Volumetric & Chargeable Weight Guide
Understand No, Half & Full Volumetric Weight
Your parcel may be light, but a large box can still cost more to ship. International freight considers not only actual weight but also the transport space occupied by the parcel.
Start with These 3 Types of Weight
Actual Weight
The physical weight shown when the fully packed parcel is placed on a scale. If the scale shows 8KG, the actual weight is 8KG.
Volumetric Weight
This reflects how much transport space the parcel occupies. A light but bulky carton may produce a much higher volumetric weight.
Chargeable Weight
This is the final weight used to calculate freight. It may differ depending on the channel's No, Half or Full Volumetric rule.
Two Parcels Can Weigh 8KG but Use Very Different Space
Aircraft, trucks and containers all have limited capacity. A larger carton uses more transport space even when its physical weight is the same.
| Actual Weight | → | Teaching Example Volumetric Weight |
|---|---|---|
| 8 KG | → | 14 KG |
No, Half & Full Volumetric Explained
Actual weight may apply when conditions are met
Some channels may charge by actual weight when the parcel qualifies for that channel's volumetric allowance.
| Actual Weight | 8KG |
| Teaching Example Volumetric Weight | 14KG |
| Teaching result | 8KG |
No Volumetric does not mean volume is ignored without limit. Weight, dimensions, goods type and other conditions may still apply.
Only part of the extra volumetric weight is charged
For this teaching example, assume the channel charges half of the difference.
| Actual Weight | 8KG |
| Teaching Example Volumetric Weight | 14KG |
| Difference | 6KG |
| Half the difference | 3KG |
| Teaching result | 11KG |
This is a teaching example only. Actual Half Volumetric formulas may differ by route and shipping channel.
The full volumetric rule is applied
For this example, assume the channel uses the higher of actual and volumetric weight.
| Actual Weight | 8KG |
| Teaching Example Volumetric Weight | 14KG |
| Teaching result | 14KG |
Actual formulas, minimum charging and rounding rules still depend on the selected shipping channel.
The Same Parcel Can Produce Very Different Chargeable Weights
| Item | Teaching Example |
|---|---|
| Actual Weight | 8 KG |
| Teaching Example Volumetric Weight | 14 KG |
| No Volumetric Example | 8 KG |
| Half Volumetric Example | 11 KG |
| Full Volumetric Example | 14 KG |
What Does 1 m³ Mean?
m³ means cubic metre and describes the physical space occupied by cargo.
1m × 1m × 1m = 1m³
Length × Width × Height
For example, a packed item measuring 0.5m × 0.5m × 0.4m has a volume of 0.1m³.
How Can You Reduce Unnecessary Volumetric Weight?
Avoid oversized cartons
A carton much larger than the goods creates unnecessary space.
Reduce unnecessary empty space
Keep required protection but avoid excessive unused space.
Compress suitable soft goods
Clothing and other compressible items may require less space.
Measure final packed dimensions
Use the dimensions of the completed package, not only the product.
Select Your Shipping Route
The examples above explain the concept. For an actual shipment, check the selected route for current rates, volumetric formulas and applicable allowances.
Common Questions from First-Time Shippers
My parcel weighs only 5KG. Will I definitely be charged for 5KG?
Does a larger box mean higher volumetric weight?
Does No Volumetric mean volume is completely ignored?
Why do different logistics companies calculate different weights?
Does Half Volumetric always mean dividing by two?
How do I know my actual chargeable weight?
