Hi, I'm waiting for a shipment with tracking RJ695520901CN.
It has had some strange movements, here's the tracking situation:

2016-03-10 18:57:05.0 Yiwu city international eCommerce dept. received
2016-03-11 02:08:57.0 Yiwu city international eCommerce dept. customs scan
2016-03-11 06:25:33.0 leaving Yiwu city international eCommerce dept. ，next station Yiwu
2016-03-11 09:26:51.0 Yiwu Transit Station export security scan
2016-03-11 14:09:41.0 Yiwu Transit Station export customs cleared
2016-03-12 03:53:00.0 arrive Hangzhou Airport
2016-03-12 03:54:04.0 leaving Hangzhou Airport going to next airport/seaport
2016-03-15 17:56:17.0 Yiwu Transit Station export security scan

Why has it been twice in Yiwu transit station?

Thank you to everyone that could help.

I might be wrong but I suspect your parcel was suppose to leave around the 2016-03-12. But they were no room on the aircraft. so it came back and is trying again (2016-03-15) to catch an aircraft to your country Italy.

Hope this help.

Hi,
finally I contacted the seller, and he said that the package has been lost and he refunded me. But what happens to lost packages? Is it possible that it could be on track again?

Also, I have another shipment, tracking number is ZLT16042100048, but I can't track it on any site.
Who is the carrier? Is it a trackable number?
Thank you!

Possibly going back to seller or destroyed. Impossible to be on track again.

For tracking number ZLT16042100048, did you by thing on this site:
http://shop.borderfree.com/

If so you can possibly track it on their site, otherwise this is not a China Post number.

Hope this help.

Hi,
thank you very much! Actually I bought the item on aliexpress, I hope everything will be fine...
Thank you again!

1. May I suggest to contact seller and ask him what is the name of the transport company for your parcel and how can you track it.
2. From his answer you will be able to see what is going on with your parcel. Was it ship or not or were you scam by this seller?.

Hope this help.

1. May I suggest you read this for Singapore:
China Post Airmail Parcel Estimate Arrival Time
On this site:
http://track-chinapost.com/China_Post_Arrival_Time_Stat.php

2. Also, you might want to look at this extract for your parcel and this apply to any parcel in the world:

Customs & security delays:
Customs operates on their own schedule, and they don’t care how badly you want your package. Some places open and inspect almost everything, some don’t; some places process packages very efficiently, some do not.

With both Customs and security, if one item is suspicious, it may delay everything in the same dispatch.

You can find the full document on this site:

I can fly to China in 24 hours! Why does a package take weeks?

3. Please be aware that if there is no other scan on your parcel nobody knows were it is.

4. Are you sure that Singapore will track you parcel on their site. Have you call Singapore Post en ask them? If they did answer to a Yes they will track your parcel, then you have the answer that the parcel is not in the hands of Singapore Post.

5. Also please note that it's not all Post Office in the world that will scan a parcel before it goes to the Customs Office some do and some don't.

Hope the above information will be helpful to you.
