Planning on shipping dangerous goods to Australia? Whether you are an e-commerce brand sending battery-powered gadgets, a manufacturer importing industrial adhesives or a supplier moving perfumes and aerosols, dangerous goods (DG) are among the most tightly regulated cargo in international freight.
Your shipment has to satisfy international transport rules (the IATA Dangerous Goods Regulations for air and the IMDG Code for sea) and Australian rules once it lands, including the Australian Dangerous Goods (ADG) Code for road and rail. A single mistake in classification, packaging, labelling or documentation can see your cargo rejected by the carrier, held at the border, fined or even destroyed.
This guide walks you through the essentials: what counts as dangerous goods, the nine DG classes, packing groups, the regulators involved, the documents you need, lithium and sodium-ion battery rules, how air and sea compare, and what drives the cost of a DG shipment.
This guide is general information only, not legal or compliance advice. Always confirm requirements with a qualified dangerous goods professional before you ship.
Dangerous goods (also called hazardous materials or HazMat) are articles or substances that can pose a risk to health, safety, property or the environment during transport.
Before you book anything, confirm whether your cargo is classified as DG. The quickest way is to check Section 14 (Transport Information) of the product's Safety Data Sheet (SDS). If a UN number is listed there, you are dealing with dangerous goods.
Many importers are surprised to learn how many everyday products are regulated as DG. If you ship any of the following, check the classification carefully:
Shipping undeclared DG is a serious breach of transport law. If you label a carton of perfume as "beauty supplies" without declaring that it contains alcohol (a flammable liquid), you are putting the aircraft or vessel, its crew and every other shipper's cargo at risk.
Consequences can include:
Correct classification is the foundation of shipping dangerous goods to Australia. The United Nations system divides DG into nine classes, and every transport code (IATA DGR, IMDG Code and ADG Code) uses the same structure. Use the table below to see where your product is likely to fit, then confirm it against the SDS.
| Class | Name | Description | Common examples | Typical UN numbers |
|---|---|---|---|---|
| Class 1 | Explosives | Substances and articles capable of rapid combustion or explosion. | Fireworks, flares, ammunition, detonators. | UN 0336, UN 0012 |
| Class 2 | Gases | Compressed, liquefied or dissolved gases. | 2.1 flammable (propane); 2.2 non-flammable, non-toxic (fire extinguishers); 2.3 toxic (chlorine). | UN 1950 (aerosols), UN 1044 |
| Class 3 | Flammable liquids | Liquids that give off flammable vapour. | Paint, perfume, alcohol, adhesives, petrol, acetone. | UN 1263 (paint), UN 1266 (perfumery products) |
| Class 4 | Flammable solids | Solids that burn easily, combust spontaneously or react dangerously with water. | 4.1 matches; 4.2 white phosphorus; 4.3 sodium (dangerous when wet). | UN 1325, UN 1381 |
| Class 5 | Oxidising substances and organic peroxides | Substances that release oxygen and increase fire risk. | 5.1 hydrogen peroxide; 5.2 organic peroxides (resin hardeners). | UN 2014, UN 3105 |
| Class 6 | Toxic and infectious substances | Substances liable to cause death or serious harm to health. | 6.1 pesticides, arsenic compounds; 6.2 medical waste, infectious samples. | UN 2811, UN 2900 |
| Class 7 | Radioactive material | Materials that emit ionising radiation. | Medical isotopes, nuclear density gauges. | UN 2915, UN 3332 |
| Class 8 | Corrosives | Substances that damage materials or living tissue on contact. | Sulfuric acid, wet-cell car batteries, bleach, mercury. | UN 2794, UN 1791 |
| Class 9 | Miscellaneous dangerous goods | Hazards not covered by the other classes. | Lithium and sodium-ion batteries, dry ice, magnetised material, environmentally hazardous substances. | UN 3480, UN 3551, UN 1845 |
Tip: Among Australian imports, Class 3 (flammable liquids such as perfume and paint) and Class 9 (batteries) are two of the classes importers deal with most often.
If you are unsure about any of the acronyms in this guide, our shipping terms and acronyms glossary explains them in plain English.
Once you know the class, you need the packing group (PG). It shows the degree of danger within most classes and determines how strong the packaging must be.
The correct PG for your product is shown on the SDS and in the dangerous goods list of the relevant code. Don't guess it from a similar product, because closely related substances can sit in different groups.
When shipping dangerous goods to Australia, you can't simply put the items in a standard cardboard carton. Most DG must travel in UN specification packaging, often called UN-certified boxes or drums.
This packaging has passed performance tests such as drop and stacking tests, and it carries a UN specification marking that shows the packaging type, the packing groups it is approved for and where it was certified. For example, a marking beginning with 4G identifies a fibreboard box. The packaging must be rated for your product's packing group and used exactly as tested.
Dangerous goods shipments to Australia sit inside a "compliance stack". You need to satisfy the international rules for the transport mode, then the Australian rules that apply at the border and once your goods move inland.
Your customs broker manages the import declaration side of the process. For more on that, see our step-by-step guide to customs clearance in Australia.
Paperwork problems are one of the most common reasons DG shipments are rejected or delayed. When shipping dangerous goods to Australia, a standard commercial invoice and packing list are not enough. Use this checklist to make sure you have the complete paper trail.
Warning: don't fill out a DGD yourself unless you are trained and authorised to do so. It is a legal declaration, and errors can lead to enforcement action.
Documentation errors are also a common cause of delays at the Australian border. Our guide to common customs clearance delays in Australia covers how to avoid them.
Batteries are the DG that importers encounter most often, and the rules change more often than for most other classes. Keep these points in mind:
IATA publishes battery guidance documents for shippers on its batteries page, which is a good starting point before you talk to your forwarder.
| Battery configuration | UN number | Packing instruction (air) | Key constraint |
|---|---|---|---|
| Batteries on their own (power banks, spare batteries) | UN 3480 (lithium-ion); UN 3551 (sodium-ion) | PI 965; PI 976 | Lithium-ion batteries under UN 3480 are forbidden on passenger aircraft and must travel Cargo Aircraft Only (CAO), at a limited state of charge. Check the current DGR for the equivalent sodium-ion restrictions. |
| Packed with equipment (battery separate, in the same box) | UN 3481 (lithium-ion); UN 3552 (sodium-ion) | PI 966; PI 977 | Can travel on passenger aircraft if the per-package limits in the packing instruction are met. |
| Contained in equipment (installed in a laptop or phone) | UN 3481 (lithium-ion); UN 3552 (sodium-ion) | PI 967; PI 978 | Generally the least restrictive configuration. Smaller batteries and quantities that meet the packing instruction's limits may qualify for reduced marking and documentation. |
Key requirement for Australia: make sure your supplier can provide the UN 38.3 test summary for every battery type. Airlines, forwarders and Australian authorities may request it to confirm the battery design is safe for transport.
Follow this workflow to keep your shipment safe and compliant from origin to delivery.
Request the current SDS from the manufacturer and check Section 14. Note the UN number, proper shipping name, class and packing group. If there is a UN number, the product is DG.
Not every logistics provider accepts DG, and not every carrier accepts every class. Work with a forwarder that has experience with dangerous goods and can tell you early whether your cargo can move by air, by sea or both. Our guide on how to choose the best freight forwarder in Australia lists the questions worth asking.
Submit your DGD, SDS and any battery test summaries to your forwarder and carrier for checking. Carriers review DG bookings before acceptance, a step often called the "DG check" or acceptance check.
Once accepted, the goods are collected and moved to the port or airport for export. On arrival in Australia, your customs broker lodges the import declaration and manages any border or biosecurity requirements through customs and quarantine clearance. Inland delivery must then follow the ADG Code and state or territory laws. Vehicles and drivers carrying larger quantities of DG may need dangerous goods licences.
Choosing between air and sea for DG isn't only about speed and cost. It is also about what each mode legally allows.
| Feature | Air freight (IATA DGR) | Sea freight (IMDG Code) |
|---|---|---|
| Speed | Generally the faster option. Transit times depend on the route, carrier and flight availability, DG acceptance checks and customs clearance. | Generally slower than air. Transit times depend on the route, vessel schedules, transhipment, port conditions and customs clearance. |
| Cost | Usually higher per kilogram, with DG handling charges that depend on the class and quantity. | Usually more economical for larger volumes, with DG charges that depend on the class, container type and carrier. |
| Restrictions | The strictest mode. Many items are forbidden on passenger aircraft or allowed on cargo aircraft only. | Less restrictive overall. Allows larger quantities and a wider range of classes, subject to segregation rules. |
| Packaging | Tighter quantity limits per package. | Larger quantities per package are often permitted. |
| Best for | Urgent samples, high-value electronics, medical isotopes. | Bulk chemicals, large industrial batteries, palletised paint. |

When you ship DG, the base freight rate is only part of the picture. DG-specific charges vary from shipment to shipment, so it pays to understand what drives them before you request a quote:
Overall, a DG shipment usually costs more than an equivalent general cargo shipment. How much more depends on the class, quantity, packaging, mode, route, carrier acceptance and prevailing market conditions. It is also worth reviewing your cover; our guide to freight insurance explains what to check.

The examples below are illustrative. They show the kinds of problems that regularly affect DG shipments.
What happened: an overseas beauty brand sends a carton of perfume to Sydney by air, described only as "cosmetics". The issue: perfume contains alcohol and is usually a Class 3 flammable liquid. The consequence: the carrier identifies the undeclared DG, the shipment is pulled from the flight and reported, and the shipper faces enforcement action, extra handling and the cost of returning or disposing of the goods. The fix: declare the goods under UN 1266 (perfumery products), use compliant packaging and, where the inner bottle sizes allow, ship under the "Limited Quantity" provisions.
What happened: an e-bike is shipped from China to Melbourne, with the battery packed separately from the bike, which makes it a standalone lithium-ion battery (UN 3480). The issue: UN 3480 batteries are forbidden on passenger aircraft, but the shipment was booked on a passenger flight. The consequence: the shipment is rejected at the origin airport. The fix: rebook on a Cargo Aircraft Only (CAO) service, which usually costs more, or check whether sea freight is a better option for the battery.
If your goods are held on arrival, see what happens when customs seizes a shipment.
There is no single "DG import licence" for general dangerous goods such as paint or batteries. However, your business generally needs to be registered with AICIS if you import industrial chemicals. Some goods, such as explosives (Class 1) and radioactive material (Class 7), need specific permits or licences from Australian authorities before import, and DG transport within Australia may require licences under state and territory law.
Postal services place strict limits on dangerous goods, and most DG cannot be sent through international post. Check Australia Post's dangerous and prohibited goods guidance before posting anything. For commercial DG shipments, use a freight forwarder or a courier service that accepts the goods you are shipping.
Limited Quantity (LQ) provisions let you ship small amounts of some DG with simpler packaging and labelling requirements. For example, small bottles of perfume are easier to ship than a large drum of the same product. Qualifying packages carry the limited quantity mark, a diamond with black top and bottom corners. The air version of the mark also shows a "Y".
Failing to declare DG is an offence under Australian aviation and maritime laws. It can lead to penalties, prosecution, seizure or destruction of the goods and carrier restrictions. Consequences are more serious if the undeclared goods cause an incident or injury.
Look at the Safety Data Sheet (SDS) from your manufacturer and go to Section 14: Transport Information. If a UN number is listed, the product is a dangerous good. If there is no SDS, ask your supplier for one before you book.
The cost depends on the DG class and packing group, quantity, packaging, transport mode, route, carrier acceptance, documentation needs and prevailing market conditions. DG shipments usually cost more than general cargo because of extra checks, handling and packaging. Contact our team for a quotation based on your SDS and shipment details.
Transit times depend on the mode, route, carrier schedules, whether your goods can travel on passenger aircraft or need a cargo-only service, DG acceptance checks and customs clearance. Correct documents and packaging from the start help avoid avoidable holds. Ask us for a shipment-specific transit estimate.
Often, yes, but not always. Consolidators decide which DG classes they will accept in shared containers, and segregation rules may prevent some combinations. Check acceptance with your forwarder before your supplier packs the goods.
Shipping dangerous goods to Australia leaves no room for shortcuts. International air and maritime rules and Australian border and transport laws all apply, so getting the classification, packaging and documents right is what keeps your goods moving.
