For Amazon sellers, few moments are as frustrating as seeing hard-earned profits evaporate due to unexpectedly high shipping costs. The complexity of FBA (Fulfillment by Amazon) freight charges often catches sellers unprepared. This article examines the structure of FBA shipping costs, compares different transportation methods, and provides practical strategies for cost control.
I. How FBA Shipping Costs Are Calculated: The Dual Weight System
FBA shipping costs aren't based solely on either physical weight or volume—they use a hybrid calculation that considers both and charges whichever is greater. This system ensures carriers cover their operational expenses fairly.
Key Weight Measurements:
- Actual Weight: The physical mass of your package measured in kilograms (kg).
- Volumetric Weight (Dimensional Weight): Calculated to account for lightweight but bulky items (like bedding or furniture) that occupy disproportionate space. The formula is:
Volumetric Weight (kg) = Length (cm) × Width (cm) × Height (cm) ÷ Divisor
The divisor varies by shipping method and carrier—typically 5000 for express shipping and 6000 for sea/air freight.
Example: A 50×40×30 cm box with a 6000 divisor has a volumetric weight of 10 kg. If its actual weight is 8 kg, you'll pay for 10 kg; if it weighs 12 kg, you'll pay for 12 kg.

These price ranges are estimates—actual costs fluctuate based on fuel prices, seasonality, and market demand. Always obtain multiple quotes.
1. Ocean Freight: Cost-Effective for Large Shipments
Ideal for bulk goods with flexible timelines, ocean shipping offers two primary options:
-
LCL (Less than Container Load):
Priced per cubic meter (CBM ≈ 167 kg at 6000 divisor). Current rates:
- Express Ships (e.g., Matson, ZIM): 15-25 days transit at $2.10-$3.50/kg ($350-$580/CBM)
- Standard Ships (e.g., Evergreen, COSCO): 30-40 days transit at $1.10-$2.10/kg ($180-$350/CBM)
- FCL (Full Container Load): Priced per container (20GP/40GP/40HQ). Current West Coast U.S. rates: $800-$1500/container (excluding destination fees). Best for shipments exceeding 10 CBM.
2. Air Freight: Balanced Speed and Cost
Suited for medium-sized shipments or inventory replenishment:
-
Air Express (with last-mile delivery):
10-20 days to U.S. coasts. Rates:
- Small shipments (<100 kg): $7-$10/kg
- Medium (100-500 kg): $5-$7/kg
- Large (>500 kg): $4.20-$5.60/kg
- Commercial Courier (DHL/FedEx/UPS): 3-5 days delivery at $8.40-$16.80/kg (5000 divisor). Remote areas may incur 30%-50% surcharges.
III. Additional Cost Considerations
Beyond base shipping, these expenses impact total logistics costs:
- Customs Clearance: $42-$112 per shipment (sometimes included)
- Import Duties: Typically 3%-8% of declared value (varies by HS code)
- Surcharges: Fuel adjustments (10%-20%), remote delivery fees ($0.42-$0.70/kg), oversized item fees
IV. Essential Questions for Freight Forwarders
When obtaining quotes, clarify these critical details:
- Is volumetric weight included? Which divisor (5000 or 6000) applies?
- Does the quote cover door-to-door delivery and customs clearance? Are duties included?
- What are the delivery guarantees? What compensation applies for delays?
- What clearance methods are used? Will you receive shipping documents and tracking?
V. Strategic Recommendations
FBA shipping costs hinge on comparing actual and volumetric weights, charging whichever is higher. Key pricing ranges:
- Ocean: $1.10-$3.50/kg (15-40 days)
- Air: $4.20-$10/kg (10-20 days)
- Courier: $8.40-$16.80/kg (3-5 days)
Optimal shipping strategies:
- Low-density items: Prioritize ocean freight
- Emergency replenishment: Use courier services
- Regular restocking: Air express or express ocean
- Bulk shipments: Full container loads
Always compare multiple quotes and prioritize carriers with Amazon's SPN certification for reliability.
