Most importers do not find out their cargo is hazardous when they buy it. They find out when the shipping line rejects the booking, when the shipment is held at origin, or when the airline asks for documents nobody has.
And it is rarely about industrial chemicals. It is about products you can buy in any shop: a perfume, a deodorant, a can of paint, a speaker with a battery. In international transport, all of those are dangerous goods.

Why everyday items are "dangerous"
The classification does not measure how risky a product is in your home. It measures how risky it is inside a sealed container or in an aircraft hold: no ventilation, changes in pressure and temperature, stacked among thousands of packages, with nobody able to intervene for days.
An aerosol in your bathroom is harmless. The same aerosol at 10,000 metres, with cabin pressure dropping, is a pressurised vessel that can burst. That is why the rules do not look at the product: they look at the product in transit.
The products that surprise people most
These come up again and again in held shipments:
| Product | Why it is regulated | Usual class |
|---|---|---|
| Perfumes and colognes | High alcohol content | 3 — Flammable liquids |
| Aerosols and deodorants | Pressurised containers | 2 — Gases |
| Paints, varnishes and thinners | Flammable solvents | 3 — Flammable liquids |
| Lighters and refills | Pressurised liquefied gas | 2 — Gases |
| Industrial cleaning products | Corrosive acids or alkalis | 8 — Corrosives |
| Strong magnets (neodymium) | Interfere with aircraft navigation | 9 — Miscellaneous |
| Lithium batteries (in any device) | Thermal and fire risk | 9 — Miscellaneous |
| Lead-acid batteries | Corrosive electrolyte | 8 — Corrosives |
| Nitrate fertilizers | Oxidizers | 5 — Oxidizers |
| Pesticides and agrochemicals | Toxicity | 6 — Toxic |
| Medical and biological samples | Infectious risk | 6 — Infectious |
| Used engines and machinery | Residual fuel and oil | Depends on residues |
The class shown is the usual one for that family of products. The actual classification of your specific item is defined by its safety data sheet, because it depends on the exact composition: two paints from different brands can be classified differently.
The most common case: anything with a battery
If we had to name a single cause of held shipments, this would be it. Lithium batteries are class 9, and they are inside practically everything imported today:
- Consumer electronics: laptops, phones, tablets, headphones, speakers
- Cordless tools and their spare parts
- Scooters, e-bikes, skateboards
- Power banks, rechargeable lights, cameras
- Appliances with battery backup
- Electronic toys
The detail that catches people out: it does not matter that the battery is inside the device. It is still regulated, simply under a different UN number. How each case is declared is covered in the guide to importing lithium batteries.
How to check whether yours qualifies
Do not guess, and do not decide it yourself. There is a direct way:
- Ask your supplier for the safety data sheet (SDS or MSDS). Every serious manufacturer has one.
- Go to section 14, transport information.
- If a UN number and a class appear there, your product is dangerous goods. If it says "not regulated" or "not restricted", it is not.
That document is the only answer that counts, and it is the one the carrier will read. What it is and how to request it is explained in the UN38.3 and safety data sheet guide.
What happens if you do not declare it
Sometimes out of ignorance, sometimes to avoid the paperwork, some people declare the cargo as ordinary. The consequences escalate:
- Rejection at origin. If it is detected at loading, the shipment does not sail and you lose the booked space.
- Hold at destination. If it is detected on arrival, the cargo is immobilised while it is regularised, accruing storage charges.
- Fines and liability. Misdeclaring dangerous goods is an offence, and liability sits with whoever declares.
- The real risk. Fires on container ships caused by misdeclared dangerous goods are a well-known industry problem. This is not bureaucracy: the rules exist because accidents happened.
And there is a practical point: cargo insurance may not respond if the goods were misdeclared.
What to do if yours is on the list
Your product being dangerous goods does not mean it cannot be brought in. It means it moves along a different path, with documentation and prior approval.
What changes:
- The shipment needs approval from the shipping line or airline before it can be booked. How that process works is covered in what your shipment needs in order to be approved.
- Packaging must be UN-approved for that class, and packages correctly labelled.
- Lead times are longer: you need to book further in advance.
- The mode matters: air freight is considerably more restrictive than ocean freight.
Frequently asked questions
Is perfume considered dangerous goods?
Yes, usually. Perfumes and colognes have a high alcohol content, which typically classifies them as a flammable liquid (class 3). It is one of the products that most surprises first-time importers, because it is bought completely normally in any shop.
Can I import products containing lithium batteries?
Yes. Lithium batteries are class 9 and are transported regularly, but they require specific documentation — including the UN38.3 test summary — and prior approval from the carrier. This applies equally when the battery comes inside the equipment, simply under a different UN number.
How do I know for certain whether my product is hazardous?
Ask your supplier for the safety data sheet and look at section 14. If there is a UN number and a hazard class, it is. If it states "not regulated" for transport, it is not. That sheet is what the shipping line or airline will review.
What happens if I misdeclare the goods?
It can end in rejection of the shipment at origin, holds and storage charges at destination, fines, and cargo insurance not responding in the event of an incident. It is also the cause of serious vessel accidents, which is precisely why these rules exist.
Is dangerous cargo more expensive to import?
It usually involves additional costs for documentation, approved packaging and special handling, and lead times are longer because bookings need to be made in advance and approval awaited. How much exactly depends on the class, the quantity and the route.
