Key takeaways
- Start with the required delivery date and final packed cargo data.
- Air charges by chargeable weight; ocean planning depends strongly on CBM and container fit.
- Compare the complete pickup-to-delivery scope, not only the main freight line.
Scope note: This article provides general planning guidance. Carrier acceptance, customs, compliance, price and timing must be confirmed for the actual shipment.
Start with the business constraint
Air freight and sea freight solve different operational problems. The useful comparison begins with the required arrival date, inventory consequence and verified cargo profile—not a general claim that one mode is better.
- Use air when delay has a high business cost and the cargo is suitable.
- Use sea when volume is larger and the schedule allows consolidation and sailing time.
- Consider a split shipment when a small urgent quantity can protect operations while the balance moves by sea.
Compare how each mode charges
Airlines compare actual weight and volumetric weight and normally charge the higher figure. Ocean LCL commonly uses volume or revenue-ton rules, while FCL depends on container type, lane and equipment.
- Measure every package after export packing.
- Include origin, destination, customs and delivery charges in the comparison.
- Do not compare an airport rate with a door-delivery ocean quote.
Review handling and acceptance
Cargo condition can change the available choices. Batteries, magnetic goods, oversized pieces, fragile products and inadequate packing require additional review.
- Confirm carrier acceptance before promising a schedule.
- Allow for pickup, export handling, customs release and final delivery.
- Treat transit guidance as conditional until the shipment is booked.
