Sea Freight: The Cost-Effective Standard
Key Insight: Sea freight vs air freight for underwear imports: sea costs $0.05-0.15 per pair (25-35 days to Europe, 15-20 days to US West Coast, 30-45 days to South America), while air costs $0.50-1.50 per pair (3-7 days anywhere). The optimal strategy ships 80% by sea for planned inventory (booking 4-6 weeks ahead secures best rates) and air-freights 20% for emergency stock replenishment or seasonal peak demand. Air freight should only be used for high-margin products ($15+ retail) where stockout costs exceed freight premium. Logistics guide →

Frequently Asked Questions
Q: When should I absolutely use air freight?
A: Three scenarios: (1) you missed a seasonal deadline and stockout costs exceed air freight premium, (2) you’re launching a new product and need samples for a trade show in 2 weeks, or (3) your sea shipment is delayed and you need 500 units to bridge the gap. Rule of thumb: if the product retails above $15, air freight the emergency units.
Q: How far in advance should I book sea freight?
A: Book 4-6 weeks before desired departure date. Rates can fluctuate 30-50% within a single month. Booking early secures both the best rate and guaranteed space — during peak season (August-October), unbooked containers can wait 2-3 weeks for vessel space.
