Transporting hazardous materials requires packaging that ensures the highest level of safety. This is where UN Certified FIBC Bags come in. These bulk bags are designed and tested in accordance with United Nations recommendations for the safe handling and shipping of dangerous goods.

In this guide, we outline the key safety features, certification process, compliance norms, and applications of UN Certified FIBCs.

1. What Are UN Certified FIBC Bags?

UN Certified FIBCs are heavy-duty jumbo bags specially designed for transporting hazardous or dangerous goods classified under the UN Orange Book. These bags undergo stringent testing and are labeled with a unique UN code confirming their compliance.

2. Key Testing Standards & Criteria

• Drop Test: Evaluates durability when dropped from height (usually 1.8m)
• Top Lift Test: Confirms the bag can safely lift its designated SWL
• Stacking Test: Measures the bag’s resistance to vertical load
• Tear Test: Tests resistance to propagation of a tear
• Topple Test: Checks stability during transit

3. Understanding the UN Marking Code

Every UN Certified FIBC features a unique marking like:

• 13H1: Woven PP bag without coating or liner
• 13H2: Woven PP bag with coating
• 13H3: Woven PP with liner
• 13H4: Woven PP with coating and liner

4. UN Marking and Printing Requirements

The UN marking must be printed on each certified bag and include critical compliance information. A typical marking appears as:

UN 13H3/Y/1000/25 IND/GOJIYA/235678 

Here’s what it means:

• 13H3: Bag type (Woven PP with liner)
• Y: Packaging group (Y = medium danger)
• 1000: Maximum gross mass in kg
• 25: Year of manufacture (e.g., 2025)
• IND: Country code of manufacturer
• GOJIYA: Manufacturer’s name
• 235678: Certification/test report number

5. When Do You Need UN Certified FIBC?

• Shipping hazardous chemicals, solvents, or pharmaceutical intermediates
• Exporting to countries that mandate UN packaging for dangerous goods
• Handling flammable powders, oxidizers, or environmentally harmful substances

6. Important Compliance Notes

• UN Certified FIBCs must be manufactured under a QA system (ISO recommended)
• Each batch must be tested and documented
• Only qualified suppliers should be used for regulated shipments
• Reusing UN FIBCs is not advised unless explicitly permitted by regulations

Export Tip: Always verify destination country regulations on hazardous cargo. Labeling, liner type, and documentation may vary by region.

Final Thoughts

UN Certified FIBC Bags are essential for the safe, legal, and reliable transport of hazardous goods. Whether you’re a chemical exporter or logistics handler, choosing the right UN FIBC protects both people and cargo.
