Air is not “faster sea”. It is another economy. Sea is not “cheap air”. It is another time scale. For import from China into Serbia most firms need a mix of modes: sea for bulk, air for samples and holes in stock.
One table
| Factor | Sea (FCL / LCL) | Air |
|---|---|---|
| Cost per kg or CBM | Lower | Higher, often several times |
| Transit | Weeks | Days to about 2 weeks door-ish |
| Predictability | Seasonal shocks | Capacity and rates swing |
| Fits | Volume, heavy, cheap | Urgent, light, high value |
| Handling | More touches (especially LCL) | Fewer, stricter security |
Routes and last mile: Transport China-Serbia.
When to pick sea
- Stable demand and a buying plan 8–12+ weeks ahead.
- Low value per kg / high CBM.
- Seasonal stock before a sales peak.
- Tool or mould and first larger series where the date allows.
FCL or LCL is a decision inside sea: FCL or LCL.
When to pick air
- Samples and a signed gold sample: faster loops with the factory.
- Launch or promo: late sea means a missed date.
- Stock-out: lost-sale margin is bigger than the freight gap.
- High value, low weight (electronics, parts).
- Critical spare for a line in Serbia.
If you fly everything, landed cost punishes the catalogue.
A mix that works
Trader example:
- 80–90% of volume by sea (monthly FCL or consolidated LCL),
- 10–20% air buffer for bestsellers,
- samples always air or courier.
Production example:
- materials and components by sea,
- urgent inserts by air,
- first pilot lot by air until QC holds.
Simple decision math
Compute cost of being late:
- Lost sales / buyer penalty / line stop = L
- Air minus sea freight = D
If L is greater than D, air is the cheaper business choice, even when freight is higher.
Put both scenarios into landed cost.
Chargeable weight trap
Air is often billed on chargeable weight (the higher of actual and volumetric). Light bulky goods can shock the quote. Ask for a rate on carton dimensions, not “about 200 kg”.
Risks by mode
Sea: port delay, demurrage, moisture, LCL damage, documents. Air: rate spikes, embargo or capacity, stricter lithium and battery rules, airport peak at customs.
QC and packing still apply: QC check list.
Documents and FTA
The mode does not remove the need for a correct invoice and origin proof if you want preference. The FTA is in force from 1 July 2024: FTA. Air can arrive before the COO if you are slow with papers. Run both in parallel.
Chinese New Year
Before Chinese New Year plants close and freight jumps. Firms that plan:
- finish sea ships earlier,
- keep an air budget for after-CNY holes,
- do not expect a “normal” production lead in February.
Check list before you pick
- Date in warehouse or at the buyer
- CBM, GW, carton sizes
- Value per kg
- Hazard (batteries, magnets, powder)
- Whether a split 70% sea plus 30% air is possible
- QC status
Process: Import process.
Split shipment in practice
Example: 1,200 kg / 12 CBM of urgent range.
- 200 kg of bestsellers by air (covers about 10 days of sales),
- the rest by sea FCL or LCL.
Fly only the part that must fly. A split needs two document trees and two customs flows. Count broker time. It is still often cheaper than all-air or a stock-out.
When not to fly
- Low value per kg (cheap plastic, bulky décor),
- goods that can wait 6 weeks without lost sales,
- undefined QC (do not fly a problem home faster),
- lithium or hazard without papers ready.
Tell the factory: air shipment, max carton weight, labels, no unmarked wood. Plants used to sea often pack too heavy or with banned material.
For a comparable air or sea quote (and a split), send dimensions, weight and date to contact. You get clear options for this order.
