What Is Chargeable Weight? Gross Weight vs Volumetric Weight in Shipping

If you have ever requested a freight quotation from a forwarder, you must have noticed three confusing terms on the invoice: Gross Weight, Volumetric Weight, and Chargeable Weight.

Many new importers wonder: Why is the shipping cost calculated based on a higher weight instead of the actual weight of my goods?

This article will simply and clearly explain how freight forwarders calculate shipping weights, helping you avoid unexpected extra charges and understand every cost of your China import logistics.

Gross weight is the real physical weight of your cargo, measured by a weighing scale.

It includes the weight of the products, outer carton packaging, and all accessories. This is the most intuitive weight data and is fixed after the goods are packed.

Example Your goods weigh 300kg after full packaging — this is your gross weight.

Shipping carriers charge freight based on space occupation in containers or aircraft, not just actual weight.

Some goods are very light but bulky, such as paper products, textiles, and handicrafts. Although they weigh little, they take up a large amount of container space. If charged by gross weight only, carriers will suffer huge losses.

Therefore, the industry has a unified standard for volumetric weight (calculated from cargo volume).

Common Shipping Calculation Formula (Air & Express) Volumetric Weight (kg) = Length(cm) × Width(cm) × Height(cm) ÷ 6000

Example If your cargo is 1 CBM with light weight, its calculated volumetric weight will be much higher than the gross weight.

Chargeable weight is the final weight used to calculate your shipping cost.

Freight forwarders and carriers follow one core rule:charge by the higher one between gross weight and volumetric weight.

• Heavy goods: Actual weight > Volumetric weight → Charge by gross weight
• Light/bulky goods: Volumetric weight > Actual weight → Charge by volumetric weight

Real Case Scenario Gross Weight: 100kg Volumetric Weight: 167kg Final Chargeable Weight: 167kg The shipping fee will be calculated based on 167kg, not the actual 100kg.

Most new importers only focus on the actual weight of goods and feel confused about the high shipping cost. In fact, light and large-volume cargo always generates higher logistics costs.

For long-term import business, you can optimize packaging to reduce volumetric weight: compress packaging, use slim cartons, and avoid excessive filler materials, which can effectively cut down your shipping budget.
