Excuse me, what's the difference between detention and demurrage without piling?

The difference is the rent-free status.

Rent-free period of container at the dock after arrival of goods (rent-free period of container): demurrage fee is free; ;

Rent-free period (rent-free period of container) when the container is towed away from the dock after the goods arrive in Hong Kong: detention-free; ;

Non-stacking period of container stacking at the wharf: free storage.

Generally, you apply for free time, that is, free demurrage+free detention.

(Introduction of relevant information about rent-free period/container-free period of wharf goods):

No-container period (rent-free period) refers to the use time of your box, that is, the time from the time you pick up the goods in the yard to the time you return them to the cabinet. Free use of boxes is dealing with shipping companies.

After heavy containers arrive at the destination port, they can generally be stored at the dock for a few days free of charge, and boxes can also be used for a few days free of charge. Free storage period and free container period are different in different countries and ports, usually 7 days. You can also apply for extending the container-free period at the port of departure according to the specific shipping company \ route. After the time is exceeded, demurrage will be charged.

If the container-free period is up, the shipowner can talk to the freight forwarder and ask him to write an application to the shipping company to try to extend the container-free period by about three or four days. If the company has a large cargo volume and has a contract with the shipping company, it can apply for a container-free period of14 to 20 days.

Difference:

Box-free period and stack-free period are two different concepts. Stack-free period refers to the time when your containers are stacked in the port area. After the stack-free period, there will be a fee every day, which is charged according to the regulations of the shipping company, that is, container demurrage fee.

In other words, the shipping company will charge you demurrage if you use the box for more than the free time. If the stacking time is exceeded, the overdue fee shall be paid. The overdue fee refers to the overdue stacking (occupation of the dock) fee caused by the container that has been piled (used) for free and not taken away (emptied) for more than the time specified by the dock. This fee and demurrage fee are completely two concepts.
