Why Load Volume Matters in International Shipping
Whether you need to calculate load volume for FCL or LCL shipments to Southeast Asia, getting it right can save you thousands of dollars.
Freight carriers charge based on whichever is greater: actual weight or volumetric weight. Get the volume wrong, and you could be overpaying — or facing unexpected surcharges at the destination port.
Step-by-Step: How to Calculate Load Volume
1. Measure Your Cargo (CBM Method)
The standard unit in ocean freight is CBM (Cubic Meter) . Here’s the formula:
Length (m) × Width (m) × Height (m) = CBM
For example, a pallet measuring 1.2m × 1.0m × 1.5m:
1.2 × 1.0 × 1.5 = 1.8 CBM
If your measurements are in centimeters, divide by 1,000,000:
120cm × 100cm × 150cm ÷ 1,000,000 = 1.8 CBM
2. Calculate Volumetric Weight for Air Freight
Air freight uses a different conversion ratio:
CBM × 167 = Volumetric Weight (kg)
So 1.8 CBM of cargo would have a volumetric weight of:
1.8 × 167 = 300.6 kg
If the actual weight is only 180 kg, the airline will charge you based on 300.6 kg — the volumetric weight.
3. Know Your Container Capacity
For FCL shipments, here’s a quick reference:
表格
| Container Type | Internal Volume (CBM) | Max Payload (kg) |
|---|---|---|
| 20′ GP | ~33 CBM | ~28,000 kg |
| 40′ GP | ~67 CBM | ~28,500 kg |
| 40′ HC | ~76 CBM | ~28,700 kg |
Pro tip: You rarely use 100% of the container’s volume. A realistic loading rate is 85–90% due to packaging shapes and stacking limitations.
4. Don’t Forget the Chargeable Weight Rule
For LCL and air freight, the carrier will compare:
- Actual Gross Weight
- Volumetric Weight
You pay based on whichever is higher.
Common Mistakes Shippers Make
- Ignoring packaging dimensions — Measuring only the product, not the packed box or pallet
- Forgetting stacking gaps — Cargo doesn’t fill every centimeter; leave room for dunnage and air
- Not converting units — Mixing inches and centimeters is a recipe for overcharging
- Assuming FCL is always cheaper — For small volumes, LCL can be more cost-effective

| Cargo Type | Dimensions (cm) | CBM | Volumetric Weight (kg) |
|---|---|---|---|
| Standard Pallet | 120 × 100 × 150 | 1.80 | 300.6 |
| Small Carton | 60 × 40 × 40 | 0.096 | 16.0 |
| Large Carton | 80 × 60 × 80 | 0.384 | 64.1 |
| Drum | 60 × 60 × 90 | 0.324 | 54.1 |

Common Questions About Load Volume Calculation
Do I need to include pallet dimensions? Yes. Always measure the outermost dimensions of your packaged cargo, including pallets. Carriers charge based on the space your shipment actually occupies, not just the product inside.
What if my cargo is irregularly shaped? Use the longest, widest, and tallest points to calculate CBM. Round up to the nearest centimeter to avoid underestimating.
Is CBM the same for air and sea freight? The CBM calculation is the same, but air freight uses a different conversion factor (1 CBM = 167 kg volumetric weight) compared to sea freight (1 CBM = 1,000 kg). This means lightweight but bulky cargo costs much more by air.
