You mailed a return to a seller in China. It landed. Then it sat there. The tracking says “presented to import customs” and does not change for six weeks.
That is not bad luck. A return to China is treated as a brand-new import. Chinese customs works with the receiver, not with you, and one missing field can stop the whole thing: the receiver’s mobile number.
A return is an import, not a refund
When the package arrives in China, customs does not know or care that you already paid for it once. It sees goods entering the country. Someone has to declare them, prove what they are worth, and pay duty if duty is owed. That someone is the receiver.
This is why a return can sit for weeks while the seller tells you “we never got it.” The package is not lost. It is waiting for a person in China to clear it.
The phone number is the whole game
China Post sends the customs clearance code by text message to the receiver’s mobile number on the label. No number, no text. No text, no online clearance. The package goes into a holding queue and eventually back to you.
We saw this exact loop in the forum. A sender in Germany mailed a 10 kg return to Shenzhen. DHL’s online form did not require a phone number, so it was left blank. The package sat at customs for six days. The receiver called and was told it had already been sent back. The sender paid about 65 euros for shipping and got nothing but a return trip.
What the receiver has to do
- Call 11183 (EMS) or 11185 (China Post) with the tracking number. Ask specifically about “customs clearance for an imported parcel.”
- Or go in person to the local China Post office with ID and the tracking number. In most branches, the receiver clears customs and picks up the package at the same counter.
- Pay the duty if one is assessed. Many branches accept WeChat Pay. The sender usually cannot pay from abroad.
- Do it inside the notice window. Depending on the branch, that is roughly 7 to 15 days before the parcel is returned.
What you can and cannot do from abroad
You can: send the commercial invoice, the customs declaration, and photos of the label. Push the receiver to call the same day. Ask China Post for a written status update if you need it for a PayPal or bank dispute.
You cannot: clear the package for the receiver, pay the duty from your side, or change the delivery address once it is in China. The receiver has to act.
Why the trip back takes two to three months
Returned mail usually travels by the cheapest route available, often by sea. Add sorting, export scanning, and another customs pass, and 4 to 10 weeks is normal. A package that took 10 days to reach China can take 10 weeks to come home.
| Stage | Normal time |
|---|---|
| Your country to China | 3–10 days by air |
| Customs notice to receiver | 1–3 days after arrival |
| Receiver clears and pays | 1–3 days |
| No phone number on label | 2–6 weeks, then return |
| Return trip to you | 4–10 weeks |
Before you ship a return: a five-minute checklist
- Write the receiver’s mobile number in international format (+86…) on the label and on the customs form.
- Include a commercial invoice with the item name, quantity, and value. Mark it “returned goods.”
- Do not mark a return as a gift. A gift declaration invites a duty question you cannot answer.
- Photograph the label, the declaration, and the sealed box before you hand it over.
- Tell the receiver to expect a text from an unknown number and a call from China Post. Many people ignore both.
If it is already stuck
Get the receiver on the phone with 11183 or 11185 today, not next week. If customs asks for an invoice, email a PDF and a photo of the declaration. If the receiver refuses to clear it, ask China Post for the return in writing, and ask the seller to confirm the refusal in the chat.
That written trail matters. PayPal and card issuers rarely accept “it is stuck at customs” as proof. They want a dated status, a refusal, or a return scan. For the full timeline, see our guide to packages stuck in customs for weeks.
Quick answers
Can I pay the duty myself? Usually no. The clearance is tied to the receiver’s identity and phone number. A few branches allow a third party to pay in person, but you cannot do it from another country.
Can I change the address in China? Not from abroad. The receiver can ask at the pickup counter, and even then only before the parcel is loaded for delivery.
What happens if nobody clears it? It is returned to the sender after the holding period. Storage fees and return postage may apply, and those usually come out of your pocket.
If the seller has stopped answering, do not wait for the return to land. Start the refund clock now and keep the return tracking as evidence.
