In the process of customizing glass bottles, the calculation of transportation costs involves multiple key factors, which together determine the final transportation cost.

The choice of transportation mode is the primary influencing factor. Land transportation is suitable for short-distance or medium-short distance transportation, with relatively low costs, but the transportation time is longer. Sea transportation is suitable for large-scale and long-distance transportation, with relatively low costs, but the transportation cycle is relatively long. Air freight is suitable for urgent or high-value goods. It has a fast transportation speed but is relatively expensive. Railway transportation lies between land and sea transportation, suitable for medium and long-distance transportation, and has a moderate cost. Customers need to select the appropriate mode of transportation based on their own needs and budget.

The transportation distance is also an important basis. The farther the distance, the higher the transportation cost. Transportation companies usually calculate the cost based on the straight-line distance from the "departure point to the destination" or the actual driving distance. For international transportation, cross-border additional charges such as customs duties and customs clearance fees also need to be taken into consideration.

The weight and volume of the goods are equally crucial. Transportation costs are generally calculated based on the weight or volume of the goods (taking the larger value), that is, "chargeable weight" or "volumetric weight". Weight-based billing is calculated based on the actual weight (in kilograms or tons), while volume-based billing is calculated by multiplying the volume (length × width × height, usually in cubic meters) by a volume factor (such as 1:5000). Since glass bottles are fragile items, their volume after packaging may be relatively large, and volume-based charging may become the main basis.

In addition, packaging requirements, destinations and transportation routes, as well as transportation time, will also have an impact on transportation costs. The cost of packaging materials, the complexity of packaging and the weight will be directly included in the expenses. Remote areas or regions with poor transportation may incur additional charges. The tariff policies and customs clearance procedures at the destination during international transportation will also increase costs. Express transportation costs more, while regular transportation costs less but takes longer.
