Chargeable Weight in Air Freight
How carriers compare actual gross weight against volumetric weight — and why understanding this calculation is the first step to an accurate quote.
Read the article →This is where we bring together everything that matters when cargo is too large, too heavy or too valuable to move as standard freight — mining machinery, power infrastructure, aerospace components, oil and gas equipment and the project cargo that keeps Australia's industrial projects on schedule. Whether you're new to air freight or you've booked a hundred charters, this hub is built to give you a genuinely useful starting point, with every guide on the site organised and linked from here. For shipments that need hands-on coordination from day one, working with experienced heavy air cargo services is usually what turns a complex movement into a straightforward one.
Moving heavy or oversized cargo by air follows a fairly consistent rhythm, even though every shipment is different. Here's the shape of it, start to finish.
Weight, dimensions, value and fragility are measured against what's actually achievable — this decides which aircraft, doors and handling gear are even in play.
Routing, aircraft selection, documentation and ground handling equipment are locked in well ahead of departure, not left to be sorted at the ramp.
Warehousing, road transport, airside loading, customs and destination handling are lined up so no single link stalls the rest of the journey.
Real-time tracking and insurance stay active in the background, so any issue is caught in transit — and the final leg to site is confirmed, not assumed.
Four questions cover most of what a shipper needs to know before their first heavy air cargo booking.
There's no single industry-wide cut-off. Most operators start treating a shipment as heavy or oversized once a single piece exceeds roughly one tonne, or once its dimensions exceed a standard pallet or unit load device — see the full definition in our pillar guide.
Ocean freight is almost always cheaper per kilogram, but air freight earns its cost through speed and fewer handling cycles — the right call when the cost of delay outweighs the price gap. We break this down properly in air freight versus ocean freight for heavy cargo.
It runs on coordination — aircraft, ground equipment, documentation, customs and insurance all have to line up, particularly for shippers handling this kind of freight for the first time. See the full pillar guide for how each piece fits together.
Heavy air cargo serves mining, energy, construction and aerospace projects worldwide, with a strong Australian dimension — Sydney, Melbourne, Brisbane, Perth and Adelaide each have different freighter capacity, and remote sites often need a substantial road leg either side of the flight.
Our pillar guide brings together aircraft selection, cost, compliance, handling equipment, insurance and risk into one practical reference — then links out to twelve detailed guides covering every part of the process in depth.

Air Freight & Heavy Cargo Specialist
Theodore writes independent, practical guidance on air cargo, heavy freight and global logistics infrastructure, with a particular focus on how shipments actually move between Australia and the rest of the world. Every guide on this site is built from real operational detail — aircraft limitations, ground handling realities, documentation requirements and the trade-offs shippers face on genuine projects — rather than generic freight theory.
