Specialty
UN Certified
Hazardous goods approved
UN-certified bags, tested and marked to carry UN-classified hazardous goods.
Product description
We hold UN certification on approved designs. A UN certified bag has been through documented drop, topple, righting and stacking tests, often by a third-party independent laboratory, and carries a UN marking that records the class of goods it is approved for, the weight and the year of manufacture.
The certification adheres to a unique design manufactured at a specific location. Changing construction, fabric weight or loop configuration invalidates it, which is why a UN bag is specified as a whole rather than assembled from options.
Uses
- Solid hazardous goods in UN packing groups II and III
- Material moving under IMDG, ADR or DOT rules
- Waste and reclaim classified as hazardous
Do not use
- Liquids, a UN FIBC is certified for solids
- Any class the specific design was not tested against
Important
Never assume a bag is UN certified because it looks like one. The marking is the certification; a bag without it has not been tested, whatever its construction.
Configurable options
Everything below is specified per order. Nothing here is a fixed catalogue number.
| Construction | As approved for the design |
|---|---|
| Static type | A, B, C or D as the material requires |
| Liner | Where the classification permits |
| Top | Spout or duffle |
| Bottom | Flat or spout |
| Add-ons | Document pouch, hazard marking, custom print |
Customizable options
Every option below is available on this product. They change how the bag fills, lifts and empties.
Lift loops
Corner loops
One loop sewn into each corner seam. The standard build, and the most affordable way to lift a bag.
Cross corner
Sewn into eight points across opposite corners, so the loops stand upright and the forklift operator is not fishing for four floppy straps.
Tunnel loops
A sleeve of body fabric spanning each side, corner to corner. The forks go straight through: the easiest pick where headroom is tight.
Stevedore straps
Double-layer straps across the corner loops, so the bag can be taken on one or two points instead of all four.
Double loops
Two lifting points instead of four, where that suits the load and the lift better.
Top
Spout top
A cylindrical spout sewn into the top panel. 14 in diameter by 18 in long as standard, sized to your filling head.
Spout top with flap
A spout top with a flap panel over it, tied down so the spout stays covered in transit.
Duffle top
A skirt the full width and depth of the bag, so the top opens completely and ties closed.
Flap top
A closed panel with a flap sewn along one seam, tied down over the mouth.
Open top
No panel at all. Fastest to fill where dust and weather are not a concern.
Conical spout top
A top panel that tapers up into the spout. Double spout tops are available too, specified to your filling equipment.
Bottom
Discharge spout
The standard 14 by 18 in spout, tied off. A wider spout is worth specifying for material that bridges.
Flat bottom
Closed base for product that is emptied by tipping or cutting.
Full bottom discharge
The whole base opens, for material that will not flow through a spout.
Spout protection
A flap, or a petal or iris closure, over the discharge, for when the spout must stay clean in transit.
Conical discharge spout
The base narrows into the spout, which helps product that is slow to flow empty completely. Specified to your equipment.
Add-ons
Baffles
Corner panels that hold a cube instead of a bulge: roughly 25 to 30% more volume in the same footprint, and it stacks safely.
Sift-proof seams
Filler cord sewn into the seam, for product fine enough to work through the stitching.
Document pouch
A sealed pouch for the paperwork which needs to travel with the bag.
Safety bands
A reinforcing band around the top, for added strength at the lift.
Custom print
Up to four sides, for branding and traceability on the line.
Liner
No liner
Fabric alone, where the product needs no barrier. The cleanest liner is the one you never have to specify.
Loose liner
Dropped in, not attached. Affordable insurance against fine powder finding the seams.
Glued-in liner
Bonded to the bag so it stays in place through filling and discharge, which is what a food or pharmaceutical audit expects to see.
Antistatic liner
Specify this inside a Type C or Type D bag, so the liner carries the same static classification as the fabric.
Foil liner
Designed for product that is filled hot, the foil laminate holds temperatures that would deform a polyethylene liner.
Fabric
Uncoated
Breathable, and the default build.
Coated
A thin polypropylene coat over the weave, for fine powder and moisture resistance.
Frequently Asked Questions
Does UN certification cover any hazardous material?
No. The certification names the packing group and the class of goods the design was tested against. Tell us what you are moving and we will confirm whether an approved design covers it.
Can I change the spec on a UN certified bag?
Not without re-testing. The approval belongs to the design as tested, so construction, fabric and loops are fixed. Printing and document pouches do not affect it.
Do I still need a Type C or Type D?
Quite possibly. UN certification covers mechanical performance, not static. If the material is a flammable powder, the static type is specified separately and both apply.

Material, fill weight, how you fill and how you discharge. That is enough for us to come back with a specification.
