Cost Comparison: Which Option Saves More Money?
Understanding the cost structures of both shipping methods helps maximize profits:
💰 Air Freight Pricing Structure
✅ Charged by weight and volumetric dimensions.
✅ Higher base rates + additional fees for fuel, security, and handling.
✅ Peak seasons (holidays) result in premium rates.
💰 Sea Freight Pricing Structure
✅ Charged by container size (LCL vs. FCL).
✅ Lower base rates + charges for customs, documentation, and handling.
✅ Seasonal fluctuations impact rates, but still cheaper than air.
📌 Example Cost Analysis
| Shipment Size | Air Freight Cost | Sea Freight Cost | Potential Savings |
| 200 kg | $1,200 | $600 | $600 (Sea) |
| 500 kg | $2,500 | $1,000 | $1,500 (Sea) |
| 1,000 kg | $5,000 | $1,800 | $3,200 (Sea) |
🚀 Key Takeaway: Sea freight can save you thousands on bulk shipments, but air freight is worth the cost for urgent, high-margin products.
