Overview

Choosing between sea and air freight impacts your costs, timeline, and cash flow. Here's how to decide.

Sea Freight

Transit time: 15-40 days depending on route

Cost: $3-6 per kg (approximate)

Best for:

  • Large, heavy shipments
  • Non-urgent orders
  • Price-sensitive products
  • Regular inventory replenishment

Options:

  • FCL (Full Container Load) - Rent entire container
  • LCL (Less than Container Load) - Share container space

Air Freight

Transit time: 3-7 days

Cost: $4-8 per kg (approximate)

Best for:

  • Urgent orders
  • High-value, low-weight items
  • Samples and prototypes
  • Seasonal products with tight windows

Breakeven: Air becomes cost-competitive for goods under 100kg or valued over $50/kg.

Decision Framework

Choose Sea When:

  • Order is planned 6-8 weeks ahead
  • Products are heavy or bulky
  • Margins are tight
  • You have existing inventory

Choose Air When:

  • Stock-out situation
  • Product launch deadline
  • High-margin products
  • Small, urgent orders
