How are heavy goods and light goods defined in different modes of transportation?

How to define heavy cargo and light cargo (also called soaking and dumping) in logistics transportation? First, you need to understand the actual weight and volume weight: (1) Actual Weight, which is the weight obtained according to weighing (weighing), including actual gross weight (Gross Weight, GW) and actual net weight (Net Weight, abbreviated as NW), the most common is the actual gross weight. (2) Volume weight (Volumetric Weight or Dimensions Weight), that is, the weight calculated from the volume of the cargo according to a certain conversion factor or calculation formula. Simply put, if the actual weight of the goods is greater than the volume weight, it is heavy goods, and vice versa, it is light goods (also known as soaking goods and dumping goods). However, different modes of transportation have different definitions of heavy goods and light goods. 1. Shipping (1) From the perspective of ship stowage and stowage, any cargo with a cargo stowage factor less than the ship’s cargo volume factor is called deadweight cargo or heavy goods; where the cargo stowage factor is greater than the ship’s cargo volume Coefficient goods are called light goods, or light goods (measurement cargo or light goods). (2) From the perspective of calculating freight rates, and in accordance with international shipping business practices, any cargo with a cargo stowage factor less than 1.1328 cubic meters/ton or 40 cubic feet/ton is called heavy cargo; where the cargo stowage factor is greater than 1.1328 cubic meters The cargo of meters/ton or 40 cubic feet/ton is called light cargo. (3) The distinction between light cargo and heavy cargo in LCL is based on the weight per cubic meter. In international maritime LCL, it is usually 1 cubic meter u003d 1 ton. For example, if the volume of the cargo is 1 cubic meter and the weight is less than 1 ton, it is considered as light cargo, and the weight is more than 1 ton as heavy cargo. However, heavy cargo is rare in ocean LCL, and it is basically light cargo, and ocean LCL is calculated based on volume, which is fundamentally different from air freight based on weight, so it is relatively simple. Many people do a lot of ocean freight, but have never heard of light or heavy cargo, because they are basically not used. 2. Air transport and express delivery regulations: length (cm) × width (cm) × height (cm) ÷ 6000 u003d volume weight (KG), that is, 1CBM≈166.66667KG. Irregular items: the longest (cm) × widest (cm) × highest (cm) ÷ 6000 u003d volumetric weight (KG), that is, 1CBM≈166.66667KG. This is an internationally accepted algorithm. In short, one cubic meter of goods greater than or equal to 167 kilograms is considered heavy goods and is charged according to actual weight. If 1 cubic meter is less than 167 kg, it will be charged when the cargo weighs 167 kg, which is considered light cargo. The weight ratio of air transport is 1:167. For example: the actual gross weight of one air cargo is 95 kg and the volume is 1.2 cubic meters. According to the coefficient of air freight 1:167, the volume weight of this cargo is 1.2x167u003d200.4 kg, which is greater than the actual gross weight of 95 kg, so this cargo, Airlines will charge based on volumetric weight, not actual gross weight. Another example: the actual gross weight of a ticket of air cargo is 560 kg, and the volume is 1.5 CBM. According to the coefficient of air freight 1:167, the volume weight of this ticket is 1.5x167u003d250.5 kg, which is less than the actual gross weight of 560 kg, so this cargo is For heavy cargo, the airline will charge according to the actual gross weight, not the volume weight. The classification of heavy goods and light goods in this article is for reference only. There are often some gaps between theory and practice, and further consultation with relevant logistics companies is required.
