Avoiding Forwarder Markups: How to Calculate Real Volume Weight for China Shipments
In international shipping, forwarders often charge based on the higher of the actual weight or volumetric weight of a package. To avoid unnecessary markup by forwarders, understanding and accurately calculating the real volumetric weight is crucial. Below is a detailed guide:
Volumetric Weight Calculation Formula
Volumetric weight, also known as dimensional weight, is a method used by shipping carriers to account for the space a package occupies during transit. The basic formula for calculating volumetric weight is:
Volumetric Weight = (Length × Width × Height) / Dimensional Factor
The dimensional factor varies depending on the mode of transportation and carrier. Common dimensional factors include 5000 and 6000. For courier shipments from China (e.g., UPS, TNT, FedEx, DHL), the dimensional factor is typically 5000 cm³/kg. For air freight shipments from China, the dimensional factor is usually 6000 cm³/kg.
Calculation Steps
- Measure the Package Dimensions: Measure the length, width, and height of the package in centimeters. If measured in meters, convert them to centimeters (1 meter = 100 centimeters).
- Calculate the Volume: Multiply the length, width, and height to obtain the package volume in cubic centimeters (cm³).
- Divide by the Dimensional Factor: Divide the volume by the dimensional factor (5000 or 6000) to derive the volumetric weight.
- Compare with Actual Weight: Compare the volumetric weight with the actual weight of the package. The higher of the two will be used as the chargeable weight.
Examples of Calculation
- Courier Shipment: Suppose a package from China has dimensions of 100 cm × 80 cm × 60 cm and an actual weight of 50 kg. Using the formula (100 × 80 × 60) / 5000 = 96 kg. Since the volumetric weight (96 kg) is higher than the actual weight (50 kg), the chargeable weight will be 96 kg.
- Air Freight Shipment: If a package has dimensions of 90 cm × 60 cm × 40 cm and an actual weight of 15 kg, the volumetric weight is calculated as (90 × 60 × 40) / 6000 = 36 kg. Here, the volumetric weight (36 kg) exceeds the actual weight (15 kg), so the chargeable weight will be 36 kg.
How to Verify Volumetric Weight
To avoid discrepancies in volumetric weight calculations by forwarders, you can use the official weighing videos from 17TRACK for verification. The process is as follows:
- Access 17TRACK’s Official Website: Visit the official website of 17TRACK, a trusted logistics tracking platform.
- Enter Shipment Tracking Number: Input your shipment’s tracking number on the homepage and click “Track.”
- Locate the Weighing Video: Once the tracking details page loads, locate the “Weighing Video” section. Click to view the official weighing video uploaded by the logistics service provider.
- Compare and Verify: Use the measurements in the weighing video to recalculate the volumetric weight using the formula and compare it with the forwarder’s calculation to ensure accuracy.
Tips for Reducing Volumetric Weight Costs
- Optimize Packaging: Avoid excessive packaging. Use the smallest carton size necessary to protect the goods while minimizing empty space. For lightweight items, consider compressing them or using space-efficient packaging.
- Consolidate Shipments: If multiple small packages are being shipped to the same destination, consolidate them into a single larger package. This reduces the overall volumetric weight and lowers shipping costs.
- Negotiate with Forwarders: For long-term or large-volume shippers, negotiate with forwarders to secure a more favorable dimensional factor or request discounts on volumetric weight charges.
Why Accurate Volumetric Weight Calculation Matters
Accurate volumetric weight calculation is essential for both carriers and shippers. For carriers, it ensures fair compensation for the space occupied by bulky, lightweight packages. For shippers, it helps avoid unexpected shipping costs due to inaccurate weight estimates. Proper calculation ensures transparent and equitable cost allocation, benefiting both parties.
