UN Certified FIBC Bulk Bags
Engineered for safety and reliability, our HAZMAT-certified bulk bags are approved for the transport of hazardous materials worldwide. Trusted by industries that demand the highest standards, these bags deliver proven protection in the most critical applications.

UN Certified FIBC – What Does This Mean?
A UN Certified bulk bag is specifically engineered and tested for the safe handling of hazardous materials. To earn certification, each bag must undergo a series of demanding UN performance tests and comply with detailed labeling and marking regulations.
Employees involved in selling UN rated products are also required to complete formal training in UN packaging standards to ensure full compliance and safe distribution.

Rigorous Testing And Applications For UN Bulk Bags
Before a UN-rated bulk bag can be certified, it must pass a series of demanding performance evaluations. These include top lift, stacking, drop, topple, righting and vibration tests—each designed to confirm the bag’s ability to safely contain and transport hazardous materials.
To qualify, bags are filled to at least 95 percent capacity with evenly distributed product, often the same material they will carry in service. Only when a bag endures this process without rupture or leakage is it approved to display official UN markings.
UN Certified bulk bags are built for demanding environments and approved to handle hazardous and sensitive materials across industries.
