The billing start points are different, and they often occur at the same time. For specific rules, refer to the shipping company's charging terms.
Q: How long is the free time period generally?
A: It depends on the shipping company and route. For exports, it is commonly 3–7 days; for imports, commonly 5–10 days. It may also vary by port and container type. For the exact days and rates, refer to the terms confirmed at the time of booking.
