charge proportional commissions but a fixed service fee per transaction. For large remittances, this can sometimes be more cost-effective. Before remitting, compare total fees across platforms to choose the best for you.
The entire ICBC USD to OCBC remittance process can be summarized into three core stages: prepare information, app purchase foreign exchange, app remittance. Accuracy of information entry is the primary guarantee of success. Be sure to repeatedly verify recipient name, account number, and SWIFT Code to avoid delays due to spelling errors or account mismatches. Strictly following this tutorial ensures safe completion of remittance. Notably, recent Chinese personal information protection regulations do not affect normal cross-border transfers of personal funds. If you encounter any issues, call ICBC customer service hotline 95588 for assistance.
Immediately contact ICBC. If funds have not been remitted, the bank can stop the transaction. If already remitted, the bank will try to recover, but this may incur extra fees and success is not guaranteed. Therefore, carefully verify before submission.
Remittance failures usually have several common causes. Check for the following:
- Information Error: Recipient name, account number, or SWIFT Code incorrect.
- Purpose Mismatch: Remittance purpose inconsistent with purchase purpose.
- Quota Exceeded: Remittance amount exceeds remaining annual purchase quota.
ICBC typically has no strict upper limit on single remittance amounts. However, your total remittance is strictly limited by the Chinese resident annual convenience foreign exchange purchase quota (equivalent to $50,000 USD). Ensure your remittance is within the available quota.
