Air Freight vs Sea Freight from China: Complete Cost Comparison 2026

When shipping from China, the choice between air freight and sea freight is one of the most important decisions you'll make. Air is faster but significantly more expensive. Sea is cheaper but slower. This guide helps you understand when each mode makes sense based on actual costs, transit times, and business factors.

Air Freight vs Sea Freight: Quick Comparison

Factor	Air Freight	Sea Freight
Transit Time (China to US)	5–7 days	14–28 days (West Coast), 28–35 days (East Coast)
Cost per kg	$3.50–$8.00/kg	$0.50–$1.50/kg
Minimum Charge	Usually 21kg (chargeable weight)	No minimum, but 1 CBM = ~167kg
Maximum Load	Limited by aircraft capacity	Up to 28 tons per 40ft container
Risk of Damage	Lower (less handling)	Higher (more handling, sea conditions)
Ideal For	Urgent, high-value, lightweight goods	High-volume, low-to-medium value goods

Air Freight Costs from China 2026

Air freight rates from China vary by route, carrier, and cargo type:

• China to US West Coast: $3.50–$5.50 per kg
• China to US East Coast: $4.00–$6.50 per kg
• China to Europe (Frankfurt, London): $3.00–$5.00 per kg
• China to Australia: $4.00–$6.00 per kg

Air Freight Surcharges

Air freight quotes typically include:

• AWC (Air Waybill Charge): $30–$50 per shipment
• Fuel Surcharge (AFA): $0.30–$0.80 per kg
• Security Surcharge: $0.10–$0.30 per kg
• Customs Brokerage: $100–$300 per shipment
• Residential/Delivery surcharges: $50–$150 if applicable

Air Freight Chargeable Weight Calculation

Air freight is charged on chargeable weight, which is the higher of:

• Actual weight: Physical weight of the cargo
• Volumetric weight: (L x W x H in cm) / 6000

Example: A shipment weighing 10kg with dimensions 50x40x30cm has volumetric weight of 10kg (50×40×30/6000 = 10), so chargeable weight is 10kg.

Sea Freight Costs from China 2026

Sea freight rates from China vary by container size and route:

• 20ft Container to US West Coast: $2,000–$3,500
• 40ft Container to US West Coast: $3,000–$5,000
• 40ft High Cube to US East Coast: $4,000–$6,500
• 20ft to Rotterdam/Hamburg: $1,500–$2,500
• 40ft to UK (Felixstowe): $2,500–$4,000

Sea Freight Surcharges (All-In Calculation)

Sea freight all-in costs typically include:

• Base Ocean Freight
• BAF (Bunker Adjustment Factor): $100–$400 per 20ft
• PSS (Peak Season Surcharge): $100–$800 during peaks
• CAF (Currency Adjustment Factor): 3–8% of base rate
• Origin THC: $80–$150 per container
• Documentation Fee (DOC): $25–$50

When Air Freight Makes Sense

Pay the premium for air when:

• Time is critical: Product launches, seasonal items, running out of stock
• High-value cargo: Lower insurance costs relative to value
• Lightweight goods: Products with high value-to-weight ratio
• Perishables: Food, pharmaceuticals, temperature-sensitive items
• Sample shipments: Pre-production samples for quality control

Air Freight Break-Even Example

If sea freight costs $0.80/kg and air costs $4.50/kg:

• Air is 5.6x more expensive per kg
• Air saves ~20 days transit time
• Air makes sense if storage/holding costs exceed $0.18/kg/day

When Sea Freight Makes Sense

Choose sea when:

• Volume is high: 500kg+ shipments where air cost is prohibitive
• Product is durable: Can withstand sea conditions and multiple handlings
• Time is flexible: 3–5 weeks lead time is acceptable
• Cost is primary driver: Margins are tight and freight cost matters significantly
• Heavy cargo: Products where air volumetric weight would be very expensive

Sea vs Air: Cost Per Product Example

For a consumer electronics product shipped from Shenzhen to Los Angeles:

Cost Factor	Air Freight	Sea Freight (LCL)	Sea Freight (FCL)
Freight Cost	$1,800 (300kg @ $6/kg)	$600 (10 CBM @ $60/CBM)	$3,200 (40ft container)
Surcharges	$200	$150	$800
Customs	$150	$100	$200
Delivery	$100	$200	$300
Total	$2,250	$1,050	$4,500
Transit Time	5–7 days	18–22 days	14–18 days

Key Takeaways

• Air freight is 5–8x more expensive but 10x faster than sea freight
• Sea freight costs $0.50–$1.50/kg; air freight costs $3.50–$8.00/kg
• Air makes sense for urgent, high-value, or lightweight shipments
• Sea makes sense for high-volume, cost-sensitive goods with flexible timelines
• Consider total landed cost, not just freight cost, when choosing
