Double-walled IBC for hazardous goods: VARIBOX FC and CC
A double-walled IBC consists of an inner container and a fully closed outer container. If the inner container leaks, the outer container holds the liquid: 110 % spill containment is built in. So you do not need a separate spill tray.
VARIBOX makes double-walled IBCs in three sizes: the VARIBOX FC 1000, the FC 800 and the compact CC 250. All three are UN/ADR approved, have DIBt approval and are built for reuse in chemical distribution.
What is a double-walled IBC?
A double-walled IBC, also called a double-walled container or tank, has two walls: the inner container (primary containment) and the closed outer container (secondary containment). Hence the name VARIBOX FC: Full Containment.
The VARIBOX FC consists of four parts: the pallet made of recycled material, the outer container with built-in spill containment, the inner container for your product and the rotomoulded cover that closes it all.
Unlike a standard composite IBC, the VARIBOX has no valve at the bottom. It is emptied via an extractor tube fitted through the cover into the inner container. The system stays closed while pumping.
VARIBOX CC 250: the most compact double-walled IBC
The VARIBOX CC 250 is only 60 cm wide. You move it with a pallet truck, without lifting drums onto a spill tray.

Advantages of a double-walled IBC
- No spill tray needed: 110 % spill containment is built in and approved by DIBt. You can place the IBC wherever you want.
- Closed system: no valve at the bottom, no opening during emptying and no direct contact with the product. The Safeline and NS4 couplers close automatically when disconnected.
- Little residue: after emptying, less than 0.5 litre in total remains in the container and extractor tube.
- Reusable: all three models last up to 10 years; only the inner container is replaced after 5 years.
- In your colour: including blue, dark blue, yellow, orange, green or natural.
Which products is it for?
For hazardous substances that you transport and store on site: corrosive acids, alkalis and oxidising agents. Examples: peracetic acid, sodium hydroxide and phosphoric acid. Looking for a 1000 litre IBC? See 1000 litre IBC. More about the IBC with integrated spill containment.

Frequently asked questions about double-walled IBCs
What is the difference between a single-walled and a double-walled IBC?
A single-walled IBC such as the VARIBOX SC has one container and is emptied via a 2″ ball valve (DN50). A double-walled IBC such as the VARIBOX FC or CC also has a closed outer container with 110 % spill containment and is emptied from the top, via an extractor tube.
Do I need a spill tray?
No. The 110 % spill containment is built in and approved by DIBt (abZ Z-40.21-534), for the FC 1000, the FC 800 and the CC 250.
Is the double-walled VARIBOX UN approved?
Yes. All three models carry the UN 31HH1/Y marking and are approved for packing groups II and III, for road (ADR), rail (RID) and sea (IMDG). The full marking per model is in the table above.
How long can I use a double-walled VARIBOX?
Up to 10 years, for the FC 1000, the FC 800 and the CC 250. Only the inner container is replaced after 5 years.
Which seal should I choose: EPDM or Viton?
That depends on your chemical. More in the FAQ EPDM or Viton.
