Measurement Ton (M/T or CBM/T) is a unit of measurement used in international shipping to calculate freight for light and bulky cargo. Typically, 1 cubic meter (or 40 cubic feet) equals 1 measurement ton. When cargo is large in volume but light in weight, the shipping company charges freight by measurement ton; otherwise, by weight ton. It is commonly used in container transport and breakbulk shipping, especially for low-density goods such as textiles, plastics, and furniture. Note: Different shipping companies or routes may use different conversion standards (e.g., 1 measurement ton = 1 cubic meter or 1.133 cubic meters), and it must be compared with the weight ton, with the higher one used for charging. The difference from weight ton: weight ton is based on 1 metric ton (1000 kg) or 1 long ton (1016 kg), while measurement ton is based on volume. Foreign trade practitioners should confirm the freight ton standard before booking to avoid disputes.
📝 Examples
1. This batch of foam plastic products has a volume of 15 cubic meters and weighs only 2 metric tons. The shipping company charges freight by measurement ton at USD 80 per measurement ton, so the total freight is USD 1200. (Note: Because the cargo is light and bulky, measurement ton is used.)
2. When quoting, we need to compare weight ton and measurement ton, and take the higher as the freight ton. In this case, measurement ton is 12 and weight ton is 10, so freight is calculated based on 12 measurement tons. (Note: Demonstrates the principle of selecting the freight ton.)
