Volumetric weight in three steps
- 1. Measure your carton in cm (L × W × H) and multiply — that's cubic centimeters per carton.
- 2. Divide by the mode's divisor: air 6000, express 5000 (per carton, then × quantity). For sea, divide by 1,000,000 to get CBM.
- 3. Compare with actual weight — the carrier charges whichever is higher. That number is your chargeable weight.
| Mode | Formula | Billed in | Divisor |
|---|---|---|---|
| Air freight | L×W×H (cm) × qty | kg | ÷ 6,000 |
| Express (DHL/FedEx/UPS) | L×W×H (cm) × qty | kg | ÷ 5,000 |
| Sea LCL | L×W×H (cm) × qty | CBM (m³) | ÷ 1,000,000 |

+Which is cheaper, air or sea?
By weight, air runs $3.5–8/kg from China; sea LCL runs roughly $45–90 per CBM. Below ~300 kg or in a hurry, air wins; above 2 CBM, sea almost always wins. Between 10–15 CBM, ask us to quote both LCL and a full container.
+Why is express divided by 5000 but air by 6000?
Express networks pack denser planes and apply a stricter divisor — they charge for space more aggressively. Same carton costs ~17% more as express chargeable weight than air.
+How do I lower my volumetric weight?
Smaller cartons, denser packing, compressible goods vacuum-packed. Our warehouse repacks and consolidates multiple suppliers to squeeze every CBM — included free for 30 days.
