How long does it take to send something from Singapore to Chengdu, China by courier? The cost is how to calculate, thank you!

Want to hurry up with DHL express customs clearance time efficiency in all aspects are very good is the cost of expensive (customs clearance no problem conservative point said 3 days absolutely can be to)! Want to be cheaper to use special line (that is, specializing in Singapore to China's special line) clearance is good is the time limit will be to DHL slower (customs clearance is no problem to be conservative that the general 5 days can be to)! As for the cost of express delivery there is a volume of weight length times width times height divided by 5000 is the method of calculating the volume of weight, which big according to which calculation! The specific cost depends on how much you weigh!
