Generally we trade 20" Standard(20GP), 40" Standard(40GP), 40" High-cube(40HQ or 40HC) as general container. 

Other container as special container. 

It would be easy to book general container. and you need to book special container at least 10days before the vessel depart. 

1. Inner size.

Pls kindly check the image to get the inner size of the container. 

2. Capacity. 

Generally when we calculate the capacity, we need to know there is inevitable space waste when we load the container. 

So if your cargo are regular boxes and cartons, you can estimate as follows. 

20GP: 28-30CBM;

40GP: 58-60CBM; 

40HQ: 68-70CBM;

45HQ: 78-80CBM.

If your cargo are of different size and irregular, you can estimate as follows.

20GP: 25CBM

40GP: 55CBM

40HQ: 65CBM.

Or you can contact our customer service to make a 3D model to calculate whether the container can load your cargo.
