EMS is cheap! However, the time limit is unstable and the website is slow to update, but the customs clearance ability is very good, and there is no refund for returned parts. Among the four companies, DHL is the best and most stable one, but the price is very expensive, UPS and Fedex are in the middle, Fedex is not very stable, and there are many transit countries. It is better for Southeast Asia to take these two routes, while TNT Europe is good and its timeliness is very stable.
