Air freight from China: costs, transit and when it is worth it

Air freight is usually chosen for the wrong reason: someone is late. It is a legitimate reason, and it is also why so many businesses pay air rates on goods that never justified them. Air freight is priced on a completely different basis from sea freight, and understanding that basis is what turns it from an emergency expense into a deliberate choice.

How it is priced

Air freight is quoted per kilogram of chargeable weight, and chargeable weight is the greater of two numbers: what the shipment actually weighs, and what its volume says it should weigh. Light, bulky cargo is charged on its volume rather than on the scale reading.

This has a practical consequence that surprises people. Reducing carton size can cut an air freight bill more than reducing weight does, because it is the volumetric figure that is setting the price. Before you book, it is worth asking your supplier whether the cartons can be packed tighter.

Rates move with fuel cost and with season, and peak periods before major holidays move them hard. Any page publishing a fixed per-kilogram figure is publishing a number that was true once.

The last three are where a cheap-looking quote becomes an expensive shipment. A quote that ends at the destination airport is not a quote to your door, and the difference is not small.

What the transit actually consists of

The flight is rarely the long part. Four stages sit between a finished production run and goods on your shelf, and only one of them is airborne.

• Export handling at origin, booking, documentation and delivery to the airport
• The flight, the part everyone thinks of, and the most predictable
• Customs clearance at destination, the stage with the widest variance by far
• Domestic delivery, from the arrival airport to where the goods are going

Clearance is why air freight is quoted per booking rather than as a published number. It depends on the commodity, the classification, the completeness of the paperwork and whether the entry gets examined. Publishing one figure for it would be inventing it, so we do not.

Per-parcel services are a different matter, because they are one company end to end. On the China to United States lane we see 6 to 12 days on standard service and 3 to 5 on express, destination-dependent within the US — ranges from our own shipments, not a guarantee.

The value-per-kilogram test

One question decides most air-versus-sea calls: what is a kilogram of this cargo worth? Air freight costs a multiple of sea freight per kilogram, so the question is whether your goods carry enough value per kilogram to absorb it.

The split is legitimate and underused: air-freight part of a run so you can start selling, sea-freight the rest so the bulk of the order costs what it should. Very few sellers ask for this and most forwarders will quote it.

Air freight or express?

These are often conflated and they are different products. Express is door-to-door: one company carries the goods, handles the customs entry and delivers, and is accountable for the whole chain. Air freight is airport-to-airport capacity, with clearance and delivery arranged around it.

Express costs more per kilogram and is dramatically simpler. Air freight is cheaper as volume rises and needs someone managing it. The crossover depends on the shipment, which is why both belong in the same quote rather than being treated as separate decisions.

What to fix in writing before booking

• Chargeable weight, confirmed from actual carton dimensions rather than estimated
• What the quote includes, specifically whether clearance and destination delivery are in it
• Who carries the duty, which is the incoterms decision — DDP is the option worth understanding before you need it
• The classification, because it sets the duty rate and a wrong one is expensive to correct
• The date it has to land, which often decides the mode on its own

Air and sea freight from China sets the modes out side by side, including how parcel services compare for per-order shipping, and shipping from China to the USA covers what drives transit variance on that lane.
