China Post international parcels actually go through a network called Global Postal Union. The members of this union are postal companies or post ministries of different countries and most of the countries in the world belong to this union.
So parcels from China will go through many of the union member countries before arriving destination. The destination country post company is responsible for the delivery.
The key point is: Once the parcel was given to customs or airline and it is on the way to the next union member’s system, China Post will no longer control the parcel and not even know the exact status and location of the parcel until the next union member country scan this parcel.
After China Post lost control of the parcel, in tracking result, the parcel status will seem to be freeze or stuck in such status as “sent to airline”, “Export Security Scan”, “Export Customs Scan” etc for a quite long time (2 to 4 weeks in regular season, and 4 to 8 weeks in rush season). Once the next postal union member scanned the parcel again and sends the data back to China Post through the Global Postal Union computer system, China Post then updates the parcel status with new information. If the destination country does not scan the parcel or does not send the scan result to GPU, the status will freeze forever. So if your parcel status freezes in STA, ESS, ECS status for a couple of weeks, it does not necessarily mean your parcel has any problem.
Although we can not predict the exact arrival time, it does not mean that we can know anything about the arrival time. Actually, we can use previous shipping statistic data and user feedback to estimate the approx arrival time.
Check our arrival time statistic report, you can easily find the average arrival time, max arrival time and shortest arrival time of parcels to your country.
In a rush season, arrival time might be double or triple of the regular season.
There are also many factors to affect the arrival time including national events and festivals, departure port traffic situation, etc. Actually not only China Post, Hong Kong Post, Singapore Post and any other countries’ postal service, but all also have the same problem.
