1, Eurasian special line code S and code M are two different packaging specifications, and the difference between them mainly lies in the size and weight restrictions and the corresponding freight price. First of all, the capping size of S code is length+width+height ≤90cm, while the capping size of M code is length+width+height ≤ 120cm. Secondly, the weight of code S is limited to each piece 15 kg, while the maximum weight of code M is 30 kg. Finally, because the size and weight of code S are smaller than that of code M, the freight price of code S may be lower. However, the choice of S code or M code needs to consider the specific size and weight of the package, as well as the transportation budget and time requirements. It should be noted that the transportation standard of the Eurasian special line varies with the route, route, season and other factors, so it is best to consult the local logistics company or express agent first to understand the transportation standard and freight price, and then choose the S code or the M code.

Generally speaking, the choice of S code or M code depends on the specific needs and transportation requirements. If the package is small in size and light in weight, it may be more suitable to choose S code, because its freight price is lower. If the package is large or heavy, you may need to choose M code. Before choosing, it is recommended to consult the local logistics company or express agent to understand the transportation standard and freight price to avoid unnecessary expenses and delays.
