Ordinary parcel charges are low; EMS is divided into regions and types (such as certificates and articles), and it is charged according to the weight of articles, and there are domestic ones (item 10). In comparison, the cost of EMS is much higher.
2. Different time limits
EMS is a time-limited service, and there is a time-limited commitment to the mail sent (such as the next morning, the next day, the second day, the third day, etc.). ). If this period is exceeded, it will be liable for compensation; EMS is delivered by hand and delivered to the recipient in person, which is a little faster. Ordinary express delivery has no time limit commitment.
3. Different services
The service of EMS is similar to "three links and one access". Items that need express delivery will be delivered home. In principle, I am required to sign for them, while ordinary express delivery is not so strict. Small packages may be delivered to your door, while some big packages need me to pick them up at the post office.
