Handling Guide of Loading 20*1000L IBC Tanks in 20ft Container
The liquid chemicals supplied by Foreverest Resources are sometimes packed in IBC tanks for shipping according to buyer requirements. Such as Gum Turpentine, a T.E.U (twenty feet equivalent unit) usually only loads 18*1000L IBC tanks (Figure 1). In recent years, COVID-19 has had a logistical impact on the global supply chain, resulting in continued high ocean freight rates. How to load and unload 20*1000 liter IBC tanks in a 20ft container becomes a pragmatic and worthwhile issue.

In general, a 20ft container is L6058mm*W2438mm*H2591mm. Its inner size is L5898mm*W2352mm*H2385mm. A regular 1000 liter (275gal) IBC tank is L1200mm*W1000mm*H1150mm (with pallet). In our case, we package the liquid chemicals by Schutz® MX1000 IBC ECOBULK. The MX1000 is L1200mm*W1000mm*H1160mm (with pallet), which is 10mm higher than a traditional IBC tank.
The height dimension of the door frame size of the 20ft container is W2286mm*H2261mm (Figure 2), which needs the forklift driver quite skillful when loading the last four IBC tanks and unloading the first four IBC tanks.

Loads 20*IBC tanks using the “Long side” and “Short sides” of the IBC
One IBC tank is L1200mm*W1000mm. When “Front-viewing” it, its cross-sectional width is 1000 mm, which is the “Short side”. When it is rotated 90 degrees and “Side-viewing” it, its cross-sectional width is 1200 mm, which is the “Long side” (Figure 3). Taking advantage of IBC size, it can load up to 20*IBC tanks. (Figure 4)

Loading the last four IBC tanks
Here are the details and tips for reference when working:
- First, a forklift lifts the upper IBC tank of the “short side”, and at the same time, the workers remove the lower IBC tank of the “short side” by manual hydraulic forklift.
- After conventional loading of the below IBC tank of the “Long side”, the last IBC is slowly loaded into the container at a certain inclination angle using the slope of the dockboards on the ground.
Unloading the first four IBC tanks
Here are the details and tips for reference when working:
- Unload in the order of “Long side – Above” -> “Long side – Below” -> “Short side – Above” -> “Short side – Below”.
- The forklift drives into the “long side” surplus space (Figure 4) and lifts the “Long side – Above” IBC.
- When forklift reversing, take care to use the inclination angle of the dockboards on the ground so that the IBC can go over the beam of the container door.
- While the workers use a human hydraulic forklift to lift the pallet of the “Short side” IBC tank, the forklift lifts the above IBC at the same time. At this point the workers move out the IBC below to the side. This allows the forklift to be easily reversed to unload the IBC.
