What is CBM in Containers?<\/b><\/h2>\n
Illustration of a cube-shaped item with 1 CBM<\/figcaption><\/figure>\n To reiterate the whole question, let’s get back to “What is CBM in containers?”<\/p>\n
CBM is the abbreviation of Cubic Meter. In international shipping, it\u2019s used to calculate how much space your cargo takes up inside a container. One CBM equals the volume of a cube that\u2019s 1 meter in length, width, and height.<\/p>\n
To give you an example of how CBM works, it goes by the following illustrations:<\/p>\n
\n
- A simple box (with dimensions similar to the image above) equals 1 CBM.<\/li>\n
- A smaller package, say 0.5m x 0.5m x 0.5m, equals 0.125 CBM.<\/li>\n<\/ul>\n
CBM becomes especially important when you\u2019re shipping goods by LCL (Less than Container Load), where your cargo shares space in a container with other shipments.<\/p>\n
It also comes into play when calculating rates for FCL (Full Container Load) to ensure you’re maximizing space.<\/p>\n
Importance of Knowing the CBM of Each Container<\/b><\/h2>\n
CBM plays a huge role in determining your shipping costs – sometimes even more than weight. Here\u2019s why:<\/p>\n
Freight Rates<\/strong><\/h3>\n
Most sea freight (and even some air and rail freight) charges are based on either the CBM or the weight of your cargo, whichever is greater.<\/p>\n
As such, this is called \u201cchargeable weight.\u201d For bulky but lightweight items, you\u2019ll pay based on CBM; for heavy, compact items, weight might be the main factor.<\/span><\/p>\n
Container Limits<\/strong><\/h3>\n
Shipping containers have both weight and volume limits. If your goods are lightweight but take up a lot of space, you might fill up the container\u2019s CBM before reaching its weight limit, and vice versa.<\/p>\n
Logistics Planning<\/strong><\/h3>\n
If you have higher CBM, it means you must spend more costs into the shipment process and space to keep up with the cargo’s overall volume.<\/p>\n
Optimizing your shipment\u2019s CBM can lead to significant cost savings and more efficient logistics.<\/p>\n
Impact of CBM on Shipping Costs<\/b><\/h2>\n
How CBM impacts shipping costs<\/figcaption><\/figure>\n Freight charges are based on either volume (CBM) or actual weight, whichever is higher. This is called the chargeable weight, which a shipping company can take into account since\u00a0a container can either get full from:<\/p>\n
\n
- Too many heavy items (reaching the weight limit), or<\/span><\/li>\n
- Too many bulky items (reaching the volume limit)<\/span><\/li>\n<\/ul>\n
Let\u2019s say you have two shipments:<\/span><\/p>\n
\n
- Shipment A<\/b>: 0.8 CBM, 1,200 kg<\/span><\/li>\n
- Shipment B<\/b>: 1.6 CBM, 400 kg<\/span><\/li>\n<\/ul>\n
Shipment A will be charged by weight. Shipment B, although lighter, takes up more space and is charged by volume (CBM).<\/span><\/p>\n
In sea freight, this calculation is usually:<\/p>\n
\n
- 1 CBM = 1 metric ton (1,000 kg)<\/b><\/li>\n<\/ul>\n
In <\/span>air freight<\/b>, it\u2019s:<\/span><\/p>\n
\n
- 1 CBM = 167 kg volumetric weight<\/b><\/li>\n<\/ul>\n
That means even if your cargo is feather-light, like pillows, if it takes up 10 CBM, your charges will reflect that large volume.<\/span><\/p>\n
CBM Conversion to KG<\/b><\/h2>\n
If you’re trying to compare shipping charges by volume and weight, it helps to know how CBM translates to kilograms.<\/span><\/p>\n
Sea Freight:<\/b><\/h3>\n
\n
- Standard chargeable weight: <\/span>1 CBM = 1,000 kg<\/li>\n
- If your cargo is over 1,000 kg per CBM, it will be charged by weight.<\/li>\n
- If under, you pay by CBM.<\/li>\n<\/ul>\n
Air Freight:<\/b><\/h3>\n
\n
- Chargeable weight: <\/span>1 CBM = 167 kg<\/li>\n
- Formula: <\/span>(Length x Width x Height in cm) \/ 6,000 = chargeable weight in kg<\/span><\/li>\n<\/ul>\n
Even if you\u2019re not shipping by air, this gives you insight into how much space matters versus physical weight.<\/span><\/p>\n
How to Calculate the CBM of Different Package Sizes<\/b><\/h2>\n
To find the CBM of any package, use this simple formula:<\/span><\/p>\n
CBM = Length (m) \u00d7 Width (m) \u00d7 Height (m)<\/strong><\/em><\/p><\/blockquote>\n
Here are a few quick examples:<\/span><\/p>\n
A Single Box<\/b><\/h3>\n
\n
- Dimensions: 1.0m x 0.8m x 0.6m<\/span><\/li>\n
- CBM = 1.0 \u00d7 0.8 \u00d7 0.6 = <\/span>0.48 CBM<\/li>\n<\/ul>\n
Multiple Boxes<\/b><\/h3>\n
\n
- Box dimensions: 0.5m x 0.4m x 0.3m<\/span><\/li>\n
- 20 boxes<\/span><\/li>\n
- One box = 0.5 \u00d7 0.4 \u00d7 0.3 = 0.06 CBM<\/span><\/li>\n
- Total CBM = 0.06 \u00d7 20 = <\/span>1.2 CBM<\/li>\n<\/ul>\n
In Centimeters<\/b><\/h3>\n
If your dimensions are in cm, convert to meters first. Then, divide each number by 100.<\/span><\/p>\n
\n
- Dimensions: 80cm x 60cm x 50cm = 0.8m x 0.6m x 0.5m<\/span><\/li>\n
- CBM = 0.8 \u00d7 0.6 \u00d7 0.5 = <\/span>0.24 CBM<\/li>\n<\/ul>\n
Calculating Sea Shipment Cost with CBM<\/b><\/h2>\n
Once you\u2019ve calculated CBM, estimating shipping cost becomes much easier. <\/span>Here\u2019s the basic formula: <\/span><\/p>\n
Total Freight Cost = CBM x Rate per CBM<\/b><\/em><\/p><\/blockquote>\n
Let\u2019s say the freight rate is $75 per CBM, and you\u2019re shipping 3.6 CBM of goods. By calculating these numbers, the following is the final shipping cost:<\/span><\/p>\n
3.6 CBM x $75 = $270 shipping cost<\/strong><\/p>\n
But remember, this is usually just the <\/span>base ocean freight charge. Other charges may include:<\/span><\/p>\n
\n
- Origin port charges<\/span><\/li>\n
- Destination handling fee<\/span><\/li>\n
- Customs clearance<\/span><\/li>\n
- Delivery to the final address<\/span><\/li>\n<\/ul>\n
Still, CBM is the foundation of it all, meaning that you should ensure your budget can cover the charge before and after possible cost changes.<\/span><\/p>\n
CBM for Different Container Sizes<\/b><\/h2>\n
Different shipping containers have different maximum CBM capacities. Check the following table to see the difference in CBM in each container size:<\/p>\n
\n\n\n
\n \nContainer Type<\/th>\n Internal Dimensions (m)<\/th>\n Max CBM (approx.)<\/th>\n<\/tr>\n<\/thead>\n \n 20\u2019 Standard<\/strong><\/td>\n 6 x 2.4 x 2.6<\/td>\n 33<\/td>\n<\/tr>\n \n 40\u2019 Standard<\/strong><\/td>\n 12 x 2.4 x 2.6<\/td>\n 67<\/td>\n<\/tr>\n \n 40\u2019 High Cube<\/strong><\/td>\n 12 x 2.4 x 2.9<\/td>\n 76<\/td>\n<\/tr>\n \n 45\u2019 High Cube<\/strong><\/td>\n 13.5 x 2.4 x 2.9<\/td>\n 86<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n \n\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\nNote:<\/strong>\u00a0The \u201cusable\u201d CBM is often slightly less than the theoretical maximum due to packaging, pallets, and the need for safe loading and unloading.<\/p>\n
For example, a 20\u2019 container usually fits about 26-28 CBM of cargo, even though its internal capacity is 33 CBM.<\/span><\/p>\n
How Many Boxes Fit in a Container?<\/strong><\/h3>\n
Once you know your total CBM, divide the container\u2019s usable CBM by your shipment\u2019s CBM per box to estimate how many boxes will fit. Online calculators make this step a breeze.<\/span><\/p>\n
Additional Tips for Maximizing CBM Usage<\/b><\/h2>\n
To make the most of your shipping budget, try these tips:<\/span><\/p>\n
Use Uniform Boxes<\/b><\/h3>\n
Standardizing your packaging makes it easier to stack and reduces wasted space.<\/span><\/p>\n
Disassemble Furniture<\/b><\/h3>\n
Large furniture can take up loads of CBM. Break it down to reduce volume and improve packing density.<\/span><\/p>\n
Avoid Overpacking<\/b><\/h3>\n
Overhanging or oddly shaped boxes might make it harder to stack and can waste space in a container.<\/span><\/p>\n
Work with a Freight Forwarder<\/b><\/h3>\n
They\u2019ll help you calculate CBM correctly and suggest the best way to consolidate or arrange your shipment.<\/span><\/p>\n
Consider Shrink Wrapping or Palletizing<\/b><\/h3>\n
Depending on what you\u2019re shipping, the use of pallets might help protect goods and improve loading\/unloading, but it can also increase CBM slightly.<\/span><\/p>\n
