Leftover RMB in China: Exchange Receipts, Reconversion and Departure Planning

Do not leave a large envelope of unused renminbi until the airport departure queue. Converting travel cash back into foreign currency is possible, but the documents depend on the amount, where you exchange it and how you obtained the RMB. The most useful thing to keep is the receipt from your original foreign-currency exchange.

Last checked: 15 October 2026. This guide concerns leftover travel cash in mainland China, not overseas transfers, employment income or investment proceeds. Bank counters make the final document and currency-availability checks.

Choose the right route for your remaining cash

The first three rows summarize the State Administration of Foreign Exchange's reconversion rules. These are documentation thresholds, not a promise that a counter has your requested banknotes. They are expressed in US-dollar equivalents: they do not mean you must receive US dollars.

Keep the right receipt from the start

An exchange receipt is commonly called duihuan shuidan (兑换水单). Put it with your travel documents when you change foreign cash into RMB. A restaurant receipt, an ATM withdrawal record and a shopping tax-refund form serve different purposes. Keep a readable backup for reference, but retain the original rather than assuming a photograph will replace it at the counter.

Before making another withdrawal near the end of your trip, count what you already have and subtract planned cash spending. Our foreign-card ATM guide covers obtaining cash; reconverting it is a separate transaction. Withdrawing more money merely to avoid using up small notes can create an unnecessary second exchange.

What Bank of China's current instructions say

Bank of China's January 2026 foreign-currency purchase instructions say foreign customers use branch counters. For unused RMB originally converted from currency brought into China, its published requirements are valid identification up to USD 500 equivalent per day, and identification plus the original exchange receipt above that amount, with the original conversion within 24 months.

Do not apply the familiar “USD 50,000 annual quota” to an ordinary visiting tourist: the bank describes that convenience quota for domestic individuals and foreign permanent-residence-card holders, not all foreign visitors. Its page also separates conversion of lawful RMB income, which requires supporting documentation. If your cash has a different origin, explain it instead of trying to fit the transaction into the wrong category.

Ask these questions before travelling to a branch

• Does this branch handle foreign visitors' unused-RMB reconversion?
• Can it provide cash in my requested currency, and does that need arranging in advance?
• Which original documents are needed for my amount and source of funds?
• What is the applicable cash exchange rate, any separate fee, and the final amount I will receive?
• Which counter hours apply on my intended day?

Useful wording is: “我想把没用完的人民币兑回外币。需要什么材料？” — “I would like to convert unused RMB back into foreign currency. What documents do I need?” Add the currency and approximate RMB amount. A clear question is more useful than asking only whether the branch “does foreign exchange.”

We do not quote a fixed rate or fee: the relevant comparison is the final foreign-currency amount offered for your RMB at that counter. Bank of China's foreign-exchange service page warns that exchange rates change and that some currencies are available only at selected outlets. A rate from your phone is not necessarily the counter's cash quote.

A workable final-two-days plan

1. Two days before departure: separate money needed for transport, meals and any agreed cash expenses from genuine surplus. Find the original exchange receipt.
2. Before visiting a counter: confirm the service and currency stock. Leave room to use a different branch or day if the first cannot help.
3. At the counter: explain your funds' origin, confirm the total received before agreeing, then check the currency and amount handed over.
4. Afterward: keep the new receipt with the original and retain enough RMB for expenses you still intend to pay in cash.

Do not count a pending hotel deposit release as cash already available to exchange. If that affects your budget, read our hotel deposit and card-preauthorization guide before checkout.

When the airport is the wrong fallback

The USD 1,000 provision is tied to a qualifying departure location, not the word “airport.” Ask which side of the departure process the counter is on and whether you can reach it on your itinerary. Do not cross a checkpoint early solely on the assumption that exchange will be available beyond it. No specific airport counter, opening schedule or currency stock is guaranteed here.

For a small remainder, compare the time and exchange cost with using it for purchases you already intended to make. For a substantial remainder without the original receipt, contact the bank before departure and disclose the circumstances. Do not split a transaction or use another traveller's documents to evade checks.

Finally, reconversion is not a shopping tax refund. If your question concerns eligible goods rather than leftover cash, use our departure tax-refund guide. The forms, eligibility and departure steps are different.
