Not every Yiwu order fills a container. Plenty of buyers start with a few cartons of samples, a trial order of one product, or a small top-up between sea shipments. For those, the sea is usually the wrong tool, and the real question becomes air. As a company doing Yiwu sourcing and shipping together, we send small consignments by air constantly, and the first thing worth learning is that “air” is not one service. It splits into express courier and air freight, and they behave differently in cost, speed and paperwork. This post walks through both, and through the traps that catch first-time shippers of small orders.
Express courier: the door-to-door parcel
Express is what most people picture. An international courier collects the cartons from the warehouse in Yiwu, and the same network delivers them to your door. You get a tracking number and, for most destinations, the goods arrive within days rather than weeks, though how many days varies with destination and season, so treat any figure as typical rather than promised.
The strengths are obvious. It is fast, it is simple, and there is exactly one party responsible from pickup to delivery. For sample parcels and very small orders it is usually the only option worth discussing. The weakness is the price curve. Express is priced per kilo, and as the weight climbs, the total climbs with it in a way that stops making sense well before you reach a pallet’s worth of goods.
Air freight: cheaper per kilo, more moving parts
Air freight is a different animal. Your cargo is booked onto a flight as freight, flies airport to airport, and is then collected or delivered by a separate arrangement at the destination end. Per kilo it is generally cheaper than express once the shipment has some real weight to it, which is why consignments in the tens or hundreds of kilos tend to migrate from courier to air freight.
The trade-off is that the journey has more parts. Someone has to truck the goods to the departure airport, someone has to clear and collect them at the arrival airport, and that someone at the arrival end is you or your appointed broker. Air freight is not door to door unless you pay to make it so. Buyers who expect a courier experience from an air freight booking are the single most common source of confusion we see with small shipments, so let me be blunt: with air freight, the goods land at an airport, and what happens next is your side of the job unless you have arranged otherwise.
Volumetric weight, the rule that surprises everyone
Air services do not charge on actual weight alone. They charge on whichever is greater, the actual weight or the volumetric weight, a figure calculated from the dimensions of the carton. The exact divisor used in the calculation is a standard industry convention that differs slightly between express and air freight, and your agent will quote using the right one. The principle is what matters: light, bulky goods are charged as if they were heavier, because they occupy space in an aircraft that dense cargo would pay for.
This has real consequences for Yiwu goods. A carton of stainless steel tools flies at its actual weight. A carton of inflatable pool toys or plush animals is mostly air, and it will be billed on volume, sometimes several times its weight on the scale. Two habits protect you. First, get the carton dimensions and weights from the warehouse before booking, and ask for the chargeable weight, not just the actual weight. Second, for bulky soft goods, ask whether repacking can shrink the volume. Compressing plush or folding cartons down is sometimes worth doing for air in a way it never is for sea. We cover repacking itself in a separate warehouse post.
What small air shipments cannot carry without checking
Aircraft have stricter cargo rules than ships, and this is where small orders from Yiwu most often stall. Categories that need declaring and checking before anyone books a flight include:
- Anything with a battery in it, including toys, electronics, lights and gadgets with built-in cells.
- Liquids, creams, aerosols and anything under pressure.
- Magnets and products containing strong magnets.
- Powders, even innocent ones.
- Perfumed goods with alcohol content, such as some cosmetics and cleaning products.
None of these are automatically impossible to send. Some travel with the right documentation, some travel on some services and not others, and some genuinely cannot fly. The point is that carriers decide by their own rules, and the way to find out is to declare the product honestly and let the agent check before booking. What you must not do is hide a battery inside a carton of general goods. When it is found, and scanning finds these things, the whole shipment is delayed, and the relationship with the carrier is damaged for everyone. Tell your agent exactly what is in the box, always in detail, and the problem is usually solvable one way or another.
Import charges apply to small shipments too
A short section, but it saves people money and shock. Goods entering your country by air or express go through import formalities like any other freight. Duties, taxes and clearance requirements exist, they differ by country and by product, and the courier or your broker will collect whatever is due at your end. We cannot tell you what your shipment will attract, and you should be suspicious of anyone in China who claims they can. Confirm the position with your own customs broker or authority before you order, especially for a first shipment. Nothing in this post is customs, tax or legal advice.
Choosing between the options for a real order
Here is how the decision usually goes in practice. A few kilos of samples: express, no debate. A small trial order, a few cartons: usually still express, unless the goods are bulky, in which case compare against air freight. A shipment in the low hundreds of kilos: air freight starts to win, and it is worth pricing sea LCL alongside it, because if the goods are not urgent the sea is dramatically cheaper and the comparison focuses the mind. Above that, you are really asking whether the order should wait and travel by sea or rail, which are their own posts.
Season matters too. Air capacity out of China tightens in the weeks before major shopping seasons and before Chinese New Year, and rates move with demand. A shipment that flew cheaply in March can cost noticeably more in November. If your small order is seasonal, book earlier than feels necessary.
What we actually do on the shipping side
For a small order, the Yiwu sourcing and shipping work runs together. The warehouse receives the goods from the supplier, checks and photographs them, weighs and measures every carton, and reports the chargeable weight for each option. You see express against air freight, with the sea number alongside when it is close, and you choose with real figures for that week rather than folklore. Then the goods are packed for the mode chosen, because a carton that survives a sea container and a carton that survives a courier network are not packed identically, and off they go with tracking shared as it happens.
Small orders are how most buyers start with Yiwu, and shipping them well is mostly a matter of honest declarations, accurate dimensions and choosing the tool that fits the weight. Get those three right and air is the least dramatic part of the whole process.
