A UN-certified FIBC is not a normal bulk bag with a sticker. It is a specific design type that has passed the UN test sequence — top-lift, drop, tear, stacking and, where relevant, leakproofness — for a defined Packing Group. We keep the test reports and certificates ready so your dangerous-goods shipment is defensible at the border.

Any solid dangerous good in Packing Groups I–III that is permitted in flexible bulk packaging.

Pigments, resins and solids classified as dangerous goods.

Controlled, tested packaging for hazardous solids.

Bags ready for IMDG / ADR / RID shipment.
UN designs use the same fill/discharge and loop logic as standard bags, but every dimension and seam is fixed by the certified design.

Note: a UN design is certified as a specific design type with a defined Packing Group rating. The certificate and test report cover that design; we do not generalise one certificate across different designs or ratings.
