Choose transport using total business impact, not freight price alone. The cheapest mode can be expensive if it causes a stockout, while the fastest mode can destroy margin on bulky low-value goods.
Courier
Express couriers are convenient for samples, documents, and smaller parcels. Door-to-door tracking and simplified coordination can justify the premium. Confirm dimensional-weight pricing, prohibited goods, remote-area charges, duties, and who acts in customs clearance.
Air freight
Air cargo suits higher-value, time-sensitive, lighter, or more compact shipments that are too large for economical courier service. Costs commonly depend on chargeable weight, routing, security, fuel, terminal handling, and pickup and delivery at both ends.
Sea freight
Ocean freight is often used for larger, heavier, and less time-sensitive goods. Compare full-container and less-than-container options using total origin, destination, handling, documentation, demurrage, detention, and final-delivery costs—not only the ocean line item.
Build a routing decision
Get current quotes for the same shipment details and Incoterms basis. Include packed dimensions and weight, commodity, hazardous status, addresses, ready date, required delivery date, and insurance needs.
- Use courier or air for samples, launch inventory, or stockout prevention when margin supports it.
- Use ocean for planned replenishment with enough buffer and stable demand.
- Consider splitting a shipment when a small urgent quantity protects revenue while the balance travels economically.
Frequently asked questions
Is sea freight always cheaper than air freight?
No. For small shipments, minimum charges and origin/destination fees can make courier or air competitive. Compare door-to-door totals for the actual packed weight and dimensions.
