Calculating Cubic Meters (CBM) is a fundamental step when shipping goods via ocean freight from China to Thailand. Whether you’re involved in high volume export China to Thailand, arranging B2B shipping solutions for Thailand imports, or utilizing sea shipment provider China to Thailand, an accurate CBM calculation directly impacts your shipping costs and logistics planning. Here’s a detailed guide on how to calculate CBM for Thailand ocean freight.
1. Understand the Importance of CBM
CBM represents the volume of your cargo and is a key factor in determining ocean freight rates. Shipping companies use CBM, along with the weight of the goods, to assess the space your shipment will occupy in a container or on a vessel. In many cases, freight charges are based on either the weight (per kilogram or ton) or the volume (CBM) of the cargo, whichever is greater. This is known as the “weight or measurement” (W/M) principle. So, an accurate CBM calculation helps you estimate costs precisely and avoid unexpected expenses.
2. Measure Your Cargo Dimensions
a. Individual Item Measurements
If you’re shipping individual items, use a measuring tape or ruler to measure the length, width, and height of each item in meters. For example, if you have a box of consumer goods, measure the longest side as the length, the next-longest side as the width, and the shortest side as the height. Record these measurements accurately.
b. Multiple Items or Palletized Cargo
For multiple items packed together or palletized cargo, measure the overall dimensions of the packed unit. This includes the length, width, and height of the entire pallet or the combined package. Make sure to account for any additional space occupied by packaging materials, such as pallets, crates, or shrink wrap.
3. Calculate CBM for a Single Item
The formula for calculating CBM is simple: CBM = Length (m) × Width (m) × Height (m). For instance, if an item has a length of 0.5 meters, a width of 0.3 meters, and a height of 0.2 meters, the CBM calculation would be: 0.5 × 0.3 × 0.2 = 0.03 CBM.
4. Calculate CBM for Multiple Items
a. Items Packed Separately
If you have multiple items packed separately, calculate the CBM for each item using the formula above and then sum up the individual CBM values. For example, if you have three boxes with CBM measurements of 0.05, 0.08, and 0.12 respectively, the total CBM for these three items would be 0.05 + 0.08 + 0.12 = 0.25 CBM.
b. Items Packed Together
When items are packed together into a single unit, such as on a pallet, use the overall dimensions of the packed unit to calculate the CBM. Suppose a palletized cargo has a length of 1.2 meters, a width of 1 meter, and a height of 1.5 meters. The CBM would be 1.2 × 1 × 1.5 = 1.8 CBM.
5. Consider Special Cases
a. Irregularly Shaped Items
For irregularly shaped items, you can use approximation methods. One approach is to measure the item as if it were a rectangular box that encloses the item, using the maximum length, width, and height dimensions. Another option is to break the item into smaller, more regular – shaped parts, calculate the CBM for each part, and then sum them up.
b. Volume – Heavy vs. Weight – Heavy Cargo
As mentioned earlier, ocean freight rates are often based on the W/M principle. If your cargo is volume – heavy (the calculated CBM results in a higher chargeable weight than the actual weight), you’ll be charged based on the CBM. Conversely, if it’s weight – heavy, the charge will be based on the weight. Understanding this dynamic helps you optimize your shipping costs. You might consider ways to reduce the volume of your cargo, such as more efficient packaging, if it’s volume – heavy.
