Air Freight or Ocean Freight From Asia? How to Choose
Air is fast and expensive, ocean is slow and cheap, and the right answer depends on weight, volume, value and how much a late shipment would cost you. A practical way to decide shipment by shipment.

Most importers default to ocean and switch to air in a panic when a launch date slips. That works, but it is expensive. Deciding properly, shipment by shipment, comes down to four things: how heavy and bulky the goods are, what they are worth, how soon you need them, and what it costs you if they are late.
| Ocean (LCL) | Ocean (FCL) | Air freight | |
|---|---|---|---|
| Typical transit | Several weeks, plus consolidation time | Several weeks | Days |
| Priced on | Volume or weight, per cubic metre | Per container | Chargeable weight, per kilo |
| Best for | Small or mixed shipments | Shipments that fill most of a container | Urgent, light or high-value goods |
| Main risk | Delays at consolidation and deconsolidation | Paying for space you do not fill | Cost on bulky goods |
Understand chargeable weight
Air carriers charge for whichever is greater: the actual weight of the shipment or its volumetric weight, worked out from the carton dimensions. For standard air freight the usual formula is length by width by height in centimetres, divided by 6,000; express couriers often divide by 5,000, which makes light, bulky goods more expensive still. A carton of cushions that weighs 8 kg may be charged as 25 kg or more. Always ask your forwarder for the chargeable weight, not just the rate per kilo.
LCL or a full container?
By sea, small shipments travel LCL (less than container load), consolidated with other importers' goods and priced per cubic metre. Once a shipment fills a good part of a container, a dedicated FCL (full container load) is often cheaper overall and faster, because it skips the consolidation and deconsolidation steps. A 20-foot container holds roughly 33 cubic metres in theory, though in practice you will load less. Ask your forwarder to quote both whenever you are near the line.
Split the shipment
If a delay leaves you short of stock, ship just enough by air to cover the weeks until the ocean shipment lands, and send the rest by sea. You pay the air premium on a fraction of the order instead of all of it.
Price the cost of being late
The freight bill is only half the comparison. If goods arriving three weeks later means a missed season, a stockout on your best seller or a lost retail slot, that cost belongs in the calculation too. Air also reduces the stock you have tied up in transit, which matters when cash is tight. For low-value, bulky goods the maths almost always favours ocean; for small, valuable or time-critical goods, air can be the cheaper choice once you count everything.
The cheapest freight is the one you booked early enough not to need the expensive one.
