Dangerous Goods Screener

Find out at quoting time — not at the terminal — whether what you are shipping is regulated for air transport, and which class it falls under.

This is an early-warning lookup, not a compliance determination. The IATA Dangerous Goods Regulations are the authority: they carry the packing instructions, quantity limits per package, UN numbers, and the state and operator variations that decide whether a specific commodity may fly. Shipping dangerous goods by air requires current DGR training and a Shipper's Declaration. Nothing on this page substitutes for either — when in doubt, declare it and let the carrier confirm acceptance.

The nine classes

21 classes and divisions. Air freight's own troublemakers — lithium batteries, dry ice, magnetised material — all live in Class 9.

1

Explosives

Substances and articles that can explode, project fragments or burn energetically.

1.1 Mass explosion hazard Cargo aircraft only

Explodes as a whole.

e.g. Blasting explosives, Detonating cord

1.2 Projection hazard Cargo aircraft only

Projects fragments without mass explosion.

e.g. Certain munitions

1.3 Fire hazard Cargo aircraft only

Burns energetically, minor blast.

e.g. Propellant, Display fireworks

1.4 No significant hazard Restricted

Effects largely confined to the package.

e.g. Safety cartridges, Small-arms ammunition

1.4S is the only division routinely accepted on passenger aircraft, and only within DGR limits.

1.5 Very insensitive, mass explosion Cargo aircraft only

Insensitive but mass-explosion capable.

e.g. Blasting agents

1.6 Extremely insensitive Cargo aircraft only

No mass-explosion hazard.

e.g. Specialist articles

2

Gases

Compressed, liquefied, refrigerated or dissolved gases.

2.1 Flammable gas Restricted

Ignites in air at low concentration.

e.g. Butane lighters, Aerosols (flammable), Propane

2.2 Non-flammable, non-toxic gas Restricted

Asphyxiant or oxidising, not flammable.

e.g. Nitrogen, Helium, Fire extinguishers, Carbon dioxide cylinders

2.3 Toxic gas Cargo aircraft only

Toxic or corrosive by inhalation.

e.g. Chlorine, Certain fumigants

3

Flammable liquids

Liquids with a flash point at or below 60 °C.

3 Flammable liquid Restricted

Gives off ignitable vapour at ambient temperature.

e.g. Paint, Solvents, Perfume and alcohol-based cosmetics, Adhesives

Packing group drives the quantity limit — PG I is far more restricted than PG III.

4

Flammable solids

Solids that ignite readily, self-heat, or react with water.

4.1 Flammable solid Restricted

Readily combustible or may cause fire through friction.

e.g. Matches, Sulphur, Metal powders

4.2 Spontaneously combustible Restricted

Self-heats or ignites on contact with air.

e.g. White phosphorus, Oily rags, Some fishmeal

4.3 Dangerous when wet Restricted

Emits flammable gas on contact with water.

e.g. Calcium carbide, Sodium, Some battery cores

5

Oxidisers and organic peroxides

Substances that yield oxygen and intensify a fire, or are thermally unstable.

5.1 Oxidising substance Restricted

Feeds a fire even without air.

e.g. Hydrogen peroxide solutions, Ammonium nitrate fertiliser, Pool chemicals

5.2 Organic peroxide Restricted

Thermally unstable, may need temperature control.

e.g. Hardeners, Curing agents

Some types require temperature control in transit and are forbidden by air entirely.

6

Toxic and infectious substances

Substances harmful by ingestion, inhalation or skin contact, and biological material.

6.1 Toxic substance Restricted

Poisonous to humans.

e.g. Pesticides, Arsenic compounds, Cyanides

6.2 Infectious substance Restricted

Contains or may contain pathogens.

e.g. Category A and B diagnostic specimens, Clinical waste, Cultures

Category A infectious substances have their own packaging and notification requirements.

7

Radioactive material

Material with an activity concentration above the DGR exemption threshold.

7 Radioactive material Restricted

Excepted, Type A, Type B or fissile packages.

e.g. Medical isotopes, Industrial gauges, Radiopharmaceuticals

Transport index and criticality safety index limits govern how much can go on one aircraft.

8

Corrosives

Substances that attack skin, metal or other cargo.

8 Corrosive substance Restricted

Destroys living tissue or corrodes metal.

e.g. Battery acid, Sodium hydroxide, Some cleaning agents, Wet cell batteries

9

Miscellaneous dangerous goods

Regulated hazards that do not fit classes 1 to 8 — the class most shippers meet without expecting to.

9 Miscellaneous Restricted

Anything presenting a hazard in air transport not covered elsewhere.

e.g. Dry ice (UN1845), Magnetised material, Aviation-regulated liquids, Engines and machinery containing fuel

9A Lithium batteries Restricted

Lithium ion (UN3480/UN3481) and lithium metal (UN3090/UN3091) cells and batteries.

e.g. Power banks, Laptops and phones, E-bike and scooter batteries, Battery-powered equipment

The single most common reason a shipment is stopped at acceptance. Standalone lithium ion (UN3480) is cargo-aircraft-only and must be shipped at a state of charge not exceeding 30%. Batteries in or with equipment follow different rules again.

Frequently asked

Does an empty result mean my cargo is not dangerous goods?

No. This screener matches keywords against a class summary and a handful of examples. Plenty of regulated commodities are not in that list, and classification depends on the substance, its concentration and its packing — not on its name. The safety data sheet and the IATA DGR decide, not this page.

Can I ship dangerous goods by air at all?

Most classes can fly, within limits. Some divisions are cargo-aircraft-only, some are forbidden outright, and every acceptance depends on the operator and the states along the route. A declaration and correctly marked, certified packaging are mandatory.

Do I need training to ship dangerous goods?

Yes. Preparing a dangerous goods shipment for air transport requires current, role-specific training under the IATA DGR. An untrained shipper cannot legally complete a Shipper’s Declaration, and getting it wrong carries real liability.

Why are lithium batteries such a problem?

They are the most common regulated item shippers do not realise is regulated, and they behave badly in a fire. Standalone lithium ion batteries (UN3480) are cargo-aircraft-only and must ship at a state of charge no higher than 30%. Batteries inside or packed with equipment follow different rules again, which is where most mistakes happen.
