What Goes Into a China Shipping Cost?
Shipping cost from China has three layers: (1) freight — the airline, ocean line, or courier rate; (2) origin & destination charges — inland trucking, terminal handling (THC), customs clearance, and documentation; (3) duties & taxes — import duty (0%–25%), VAT/GST (0%–20%). A quoted "$5/kg air" or "$80/CBM sea" rarely includes THC, duty, or last-mile — that's why a DDP all-in quote is the only number you should compare. Below are the formulas for each mode, with real 2026 rates.
Shipping Cost Formulas by Mode
| Mode | Formula | Unit | 2026 China→US Rate |
|---|---|---|---|
| Air freight | $/kg × max(actual, L×W×H÷6000) | $/kg | $4 – $9/kg |
| Sea LCL | $/CBM × CBM (min 1 CBM) | $/CBM | $60 – $120/CBM |
| Sea FCL | Flat per 20ft / 40ft container | $/container | $1,200 – $3,500 |
| Express (DHL/FedEx) | $/kg × max(actual, L×W×H÷5000) | $/kg | $8 – $14/kg |
| Rail (China→EU) | $/CBM × CBM | $/CBM | $90 – $160/CBM |
Air Freight: Chargeable Weight Worked Example
Air carriers charge on chargeable weight — the greater of actual weight or volumetric weight. This is the #1 surprise for first-time shippers of bulky, light goods.
Volumetric weight (air, IATA): (L × W × H in cm) ÷ 6000
Volumetric weight (express): (L × W × H in cm) ÷ 5000
Example: A carton of plush toys measures 60 × 50 × 40 cm and weighs 8 kg.
- Volumetric weight (air) = (60 × 50 × 40) ÷ 6000 = 20 kg
- Actual weight = 8 kg
- Chargeable weight = max(20, 8) = 20 kg
- At $6/kg air to US → $120 freight on an 8 kg box
Express courier (÷5000) would charge 24 kg — even more. This is why bulky low-density goods should go sea LCL, not air.
Sea LCL & FCL: CBM and Container Rates
Sea freight is priced by CBM (cubic meter) for LCL (less-than-container-load) and by container for FCL (full-container-load).
- CBM formula: (L × W × H in cm) ÷ 1,000,000, or L × W × H in meters.
- LCL minimum: most routes charge a 1 CBM minimum even if your cargo is 0.3 CBM.
- FCL break-even: LCL becomes more expensive than FCL around 15 CBM (20ft) or 30 CBM (40ft). Above that, book a full container.
- 2026 FCL rates (China→US West Coast): 20ft $1,200–$2,000, 40ft $2,000–$3,500 (all-in ocean + terminal, excludes duty).
Add-On Charges (Often Hidden in FOB Quotes)
| Charge | Range | Notes |
|---|---|---|
| China inland trucking (factory → port) | $80 – $500 | Yiwu→Ningbo ~$120; Shenzhen→Yantian ~$80 |
| THC (terminal handling) | $30 – $80/CBM (sea); $0.20 – $0.40/kg (air) | Port/airport terminal fee |
| Export customs clearance | $40 – $150 | Brokers fee + declaration |
| Documentation (BL, CO, FORM A/E) | $15 – $60 | Per document |
| Import customs clearance (destination) | $50 – $200 | Broker fee |
| Import duty | 0% – 25% of value | By HS code; Section 301 for China |
| VAT / GST | 0% – 20% | By destination country |
| Last-mile delivery | $0.50 – $3/unit | Port to warehouse / FBA |
DDP quotes bundle all of these into one rate; FOB quotes hide THC, docs, import clearance, and duty. Always convert FOB to landed cost before comparing.
Worked Example: 500 kg / 2 CBM to the US
Shipment of 500 kg / 2 CBM of kitchenware from Ningbo to Los Angeles.
Option A — Air freight (DDP):
- Chargeable weight = max(500 kg, 2 CBM equivalent). Air volumetric = 2,000,000 cm³ ÷ 6000 = 333 kg → chargeable = 500 kg
- Air DDP: $5.50/kg × 500 = $2,750 (all-in, duty included)
- Transit: 5–8 days door-to-door
Option B — Sea LCL (DDP):
- CBM = 2.0 (above 1 CBM min)
- Sea LCL DDP: $80/CBM × 2 = $160 (all-in, duty included)
- Transit: 25–35 days door-to-door
Air is 17× more expensive but 5× faster. For a $10/unit product with 30-day sea lead time, the $2,590 premium buys 25 days of working capital and avoids a stockout — worth it for trending or high-margin goods.
Online Freight Calculators vs Real Quotes
- Freightos — instant air/sea quotes from a forwarder marketplace; good for ballpark but misses THC and duty.
- Alibaba Logistics — integrated with 1688/Alibaba orders; convenient for small parcels.

Frequently Asked Questions
1. How do I calculate shipping cost from China?
Pick the mode and apply its formula: air = $/kg × chargeable weight (max of actual or L×W×H÷6000); sea LCL = $/CBM × CBM (min 1 CBM); sea FCL = flat per container; express = $/kg × L×W×H÷5000; rail = $/CBM × CBM. Add inland trucking ($80–$500), THC, customs ($40–$150 export, $50–$200 import), duty, VAT, and last-mile.
2. What is the air freight chargeable weight formula?
Chargeable weight = max(actual gross weight, volumetric weight), where volumetric weight = (L × W × H in cm) ÷ 6000 for IATA air. A 60×50×40 cm box weighing 8 kg is charged at 20 kg. Express courier uses ÷5000 (24 kg). Always ask for both numbers before booking.
3. How is sea freight LCL cost calculated?
Sea LCL = $/CBM × CBM, where CBM = (L × W × H in cm) ÷ 1,000,000. The minimum chargeable CBM is 1.0. 2026 China→US LCL DDP rates: $60–$120/CBM. FCL is a flat per-container rate ($1,200–$3,500) regardless of CBM; switch from LCL to FCL around 15 CBM.
4. What is the difference between DDP and FOB shipping cost?
FOB covers goods loaded onto the China vessel; you pay freight, insurance, import duty, and delivery separately. DDP is all-in: freight, insurance, duty, and last-mile to your door. DDP costs 5%–15% more but removes admin and duty surprises — always compare landed cost, not just freight.
5. How much does it cost to ship 500 kg / 2 CBM from China to the US?
Air: $5.50/kg × 500 = $2,750 (DDP, 5–8 days). Sea LCL: $80/CBM × 2 = $160 (DDP, 25–35 days). Air is 17× more expensive but 5× faster. Use air for high-value, urgent, or trending stock; sea for bulk low-value goods.
6. Are there online shipping calculators for China freight?
Yes — Freightos (air/sea instant quotes), Alibaba Logistics, and 17track (tracking). But none include Section 301 duty, THC, or peak surcharges. Always get 2–3 all-in DDP forwarder quotes before booking. Yeatru quotes DDP within 24 hours with every line item shown.
Common Pitfalls to Avoid
- Accepting a flat DDP rate without line items. A real DDP quote breaks out freight, duty, VAT, clearance, and last-mile. A single per-kg number hides costs that surface as surprise invoices or low-quality service.
- Choosing CIF for control of freight. Under CIF the supplier picks the carrier and inflates freight by 15–25%. Choose FOB (you control the line) or DDP (all-in, your forwarder) — never CIF unless you have no other option.
- No transit-time buffer for FBA restocks. Sea freight from China runs 25–40 days + 5–7 days FBA receiving. Order 45–60 days before you need stock in FBA, not 30. Running out of stock kills your Amazon ranking.
- Ignoring ISPM-15 for wooden pallets. EU and US customs require heat-treated pallets with the IPPC stamp. Missing stamps = container detained, €400–$600 fumigation, 3–7 day delay.
- No cargo insurance. Freight forwarders' liability is limited to ~$2/kg by convention. For high-value cargo, buy separate all-risks insurance (0.3–0.5% of value) — it costs $50 and pays out $10,000.
Conclusion
Calculating China shipping cost comes down to the right formula per mode (air chargeable weight, sea CBM, FCL flat) plus the often-hidden add-ons: THC, customs clearance, duty, and last-mile. The cheapest-looking rate is rarely the cheapest landed cost — convert FOB to DDP-equivalent before deciding. For 500 kg/2 CBM, sea LCL at $160 beats air's $2,750 unless the 25-day time savings is worth the premium. Send Yeatru your carton dimensions and weight — we'll calculate air, sea, express, and rail all-in DDP costs side-by-side within 24 hours.
