I. Calculation method of cross-border air freight:
A weight of 1m³ greater than 166.67 kg is called heavy cargo, less than 166.67 kg is called bubble cargo. Heavy cargo shall be charged according to actual gross weight, while bubble cargo shall be charged according to volume weight.
Matters needing attention:
1. CBM is short for CubicMeter, meaning m³.
2, some volume weight according to length (cm) × width (cm) × height (cm) ÷5000 calculation, not common, generally only express companies use this algorithm.
3, in fact, the division of air cargo transportation of heavy cargo and cargo much more complex, depending on the density, for example, a 1:30 0, 1, 400, 1:500, 1:800, 1:1000 and so on. The ratio is different, the price is different.
4. In order to make full use of the space and carrying capacity of the aircraft, heavy cargo and empty cargo are generally reasonably matched. Cross-border air stowage is a technical activity -- a good match can make full use of the limited space resources of the aircraft, and even a good one can greatly increase additional profits. Too much heavy cargo wastes space (overweight if not full) and too much cargo wastes deadweight (full if not full).
Ii. Calculation method of cross-border shipping:
1. The division of heavy cargo and light cargo by cross-border sea transportation is much simpler than that by cross-border air transportation. China's cross-border sea transportation LCL business basically distinguishes heavy cargo and light cargo according to the standard of 1m³ equals 1 ton.
In the case of cross-border LCL, heavy cargo is rare and basically light cargo. Besides, the freight of cross-border LCL is calculated according to volume, which is fundamentally different from that of cross-border air freight by weight, so it is relatively simple. A lot of people do a lot of cross-border shipping but have never heard of light and heavy goods because they rarely use them.
2, according to the ship stowage, all cargo stowage factor is less than the cargo ship capacity coefficient, called heavy stuff (DeadWeightCargo/HeavyGoods). All cargo stowage factor is greater than the cargo ship capacity coefficient, called light goods/cargo (MeasurementCargo/LightGoods).
3. According to the calculation of freight and international shipping business practice, cargo with stowfactor less than 1.1328m³/ ton or 40 cubic feet/ton is called heavy cargo. Cargo with a stowfactor greater than 1.1328m³/ ton or 40 cubic feet/ton is called light cargo.
The concepts of heavy and light cargo are closely related to stowage, transportation, storage and billing. The carrier or freight forwarder distinguishes between heavy cargo and light cargo/empty cargo according to certain criteria.
The density of LCL for cross-border sea transportation is 1000KGS/1CBM. The cargo uses tons to compare the cubic number. If the cargo is larger than 1, it is heavy cargo, and if the cargo is smaller than 1, it is empty cargo. However, many voyages are now limited to weight, so the ratio is adjusted to about 1 ton /1.5CBM. Cross-border air transport, based on the ratio of 1000 to 6, is equivalent to 1CBM=166.6KGS, 1CBM over 166.6 is heavy cargo, on the contrary, it is bubble cargo.
