Air vs sea freight from China for small shipments
Shipping methods · Updated
For small China to USA shipments the choice is almost always air freight or sea LCL (less than container load). Picking the right one is the biggest lever you have on cost and speed.
Here is how to decide without overthinking it.
Air freight: fast, predictable, priced by weight
Air freight moves your cargo in roughly 5 to 10 days door to door. It is priced mostly by chargeable weight, so it stays economical while your shipment is light, and it gets expensive fast as weight climbs.
Choose air when the load is time-sensitive, when it is light (under about 200 kg), or when tying up cash in slow-moving inventory hurts more than the freight bill.
Sea LCL: cheaper per kilo, slower, more steps
Sea LCL shares a container with other shippers, so you pay only for the space you use. Per kilo it is far cheaper than air, but transit runs roughly 30 to 45 days door to door and there are more handoffs at the ports.
Choose sea when the load is heavier (200 kg and up), not urgent, and you can plan inventory far enough ahead to absorb the longer transit.
A simple rule of thumb
Under about 150 to 200 kg, air is usually competitive and far faster, so it tends to win. Above that, sea LCL usually wins on total cost unless you need the goods quickly.
Duty is the same either way, since it is based on the goods, not the transport. So compare the freight portion and the value of getting inventory sooner.
FAQ
Is air or sea cheaper for a small shipment from China?
Per kilo, sea LCL is cheaper. But for light loads under roughly 150 to 200 kg, air is often competitive once you account for handling, and it arrives weeks sooner. Above that weight, sea usually wins on total freight cost.
How long does each method take from China to the USA?
Air freight is roughly 5 to 10 days door to door. Sea LCL is roughly 30 to 45 days door to door, depending on ports, sailing schedules, and customs.
Does the shipping method change my import duty?
No. Duty is based on the value and classification of the goods, not how they travel. Air and sea incur the same duty; only the freight cost and transit time differ.
