The heavy-equipment shipper’s surprise: the machine itself is the dangerous goods. An excavator, a loader, a generator, an e-scooter, a fork lift — if it has a fuel system or a battery, it moves as Class 9 dangerous goods. Not the fuel drained into a separate drum; the vehicle. Here’s how that works and what carriers require.
Why a whole machine is “dangerous goods”
In transport terms the hazard isn’t the machine working — it’s the fuel in the tank and the energy in the battery sitting in a container or a hold. So the regulations assign vehicles and self-propelled equipment their own UN numbers, based on what powers them:
- UN3166 — Vehicle, flammable liquid / flammable gas powered, or fuel cell. The combustion case: anything with a petrol or diesel engine — cars, loaders, generators, compressors.
- UN3171 — Battery-powered vehicle or equipment. Historically the wet-battery / non-lithium case.
- UN3556 — Vehicle, lithium-ion battery powered (and UN3557 for lithium-metal, UN3558 for sodium-ion). The electric case: EVs, e-scooters, battery machinery.
A machine that has both an engine and a lithium battery is classified by the rules for the combination — get it identified correctly before booking.
What carriers require
Acceptance of a powered vehicle or machine turns on a few practical points:
- Fuel management. Carriers set limits on how much fuel may remain and require the system to be secured against leaks; some lanes want tanks near-empty. The exact rule depends on mode and carrier.
- Battery security. Terminals disconnected or protected against short circuit, batteries secured against movement, lithium batteries meeting their own Class 9 requirements — see the lithium guide.
- Securing and no leaks. The machine braced so it can’t shift, with no fluid leaks.
- A dangerous-goods declaration where required, matching the machine’s actual configuration.
Where DG meets project cargo
Powered equipment is often also oversized — an excavator or crane is both Class 9 and out-of-gauge. That means the DG rules and the project-cargo rules apply at once: the right UN classification and fuel/battery handling, and flat-rack or breakbulk ocean, permits, escorts and rigging for the dimensions. Handled by separate vendors, that’s where things fall between the cracks — the DG desk doesn’t know the machine is over-width, the heavy-haul team doesn’t know the tank rules.
This is exactly the combination we run as one file — powered machines that are also oversized, on a show deadline, moved from port to booth with DG classification and dimensions on one critical path. See our project & expo logistics →
Before you book
Know the power source (engine, lithium, other), the fuel state you can ship in, the machine’s dimensions and weight, and the deadline. Then it’s one conversation, not three. Send us the equipment details and we’ll classify it, plan the move, and quote the whole thing together.
