For businesses importing goods from China, logistics planning should begin before the purchase order is finalized.
One of the most common mistakes is confirming the quantity first and calculating the actual shipment volume later. This can result in unexpected logistics costs, inefficient container utilization, additional packaging expenses or even choosing a container that is larger than necessary.
For B2B importers, five factors are particularly important:
CBM, gross weight, packaging dimensions, palletization and container space utilization.
What Is CBM?
CBM means Cubic Meter and is used to measure cargo volume.
For rectangular cartons, the basic calculation is:
Length × Width × Height = CBM
If dimensions are provided in centimeters, they should first be converted into meters.
For example, a carton measuring:
60 × 40 × 50 cm
has a volume of:
0.6 × 0.4 × 0.5 = 0.12 CBM
If you have 100 cartons:
0.12 × 100 = 12 CBM
However, this is the theoretical carton volume. The actual space required inside a container can be different because of palletization, carton shape, stacking limitations and loading efficiency.
Do Not Calculate Only the Product Dimensions
The product itself is not necessarily the final shipping unit.
A product measuring 50 × 30 × 20 cm may be packed in a larger carton with additional protective materials.
The final shipment may include:
- cardboard cartons,
- protective foam,
- wooden frames,
- pallets,
- wrapping,
- additional securing materials.
Therefore, before confirming the order, ask the supplier for the final packed dimensions, not just the product dimensions.
Packaging Dimensions Matter
For a reliable logistics calculation, request:
- carton dimensions,
- carton quantity,
- gross weight,
- product quantity per carton,
- total CBM,
- total gross weight,
- pallet quantity,
- pallet dimensions,
- loading configuration.
This information gives the logistics provider a realistic picture of the shipment before it leaves China.
It can also reveal opportunities to optimize packaging before production is completed.
Sometimes reducing the external carton size by only a few centimeters can improve container utilization significantly.
Weight Is Just as Important as Volume
CBM alone does not determine the most appropriate shipping solution.
Two shipments may occupy the same volume but have completely different weights.
For example, 20 CBM of lightweight foam products and 20 CBM of metal components may require the same approximate volume but have dramatically different weights.
Therefore, logistics planning should always consider:
CBM + Gross Weight
It is also important to distinguish between Net Weight and Gross Weight.
Net Weight refers to the product itself, while Gross Weight includes packaging.
For transportation planning, the gross weight of the final packed shipment is particularly important.
Palletization: Necessary or Additional Cost?
Palletization can make cargo handling, storage and loading much easier.
However, pallets also occupy space.
A shipment that appears to be 20 CBM when calculated based only on cartons may require more physical space after being placed on pallets.
This is why palletization should be discussed before the order is finalized.
Ask:
Does this cargo need to be palletized?
If yes:
What pallet size will be used and how many pallets will there be?
For fragile or sensitive goods, palletization may significantly reduce the risk of damage. For certain cargo types, however, loading without pallets may provide better space utilization if it is safe and operationally appropriate.
Efficient Container Utilization
The goal is not simply to fit the cargo inside a container.
The objective is to use available space efficiently while maintaining cargo safety and complying with loading requirements.
Factors include:
- carton dimensions,
- cargo weight,
- carton shape,
- stacking capability,
- fragile items,
- pallet dimensions,
- loading and unloading requirements.
Different carton sizes can create empty spaces that cannot be effectively filled.
Therefore, the theoretical CBM does not always equal the practical space utilization inside the container.
LCL or FCL?
Not every B2B shipment requires a full container.
For smaller shipments, LCL (Less than Container Load) can be an efficient solution because the cargo shares container space with other shipments.
As shipment volume increases, FCL (Full Container Load) may become more efficient.
This means businesses should not simply ask:
“How many cartons do we have?”
The more important question is:
“What is the total CBM and gross weight, and which shipping solution is most efficient?”
This approach helps businesses avoid paying for unnecessary container capacity while also preventing inefficient shipment splitting.
What Should You Ask Your Chinese Supplier?
Before confirming your order, request a complete packing list containing:
1. Product quantity
Total number of products.
2. Carton quantity
Total number of cartons.
3. Carton dimensions
Length, width and height.
4. Gross weight
Weight per carton and total shipment weight.
5. Total CBM
Total packed volume.
6. Pallet quantity
Number of pallets, if applicable.
7. Pallet dimensions
Length, width and height of each pallet.
8. Loading details
Information about how the cargo will be arranged.
This data can then be reviewed before the order is finalized.
Why Pre-Order Calculation Matters
Transportation cost is part of the product’s landed cost.
If you underestimate the shipment volume, you may also underestimate the final cost of the imported product.
For example, if you expect a shipment to be 25 CBM but the final packed cargo reaches 32 CBM, the difference may have a significant impact on logistics costs and ultimately on your selling price and profit margin.
That is why container planning should happen before confirming the purchase, not after the cargo is already sitting in a warehouse.
A 5-Step Pre-Order Checklist
Before confirming a large order from China:
1. Calculate total CBM.
Multiply the packed unit volume by the number of cartons.
2. Check gross weight.
Do not rely only on the product’s net weight.
3. Confirm final packaging dimensions.
Use carton dimensions rather than product dimensions alone.
4. Determine palletization requirements.
Pallets can affect both volume and loading efficiency.
5. Ask a logistics specialist to review the shipment.
This helps determine whether LCL or FCL is more suitable and how the cargo should be transported.
Efficient international shipping starts before the purchase order is confirmed.
CBM, gross weight, packaging dimensions and palletization are interconnected factors that determine how much space the cargo will actually require.
For B2B importers, calculating these parameters in advance helps control logistics costs, choose the appropriate shipping solution and calculate the final landed cost more accurately.
