The Core Trade-Off: Speed vs Cost
The choice between air and sea freight almost always comes down to balancing urgency against budget. But there are several other factors worth considering.
Air Freight Advantages
- Speed: Typical transit from China to Kenya is 4-8 days vs 25-35 days by sea
- Security: Lower risk of damage and theft
- Predictability: Multiple flights daily, less weather disruption
- No sea cargoes: Suitable for perishables, electronics, fashion
Air Freight Disadvantages
- Significantly higher cost per kg (typically 4-6x sea freight)
- Size and weight restrictions
- Higher carbon footprint
Sea Freight Advantages
- Cost: Much cheaper for large volumes
- Capacity: No practical size or weight limits
- Heavy goods: Machinery, vehicles, bulk commodities
When to Choose Air Freight
High-value items, time-sensitive products, perishables, small shipments where the extra cost is justified by faster inventory turns, and situations where capital tied up in transit is expensive.
When to Choose Sea Freight
Bulk commodities, heavy machinery, furniture, raw materials, non-perishable consumer goods with longer lead times, and any cargo where volume makes air freight prohibitively expensive.
