United Nation has established directives for the safety of human and property and to prevent environment pollution. They have outlined specific criteria and standards for FIBC when it requires to store and transport dangerous goods.

BulkBags Australia can supply FIBC bulk bags for hazardous materials that comply UN standards by testing through independent reputed testing laboratory, usually LABORDATA in Germany.

UN certified bags have labelling and visual pictogram requirement for identification. Labelling depends on hazardous materials that will be filled in that specific bag. In Australia, appropriate labelling on FIBC bulk bags is required by the government and non-government authorities for transporting, storing and exporting of hazardous materials.

FIBC Bulk Bags Unique UN Number

UN bags have 3 levels of packing groups for dangerous goods transportation.

Degree of Danger - High, Medium, Low.
Degree of Danger Packing Group UN Symbol Max. Allowed Volume
High I X 1.5 m3
Medium II Y 3.0 m3
Low III Z 3.0 m3

For high degree of danger (packing group I), UN Symbol X is not applicable to FIBC, but only to rigid IBCs.

There are four types of FIBC for dangerous goods made from woven polypropylene:
13H1: woven PP without coating and without liner
13H2: woven PP, coated and without liner
13H3: woven PP, uncoated and with liner
13H4: woven PP, coated and with liner

A UN FIBC is certified by carried out the following tests successfully:

Top lift test: The FIBC is loaded with six times of the rated load.

Drop test: The FIBC filled with the rated load is dropped in an upright position from a height of 80 cm or 120 cm.

Topple test: The FIBC filled with the rated load is toppled from a height of 80 cm or 120 cm.

Righting test: After being toppled, the FIBC filled with the maximum load is lifted to an upright position on one or two loops.

Tear test: A 100 mm tear is made on one of the sides of the FIBC filled with the maximum load. The FIBC is then filled with twice its maximum load for a minimum of five minutes. Finally, the FIBC is suspended with its SWL for five minutes.

Stacking test: The filled FIBC with 1.8 times of rated weight is stacked on top of another FIBC.
