|---|---|---|
| Speed | 3-7 days | 20-45 days |
| Cost | R35-R80/kg | R800-R1,500/CBM (LCL) |
| Best for weight | Under 500 kg | Over 500 kg |

When to Choose Air Freight
- ✅ Urgent shipments — Need it within a week
- ✅ High-value goods — Electronics, pharmaceuticals, samples
- ✅ Perishable items — Fresh agricultural products, flowers
- ✅ Small volumes — Under 2 CBM or 500 kg
- ✅ Time-sensitive industries — Fashion seasons, product launches
- ✅ Replacement parts — Production-critical components
Typical air freight route: King Shaka Airport to destination airport, 3-7 days.
When to Choose Sea Freight
- ✅ Large volumes — Fill a container or multiple CBMs
- ✅ Heavy cargo — Machinery, vehicles, raw materials
- ✅ Cost-sensitive — Budget is the priority over speed
- ✅ Non-urgent — You can plan 4-6 weeks ahead
- ✅ Regular imports — Predictable supply chain
- ✅ Bulk commodities — Mining, agricultural bulk
Typical sea freight route: Durban Port from Shanghai, 25-30 days.
Cost Comparison Example
Shipping 500 kg / 2 CBM from Shanghai to Durban:
| Air Freight | Sea Freight (LCL) | |
|---|---|---|
| Freight cost | ~R25,000 | ~R3,000 |
| Clearance | ~R3,500 | ~R3,500 |
| Local charges | ~R1,500 | ~R2,500 |
| Total | ~R30,000 | ~R9,000 |
| Transit time | 5 days | 28 days |
Air freight costs 3x more but arrives 23 days sooner. The right choice depends on whether the speed justifies the cost for your business.
The Hybrid Approach
Some shipments benefit from combining both:
- Ship bulk inventory by sea freight (4-6 weeks ahead)
- Send urgent top-up stock by air freight
- This balances cost and availability
