We just get information from shipping line ,they informed that if cargos arrived at destination ,if need changes ,they only send CCA to destination ,then using the code which I sent to you ,then can make customs clearance normally ,the attached original AWB can not be changed.
Could you confirm with your shipping how to do it ?or can you contact with your shipping company directly to explain it ?
If you have any problem ,please let me know ,we will contact shipping line .
