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.
