Air freight from China is the fastest way to move your goods, but it's also the most expensive. The question that stumps every importer is simple: when does air freight actually justify its cost compared to sea freight? In this guide from MESAMA, we help you make the right call between air and sea freight.
✈️ Before you decide, calculate the chargeable weight of your shipment with our free volumetric weight calculator, and check its sea volume with the CBM calculator.
Air vs. Sea Freight: A Quick Comparison
| Criteria | Air Freight | Sea Freight |
|---|---|---|
| Speed | 3 – 7 days | 25 – 40 days |
| Cost | High | Low |
| Best for | Urgent / light / high-value goods | Large / heavy volumes |
| Pricing method | Weight or volumetric weight | Volume (CBM), usually |
When Is Air Freight Worth It?
Choose air freight when:
- Your goods are urgent (stockout, peak selling season).
- They're light and high-value (electronics, precision parts).
- The quantity is small, so the cost difference is manageable.
- You need to test a product quickly before placing a large order by sea.
When Is It Not Worth It?
Avoid air freight when your goods are heavy, bulky, or low-value, because the shipping cost can wipe out your profit margin. In those cases, sea freight is the economical choice.
Volumetric Weight: The Concept That Matters Most
With air freight, the cost is based on the greater of two figures: actual weight and volumetric weight. Volumetric weight is calculated roughly as (length × width × height in cm) ÷ 6,000. So light, bulky goods are often priced by their volume rather than their weight. Use the CBM calculator to estimate your shipment's dimensions.
Types of Air Freight
- Direct air freight: the fastest and most expensive.
- Consolidated air freight: combining shipments to lower the cost.
- Express shipping: for samples and very small orders sent via express courier companies.
MESAMA's Advice
The decision isn't always "air or sea" — sometimes the smart move is a mix: ship a sample or an urgent batch by air, and send the main quantity by sea.
