Sea Freight vs Air Freight for Amazon FBA
Updated 2026-05-21
Answer: Use sea freight for planned bulk shipments where cost matters, and air freight for launches, urgent replenishment, or high-value lightweight goods where stockout risk is higher than the freight premium.
Direct answer
Sea freight is usually the lower-cost mode for FBA inventory above small-parcel size, while air freight is the practical choice for urgent restocks, launch inventory, and lightweight high-margin goods.
Cost comparison
Ocean LCL is typically priced by CBM, FCL by container, and air freight by chargeable weight. That means bulky products can be surprisingly expensive by air even when actual gross weight is low.
Transit-time tradeoff
Air freight can move door-to-FBA in roughly one to two weeks when documentation is clean. Ocean freight usually needs several weeks after factory pickup, port handling, customs clearance, drayage, and Amazon receiving.
Operating rule
Use ocean for planned inventory and air for cash-flow-protected emergencies. If a stockout will cost more than the air premium, air freight can still be the rational choice.
What still needs human review
- Rates and transit times change by lane, season, carrier, and Amazon receiving conditions.
- Battery, liquid, magnetic, or hazmat cargo requires manual review before mode selection.
