Is this one abnormal for Mexico? RS163733305CN
5 weeks yet still no update in local Mexico. There should be local tracking from my previous experience sending to Mexico from China.

1. It could be abnormal, this is what I found for you:
International Mail# RS163733305CN Tracking Result
Summary
Tracking number Origin Destination Status
RS163733305CN CHINA MEXICO On route

History Detail
Local date/time Activity Location Remarks
25-Jul-2016 16:33 Received by Post Office 51001020
26-Jul-2016 14:21 Departure export customs GUANGZHOU

2. So we know the parcel is On route to Mexico. May I suggest you read this for Mexico:
http://track-chinapost.com/China_Post_Arrival_Time_Stat.php

3. By what you are saying you seem to be the sender of the parcel, you could call China Post Hot Line: 11185 (they speak only Mandarin) just to make sure the parcel departed China.

4. It might be at Mexico Post the problem for this parcel, maybe the recipient could call Mexico Post to find out.

Hope this help.
