Cainiao “Return”: what it means

The short answer

Take action

Your package is going back, and Cainiao says the line may not use the word return. 'Unclaimed', 'Storage term expired' and 'Unsuccessful delivery' can all mean this. The seller or marketplace decides on a refund or a replacement.

When to act: If no refund or replacement has been offered 7 days after this line, file a complaint and we send it to Cainiao.

Also shown as: “Unclaimed” · “Storage term expired” · “Unsuccessful delivery” · “Item detained (unfit for Airmail delivery) and returned to sender” · “Security Check Failed” · “Package returning” · “Returned parcel is signed by seller” · “Package delivered to sender”

What to do now

Work out which route applies from the exact words in your tracking history.
Check the address and telephone number on your order before you order again.
If your order page still shows a delivery window, note it, because AliExpress's Buyer Protection is tied to it.
Look at your order page and your payment account for a refund.
Keep a screenshot of the line with its date, and your tracking and order numbers.
Still not sorted? File your complaint here. We write it with you and send it to Cainiao, so you do not have to chase it yourself.

What does “Return” mean?

Cainiao's FAQ gives three routes. If nobody collected it in the time the post office gave, tracking shows 'Unclaimed' or 'Storage term expired'. If an unclear address or telephone number stopped it reaching the local post office, tracking shows 'Unsuccessful delivery'. If it failed the security check, tracking shows 'Item detained (unfit for Airmail delivery) and returned to sender', and the status 'Security Check Failed' means it could not be shipped.

A package can also go back before it leaves China. In one history a customer shared, 'Airline handover problem at departure transport hub' was followed by 'Package returning' and, about a day later, 'Returned parcel is signed by seller', with no reason given. Customers also report 'Import clearance failure' at customs. Cainiao publishes no time for the trip back.

Why does Cainiao show it?

Not collected before the deadline
An unclear address or telephone number
A failed security check, such as an item not fit for air transport
A problem handing the package to the airline, in one shared history
Failed import customs clearance

How long does it last?

Expect 'Package returning' during the trip and 'Returned parcel is signed by seller' at the end. Cainiao gives no time for this. The seller or marketplace then decides on a refund or a new shipment.

Who is responsible for a late or missing package from Cainiao?

If you bought online from a business, the seller or marketplace is usually the one to sort it out. The seller chose Cainiao and is its customer, so a late or missing order is in most cases for the seller to put right, with a replacement or a refund. Cainiao's own FAQ also points to the seller when no tracking has appeared 12 days after shipment. On AliExpress, the platform's own rules decide refunds: its Buyer Protection covers an item that did not arrive or was lost in transit, within the guaranteed delivery window on your order page. For a UK order, the Consumer Rights Act, section 29, keeps goods from a business at the seller's risk until you have them, unless you hired a carrier the seller did not offer.

If you sent it yourself, Cainiao is unlikely to be your direct carrier, as it describes its cross-border services as primarily for merchants, brands and e-commerce platforms. If you booked through a shipping platform, your contract is likely to be with that platform, under the terms you accepted. We found no public Cainiao terms for private senders, and no standard cover amount.

Questions about “Return”

Why does my Cainiao tracking say Unclaimed?

Cainiao says this means nobody collected the package in the time the post office gave, so it is going back. 'Storage term expired' means the same.

Does Cainiao always show return when a package goes back?

No. Cainiao says a return can show as 'Unclaimed', 'Storage term expired', 'Unsuccessful delivery' or 'Item detained (unfit for Airmail delivery) and returned to sender'.

What does Security Check Failed mean on Cainiao?

Cainiao says the package failed the security check and cannot be shipped, and that such items show as detained and returned to sender.

Do I get my money back if a Cainiao package is returned?

That is for the seller or marketplace to decide, not Cainiao. On AliExpress, its own rules decide the refund.
