A framework for deciding between ocean and air based on cost per kg, timelines and cash flow.
Choosing between sea and air freight is a trade-off between cost, speed and cash flow. The right answer depends on your margins, timelines and product weight-to-value ratio.
When sea freight wins
Ocean is dramatically cheaper per kilogram and the default for bulky, heavy or non-urgent goods. The cost is time — expect several weeks of transit plus port handling.
When air freight wins
- Time-sensitive launches or restocks that can't wait.
- High-value, low-weight products where freight is a small share of cost.
- Small first orders where speed of learning matters more than margin.
A simple decision rule
Compare freight as a percentage of landed cost. If air adds only a few percent to a high-value item, the speed is often worth it. For low-value bulk goods, air can cost more than the product itself — sea is the clear choice.
Frequently asked questions
- Is air or sea freight cheaper?
- Sea freight is far cheaper per kilogram and best for heavy or bulky goods. Air freight costs more but is worth it for urgent, high-value, low-weight products where speed matters and freight is a small share of landed cost.
- How much faster is air freight than sea?
- Air freight typically delivers in a few days versus several weeks for ocean freight, though the exact gap depends on route, customs clearance and inland transport at both ends.
