CBM & Volumetric Weight FAQ
Why is my air freight chargeable weight higher than my actual weight?
Airlines charge the higher of actual weight and volumetric weight. If your carton is large, the volumetric calculation can exceed your actual kg.
Is CBM the same as weight?
No. CBM is space. Weight is kg. A light but bulky carton can have low kg but high CBM, making it expensive to ship.
Should I use carton dimensions or product dimensions?
Use carton dimensions (the packaged box). Freight pricing is based on the shipped package, not the bare product.
Can this calculator give me exact shipping cost?
No. It gives you CBM and chargeable weight, which are the numbers you need before requesting a freight quote.
