UN Certified FIBC Bulk Bags for Hazardous Materials

What is a UN Certified FIBC?

A UN Certified FIBC is a bulk bag designed and approved to transport and store hazardous materials under DOT and international shipping regulations. In order to qualify as a UN Certified bulk bag, the FIBC must pass rigorous UN testing standards. In addition, each UN rated bulk bag must adhere to strict labeling and marking requirements.

Employees who sell UN rated products must complete a UN packaging standards certification program.

UN Certified FIBCs are commonly used in industries handling hazardous chemicals, catalysts, flammable materials, and regulated waste streams. These applications require packaging that meets strict regulatory standards for safe transportation and storage.

Selecting a UN rated bulk bag ensures the packaging complies with required testing and marking protocols when transporting hazardous materials under applicable transportation regulations.

What Tests Must a UN Certified Bulk Bag Pass?

In order to receive certification as a UN rated package, the FIBC must undergo a series of performance tests. Bags must pass ALL of the following tests:

Top Lift – Bag is filled to maximum gross mass and lifted by its loops to verify the lifting mechanism holds under load.
Stacking – Filled bags are stacked to simulate warehouse and container storage conditions.
Drop – A filled bag is dropped from a specified height to simulate handling impacts during loading and unloading.
Topple – Bag is tipped onto its side to test seam strength and resistance to lateral impact.
Righting – A filled bag is laid on its side and returned upright to test fabric recovery without tearing.
Tear – A controlled cut is made to measure resistance to tear propagation under load.

Southern Packaging engages the services of TEN-E Packaging Services, Inc. to test our UN rated products.

What Hazardous Materials Can Be Shipped in UN Certified FIBCs?

UN certified FIBCs are approved to transport a wide range of regulated hazardous materials across multiple DOT hazard classes, including:

Catalyst
ANFO
Explosives
Guar
Asbestos
Toxic Waste
Corrosives
Flammable Solids
Radioactive Waste

Are UN Certified FIBCs Required by Law?

Yes - the U.S. Department of Transportation (DOT) requires UN specification packaging for most hazardous material shipments under 49 CFR Parts 171–180. Manufacturers select UN Certified FIBCs when regulatory compliance is required for the safe transportation of hazardous materials. In many cases, the use of UN rated packaging is mandated by the Department of Transportation (DoT) and other governing authorities.

Using a properly tested and labeled UN bulk bag helps ensure compliance with transportation regulations while maintaining safety throughout the supply chain.

How Do You Choose the Right UN Certified FIBC?

Selecting the right UN certified FIBC depends on three factors: your material’s hazard class and packing group, any static-discharge requirements, and your fill/discharge process.

Hazard class and packing group – Identify your material’s DOT hazard class and packing group (I, II, or III). Choose packaging with the corresponding X, Y, or Z rating.
Static sensitivity – For flammable or combustible materials, select a Type C (conductive) or Type D (anti-static) FIBC to prevent ignition from static discharge. [Link to /fibcs/type-c-bulk-bags and /fibcs/type-d-bulk-bags]
Moisture exposure – For moisture-sensitive materials, choose a coated bag (13H2 or 13H4) or one with a factory-installed PE or PP liner (13H3 or 13H4).
Fill and discharge method – Match the bag’s top fill and bottom discharge configuration to your equipment and process workflow.

Frequently Asked Questions

What exactly is a UN Certified FIBC bulk bag?

A UN Certified FIBC is a bulk bag specifically engineered and tested to safely transport and store hazardous materials. These bags must pass rigorous UN performance tests and meet strict labeling requirements to qualify for certification. Southern Packaging's UN bulk bags are manufactured in ISO and BRCGS certified facilities to ensure the highest safety standards.

What testing is required for UN Certified bulk bags?

Our UN FIBCs undergo comprehensive testing including top lift, stacking, drop, topple, righting, and tear tests conducted by TEN-E Packaging Services. These tests simulate real-world conditions to verify the bags can safely handle hazardous materials during transport and storage.

What types of UN Certified FIBCs do you offer?

We provide a complete range of UN Certified bulk bags including all fabric types (A, B, C, and D) with options for coated/uncoated PP fabric, factory-installed liners (PE or PP), and high heat resistant materials. Our bags feature multiple filling/discharge options and carry safe working loads from 500-3300lbs with a 6:1 safety factor.

What hazardous materials are your UN bulk bags designed to handle?

Our UN Certified FIBCs safely transport diverse hazardous materials including explosives (ANFO), toxic waste, corrosives, flammable solids, radioactive waste, asbestos, and industrial materials like catalyst and guar. Each bag is specifically tested and certified for its intended hazardous material classification.

Are UN Certified FIBCs required by law?

In many hazardous material applications, the Department of Transportation (DoT) requires the use of UN rated packaging for transport. UN Certified FIBCs are designed to meet these regulatory requirements when transporting classified hazardous materials.

Who conducts UN bulk bag testing?

Southern Packaging engages TEN-E Packaging Services, Inc. to conduct required UN performance testing. Each bag must successfully pass top lift, stacking, drop, topple, righting, and tear tests to qualify for certification.

How can I verify a UN bulk bag is certified?

UN Certified FIBCs must carry proper UN markings and labeling in accordance with testing and regulatory standards. These markings confirm the bag has passed required performance testing.

What is the difference between standard FIBCs and UN Certified FIBCs?

Standard FIBCs are designed for non-hazardous dry flowable materials. UN Certified FIBCs undergo additional performance testing and must meet strict labeling and marking requirements to transport regulated hazardous materials.

What industries typically require UN Certified bulk bags?

Industries handling hazardous chemicals, catalysts, flammable products, explosives, toxic waste, corrosives, and regulated waste streams commonly require UN Certified FIBCs to comply with transportation regulations.

What is the difference between Type C and Type D UN certified bulk bags?

Type C (conductive) bulk bags have interwoven conductive threads and must be grounded during filling and discharge to dissipate static safely. Type D (anti-static) bags use engineered fabrics that dissipate static without a ground connection. Type C bags are used when a reliable grounding system is available; Type D bags are preferred where grounding is impractical. Both are available in UN certified configurations for flammable and combustible materials.

Can UN certified FIBCs be reused for hazardous materials?

UN certified FIBCs are generally designed for single-trip use when transporting hazardous materials. The UN certification applies to the bag as manufactured and tested - reuse may compromise structural integrity and void the certification. For regulated hazardous shipments, a new UN certified bag should be used for each shipment to maintain compliance.

What does the 6:1 safety factor mean in UN certified bulk bags?

The 6:1 safety factor means the bag’s fabric and construction are engineered to hold six times the rated safe working load (SWL) before failure. For example, a bag rated at 2,000 lbs SWL is built to withstand 12,000 lbs of force in testing. This margin accounts for dynamic stresses during lifting, transport, and handling.
