UN Certified Bulk Bag for Your Hazardous Material
Handling hazardous materials safely isn’t just about regulation—it’s about risk prevention, reputation, and responsibility. UN Certified Bulk Bags (also known as UN FIBCs) are the global standard for safely transporting dangerous goods. But with multiple types, classifications, and regulations, selecting the right UN bulk bag can be challenging.
This guide helps you understand how to choose the right UN Certified FIBC based on your material type, hazard class, packaging group, and transportation needs—ensuring compliance, safety, and efficiency.
What is a UN Certified Bulk Bag?
A UN Certified FIBC (Flexible Intermediate Bulk Container) is designed and tested under United Nations Recommendations on the Transport of Dangerous Goods. These bags must pass a series of rigorous tests such as:
- Drop test
- Top lift test
- Tear test
- Stacking test
- Righting test
Each certified bag is marked with a UN code, indicating:
- Type of bag
- Material hazard level
- Packaging group (I, II, or III)
- Country and manufacturer code
- Year of manufacture
Why It Matters: Hazards of Using Non-Certified Bags
Using non-certified or inappropriate bulk bags for hazardous materials can lead to:
- Regulatory penalties
- Environmental damage
- Worker injury
- Shipment rejection
- Loss of business credibility
Did You Know?
Over 50% of international hazmat shipping rejections are due to incorrect or uncertified packaging.
Step-by-Step Guide to Selecting the Right UN Bulk Bag
Step 1: Identify Your Material’s Hazard Classification
Check the UN Number and hazard class (1–9) of your material under the UN Model Regulations. Common examples include:
| Hazard Class | Description | Example Materials |
| Class 3 | Flammable liquids | Paints, Alcohols |
| Class 5.1 | Oxidizing substances | Hydrogen Peroxide |
| Class 6.1 | Toxic substances | Pesticides, Industrial Solvents |
| Class 9 | Miscellaneous dangerous goods | Lithium Batteries, Asbestos |
Step 2: Determine the Packaging Group
The Packaging Group (PG) indicates the level of danger:
- Group I (X Rated Bags): High Danger
- Group II (Y Rated Bags): Medium Danger
- Group III (Z Rated Bags): Low Danger
Choose a UN bag rated for your packaging group or higher. For example, a Y-rated bag can be used for PG II or PG III but not PG I.
Step 3: Choose the Correct UN Bag Type
| FIBC Type | Characteristics | Used For |
| 13H1 | Woven PP without coating or liner | Dry solids, non-hygroscopic |
| 13H2 | Woven PP with coating, no liner | Fine powders |
| 13H3 | Woven PP with liner, uncoated | Moisture-sensitive powders |
| 13H4 | Woven PP with liner and coating | Hazardous chemicals, toxic powders |
📝 Tip: For materials that are moisture-sensitive, choose 13H4 with inner polyethylene liner and outer coating.
Step 4: Validate Testing and Certification
Every UN FIBC must pass:
- Top Lift Test: With 6x safety factor
- Drop Test: 1.2–1.8 meters depending on PG
- Righting Test
- Stacking Test
- Tear Test
Ensure your supplier provides:
- UN Certificate
- Test Report
- Manufacturer’s Declaration
Step 5: Check Regional Compliance
Different countries may have additional regulations:
| Region | Regulatory Body | Notes |
| 🇮🇳 India | DGFT, PESO | Follows UN + local hazardous goods packaging rules |
| 🇺🇸 USA | DOT, CFR Title 49 | Mandatory UN Certification |
| 🇪🇺 EU | ADR | UN Compliance plus vehicle safety rules |
| 🇦🇺 Australia | ADG Code | Based on UN Recommendations |
📝 Tip: For geo-targeted shipments, mention compliance with specific regional codes in your product label and customs documents.
Bonus: Tips for Safe Handling and Transport
- Always inspect bags before use—no tears, UV damage, or broken loops.
- Don’t overload. Stay below max SWL (Safe Working Load).
- Use certified lifting mechanisms—never drag bags.
- Store bags in dry, shaded environments—UV rays degrade polypropylene.
- Rotate stock (FIFO) to avoid material degradation.
- Add labeling in local languages for regional compliance (GEO SEO boost).
Common Industries Using UN FIBCs
| Industry | Hazardous Material Handled | Recommended Bag Type |
| Chemicals & Pharma | Caustics, peroxides, solvents | 13H3 or 13H4 (X/Y) |
| Paints & Pigments | Titanium dioxide, alkyds | 13H2 or 13H3 (Y/Z) |
| Mining & Minerals | Lead ores, barium, fluorospar | 13H4 (X-rated) |
| Fertilizers & Agri | Ammonium nitrate, phosphorus | 13H2 or 13H3 |
💡 Pro Tip: Always ask for test certificates and traceability documentation with every bulk bag shipment.
