All our FIBCs are fully UN certified for dangerous goods shipping. We tailor each bag's safety setup to match your exact hazard rating, covering PG I, PG II and PG III packing groups, so the configuration always fits your material's actual risk level perfectly.
For sites handling flammable dust or exposed to volatile gas buildup, we supply industrial-grade anti-static FIBC options. Both Type C and Type D styles are available, with surface resistivity kept under 10^9 Ω. Type C bags come fitted with grounding plates to release static steadily during loading and unloading. This eliminates spark hazards in high-risk working environments, and we can provide official anti-static test reports for your filing and inspection needs.
Built to handle tough long-haul transit and repeated handling, these UN bags use heavy-duty fabric starting at 180g/m². We mix UV stabilizers into the raw material during production to resist outdoor aging and fabric degradation. Each bag is built with a 6:1 safety factor. All lifting loops and sewing threads use flame-retardant high-strength material, staying sturdy and tear-free even under harsh transport conditions, with zero structural failure under full load.
We provide full documentation with every shipment. You'll get official UN certification paperwork and complete type test data, including drop testing, stacking compression, positive pressure tightness and vibration test results. All parameters and test records are fully transparent, making compliance checks and customs clearance much simpler for you and your end clients.
These certified bulk bags work for most common dangerous goods shipping scenarios. They are the required packaging grade for hazardous chemicals like sodium hydroxide, calcium chloride, ammonium nitrate fertilizers and various persulfate products, all of which mandate valid UN certification for domestic transit and export.
They're also widely used for flammable solids and fine combustible dust, including aluminum powder, magnesium powder, sulfur powder and carbon black. Every finished bag goes through strict airtightness testing to stop fine dust leakage, removing major flammable risks during loading, unloading and shipping.
For eco-hazardous materials bound for the EU and other overseas markets, UN certification is basically mandatory. These materials face tight international packaging and customs rules, and our certified bags fully meet those cross-border compliance standards to avoid clearance delays.
Beyond standard chemicals, we also support packaging for mining concentrates and smelting slags that contain hazardous components, fully meeting industrial dangerous goods transport requirements.
Our UN certificates are issued by official entry-exit authorities and EU-recognized institutions, fully verifiable on official systems. We also hold valid ISO 9001:2015 certification, ensuring every production batch follows standardized quality control procedures.
Before dispatch, every batch undergoes strict sampling inspection following UN 6.1.5 standards. We provide original test reports for all core performance items and fully support third-party on-site witnessing and testing to meet your audit requirements.
Our factory spans 30,000 square meters, with a dedicated independent production line for dangerous goods packaging. We maintain a steady monthly output of 300,000 UN bags. Core certified fabrics and lifting accessories are always in stock, so we can guarantee stable lead times even for large-volume orders.
Customer FAQ
Q: Can I get your official UN certificate for verification?
A: Sure, we can share full certificate copies anytime for your review and customs preparation. UN packaging follows type certification rules, which means our bag model has passed all official UN performance tests. You can use this certified bag type for all materials that fall within its corresponding hazard classification range.
Q: How do you ensure bulk goods match the confirmed sample?
A: Every production batch has a unique batch number and complete production records. We strictly replicate the sample's raw material formula, weaving standards and stitching details in mass production, with zero tolerance for quality deviation. You're also welcome to arrange third-party random sampling and pre-shipment testing to confirm consistency.
Q: Are these bags suitable for highly corrosive materials?
A: Standard PP fabric cannot withstand strong acid or alkali corrosion. For highly corrosive cargo, we first assess your material's specific properties. We typically recommend customized protective liners like PE film or aluminum foil lining for enhanced corrosion resistance. For the best compatibility, we suggest sending a small material sample for a pre-production matching test.
