In addition to the distance between the two places (related to the unit price of shipping), the sea freight also needs to be based on the actual situation of the goods, such as the weight and volume of the goods, whether they are special goods, whether they are all LCL or full containers.
These are just some basic freight charges. Usually, there are other additional fees for shipping, such as: 1, port miscellaneous fees, 2, dock fees, 3, security inspection fees, 4, seal fees, 5, document fees, 6, customs declaration fees.
