Your parcel is paused before international departure.
Export customs is the outbound checkpoint. The carrier or postal operator presents the shipment for customs/security control before it leaves the origin country.
If AliExpress/Cainiao shows Export customs clearance complete, customs has normally finished that stage. If the underlying carrier says held / retained for inspection, the parcel is still paused.
Check the exact carrier note, not only the progress barWhere the hold sits in the shipping journey.
Cainiao’s normal tracking flow places export clearance after the departure hub and before the shipment leaves the origin country.
Origin → export customs → flight → destination
The highlighted step is your current bottleneck.
How long has it been stuck?
There is no universal customs timer. Use the age of the hold as a practical trigger for what to check next—not as a guaranteed delivery estimate.
Select the hold time
Choose how long the exact “held / retained” status has shown with no newer carrier scan.
Monitor the next scan.
A short pause can happen during export processing. Check the full carrier history before assuming the parcel is stuck.
- Compare AliExpress tracking with Cainiao or the underlying carrier.
- Save a screenshot of the current status and date.
- Do not confuse “held” with “clearance complete.”
Read the next status correctly.
These labels look similar, but they point to very different outcomes.
Use this order of actions.
The goal is to collect enough evidence to know whether you simply wait or need the seller to intervene.
Open the full Cainiao history
AliExpress can simplify the timeline. Check the underlying carrier note and the exact wording/date of the customs scan.
Open official Cainiao tracking ↗Look for a retention reason
If the carrier mentions missing/inappropriate invoice data, declaration problems, or another explicit reason, send the screenshot to the seller.
Escalate when the hold persists
Ask the seller/shipper to check with their logistics provider. Keep screenshots, tracking history, and messages in case you later need an AliExpress non-delivery claim.
Two paths matter most.
Path A — Customs releases it
The next scan may say released, clearance complete, awaiting flight, or leaving the departure country. That means the export hold is over.
Path B — The parcel is returned
If tracking explicitly shows return to sender / export office return, the shipment is no longer following the normal outbound route.
Questions people keep asking.
Does “held by export customs” mean customs seized my AliExpress package?
No. A hold means the shipment is paused for review. Seizure/confiscation is a different outcome and should be indicated by a more specific carrier/customs update.
Can I contact Chinese export customs myself?
For an AliExpress parcel, the practical first contact is usually the seller/shipper or their logistics provider, because they control the shipment paperwork and carrier relationship.
Why can “export customs clearance complete” still sit for days?
Customs completion only finishes that checkpoint. The parcel can still wait for handoff, line-haul space, a flight, or the next physical scan.
What if AliExpress shows one status and another tracker shows something else?
Check the timestamp and carrier note from Cainiao or the underlying carrier. Different tracking interfaces can simplify, translate, or display events differently.
