International transportation services are usually divided into two ways: sea freight and air freight. Sea freight refers to the way goods are transported internationally using sea vessels. Sea freight is generally suitable for bulk cargo transportation, especially for heavy and bulky goods, sea freight can provide relatively low transportation costs. The disadvantage of sea freight is the longer transit time, which usually takes weeks or even months to complete. Air freight refers to the way goods are transported internationally by aircraft. Air freight is usually suitable for urgent, time-sensitive or short-term cargo transportation requirements. Although the cost of air freight is higher than that of sea freight, it can provide fast transportation speed and reliable cargo tracking service. Whether by sea or air, international transportation service providers usually provide services including cargo shipment, customs clearance, cargo insurance and tracking. Choose a shipping method that suits your needs, which can be determined based on factors such as the nature of the goods, shipping time requirements, and budget.
