Hello...I ordered some good's from aliexpress..The seller provided me the tracking number as SYBABO0045983...I have never heard of such a tracking number or come across it..It says it's from pos malaysia and the order has been shipped..But there is no tracking information on any of the tracking sites...Can anyone help me know whether it's real or not??

SYBABO0045983 is a Sunyou parcel. You can track it here in a couple days: http://www.track-chinapost.com/sunyou-tracking.html

I ordered a package and was given this tracking number: LW003503333CN

I tracked it through the system and it had status updates, so
I'm assuming its real. But it has been stuck on Departure Export Customs, and the status is On Route. I just want to confirm if this is real and what to expect in terms of delivery. I've never dealt with China Post before.

Hello,
Could you tell me where is my package?

On my follow-up, this one does not move any more since 09/03/2017 and it is also repeated twice.
Is it blocked at customs in China or is it part of China?
Thank you

No it is neither chemical nor electronic.
It's just a hood scoop with it's fixing screw
