When shipping goods internationally, it is important to understand the concept of volumetric weight. Volumetric weight, also known as dimensional weight, is a calculation used by shipping companies to determine the cost of shipping a package. In simple terms, it is a way of pricing based on the amount of space a package occupies in relation to its actual weight.
How Volumetric Weight is Calculated
The formula used to calculate volumetric weight varies between shipping companies, but it typically involves multiplying the length, width, and height of the package and dividing the result by a volumetric factor. The volumetric factor is a number that represents the amount of space required to ship one kilogram of weight. For example, if the volumetric factor is 5, then a package that weighs 5 kilograms but takes up 25 kilograms of space will be charged as if it weighs 25 kilograms.
The exact formula for calculating volumetric weight can vary depending on the shipping company and the units used to measure the package. However, the general formula can be written as:
Volumetric Weight = (Length x Width x Height) / Volumetric Factor
For example, if you have a package with dimensions of 50cm x 40cm x 30cm, and a volumetric factor of 6000, the volumetric weight would be:
Volumetric Weight = (50 x 40 x 30) / 6000 = 10 kg
This means that if the actual weight of the package is less than 10 kg, but the volumetric weight is 10 kg or more, then the shipping company will charge based on the volumetric weight instead of the actual weight.
For sea freight and air freight DDP shipping, the volumetric factor is normally 6000. However, for air courier express shipping, the volumetric factor is normally 5000. Therefore the volumetric weight of a sea freight/air freight DDP shipment is normally higher than the volumetric weight of an air courier express shipment.
Why Volumetric Weight is Important
Volumetric weight is important because it allows shipping companies to charge based on the amount of space a package occupies, rather than just its actual weight. This is especially important for larger, lighter packages that take up a lot of space but don't weigh much.
For example, let's say you want to ship a package that weighs 2 kg, but it is large and takes up a lot of space. Without volumetric weight, the shipping company would charge you based on the actual weight of the package, which is 2 kg. However, with volumetric weight, the shipping company would calculate the package's volumetric weight and charge you based on that instead. If the volumetric weight is higher than the actual weight, you may end up paying more for shipping than you would if the cost was based solely on the actual weight.
Factors That Affect Volumetric Weight
There are several factors that can affect the volumetric weight of a package, including:
Size: As the size of a package increases, so does its volumetric weight. Shipping companies charge more for larger packages, so it is important to pack your goods as efficiently as possible to avoid unnecessary charges.
Shape: The shape of a package can also affect its volumetric weight. Irregularly shaped packages may require more space to be shipped, resulting in a higher volumetric weight.
Density: The density of the materials being shipped can also affect the volumetric weight. For example, a package containing lightweight materials such as foam or cotton may have a higher volumetric weight than a package containing denser materials such as metal or glass.
Packaging: The type of packaging used can also affect the volumetric weight. Lightweight packaging materials such as bubble wrap or foam can add to the overall volume of the package, increasing its volumetric weight.
How to Reduce Volumetric Weight
There are several ways to reduce the volumetric weight of a package, including:
Use smaller packaging: Using smaller packaging can help reduce the volumetric weight of a package. When selecting packaging, it is important to choose the smallest possible size that will adequately protect your goods.
Use denser materials: Using denser materials can also help reduce the volumetric weight of a package. For example, if you are shipping clothing, consider folding it tightly to reduce its volume.
Use efficient packaging: Using packaging that is specifically designed to reduce volumetric weight can be a good way to save money on shipping costs. For example, some packaging materials are made from lightweight but strong materials that help reduce the overall weight of the package.
Use a professional packaging service: Many shipping companies offer professional packaging services that can help you reduce the volumetric weight of your package. These services often include custom-designed packaging that is specifically tailored to your needs, which can help reduce the overall volume of the package.
Understanding volumetric weight is an important aspect of international shipping. By knowing how it is calculated and the factors that can affect it, you can take steps to reduce the cost of shipping and ensure that your goods arrive at their destination safely and securely. If you are unsure about how to calculate the volumetric weight of your package, or if you have any other questions about international shipping, be sure to consult with a shipping professional who can help guide you through the process.
