My friend sent a bottle of sea blue mystery water and a Lei Bei Ni air cushion to China by American Express. Why can't he send it back?

The reason why express delivery cannot be sent back in the United States may be that customs clearance takes time. Because express delivery takes the longest time in the customs clearance process, generally speaking, after the express delivery is completed, the subsequent delivery will be faster, but if it is detained by the customs, it is necessary to pay a spot check fine and may be postponed.

A very important feature of international express delivery is the difference of express delivery environment in different countries, especially the difference of express delivery soft environment. The application of laws to different logistics in different countries makes the complexity of international express delivery much higher than that of domestic logistics in a country, even blocking it.

Different countries and different levels of economic and technological development will cause international express delivery to be supported by different scientific and technological conditions, and even some areas cannot apply certain technologies at all, forcing the overall level of international express delivery to decline; Different standards in different countries also make it difficult to "connect" internationally, thus making it difficult to establish an international express delivery system; The customs and humanities of various countries have also greatly restricted international express delivery.

International express delivery refers to the express delivery and logistics business between two or more countries (or regions). The business of transferring letters, commercial documents and articles between countries (or regions) refers to the delivery method of releasing express mail through border ports and customs inspection between countries. After the international express mail arrives at the destination country, it needs to be transshipped again in the destination country before it can reach the final destination.
