In everyday life, we often hear net weight and gross weight referring to cargo weight. Many of you will not be able to understand this concept how. Soon we also find out what the net weight and gross weight are offline!
1. What is net weight?
Net weight translated in Vietnamese language means "net weight". Literally it is the weight of an object excluding the weight of packaging materials, containers or other packaging.
Net Weight, abbreviated as NW, is usually written on the outside of the packaging by the manufacturers.
Example: A package of beef noodle soup that says Net Weight 120g. That means the total weight of all the ingredients inside including oil, salt, dry pho, ... is 120g, excluding the weight of the packaging.
Formula for calculating net weight
Net weight is determined by the value of gravity (g) acting on an object. You can refer to the below formula:
W = m x g or W = m.g
In addition, if calculated by force, there is the following formula: F = m.g
Inside:
F is the weight calculated for the scars N
M denotes the calculated mass as Kilogram.
G denotes the acceleration of gravity (m / s2)
2. What is Gross Weight?
Gross weight is abbreviated above the packaging as G. Weight this means the weight of the whole package (including the weight of the NW object and the cover / box) it means English translated is the “actual weight” ie the weight including packaging. In addition, we also see a number of quantities similar to Net weight, denoted N. Weight, this is a quantity representing the weight of an object, also known as net weight, ie weight after subtracting the bag. envelope out.
The general convention for IATA aviation associations, the actual weight will be converted through the formula:
V.W = (Length x Width x Height) / 6000
Of which: The unit of calculation is Cm (Centimeter)
3. Comparison between Gross Weight and Net Weight
As shared, Gross Weight is the total weight of the cargo, while Net Weight is only the weight of the cargo. So we can see that GW includes NW in it.
You should note that later in freight people will usually charge Gross Weight instead of NW. So you need to optimize this unit to save unnecessary costs. Especially important for transporting goods by plane.
Currently, establishments and companies that manufacture, import and trade with packaging must comply with regulations No. 21/2014 on measurement for pre-packed products of the Ministry of Science and Technology.
4. How to optimize Gross Weight when packing and shipping
To optimize GW, we need to rely on 1 of 2 main factors: NW or the weight of packaging. As for goods, we are very difficult to change and it is almost predetermined, so there is only the weight and size of the packaging that we can choose from.
To ensure the goods are safe from scratches or limited impact, the packer will usually wrap an air-foam or foam film from Foam material. And outside the package will be packed an extra layer of cartons, depending on the type of goods that use can be a 3-layer, 5-layer or 7-layer carton.
5. Refer to some more packing specifications
Before shipping all goods should be packed securely.
The packaging should be selected for durability, sure, but should not be used too large compared to the goods to save transportation costs.
At that time, the package needs careful dunnage to limit the movement of goods.
Use tape to seal the product.
Packages must be printed with full product and manufacturer information.
= >> You should order cartons of moderate size, so order new instead of choosing old cartons or buying pre-made cartons.
With the above sharing hope will help you understand and distinguish the net weight and gross weight. To reduce freight, you need to know how to optimize the gross weight appropriately!
