Why Product Weight Listed Online Differs from Shipping Weight
Quick Answer
Product weight describes the item itself, while shipping weight may include packaging or a carrier’s dimensional-weight calculation. Carriers generally charge using whichever billable weight is higher.
Key Takeaways
- Actual weight is measured on a scale after the order is packed.
- Dimensional weight is calculated from the package’s external size.
- Large protective boxes can increase billable weight even when the product is lighter.
Before You Place an Order
Confirm the seller’s identity, written specifications, payment protection, delivery method, packaging, customs terms, and support process. Keep a copy of the product page and order confirmation so any difference can be documented clearly.
Shipping Weight Explained
Shipping carriers like FedEx, DHL, and UPS use two different methods to calculate shipping costs.
Your final shipping charge depends on whichever weight is higher.
1. Actual Weight
Actual weight is the real physical weight of the package placed on a scale.
For example:
Package on scale = 36 kg
Actual weight = 36 kg
This method is usually used for compact and heavy items.

2. Volumetric (Dimensional) Weight
Volumetric weight is based on the size of the package, not just the physical weight.
Large packages take up more space during transportation, so carriers calculate shipping weight using package dimensions.
Common Formula
Length × Width × Height ÷ Dimensional Factor
Examples:
FedEx / UPS: ÷ 139 (inch system)
DHL Express: ÷ 5000 (cm system)
If the dimensional weight is higher than the actual weight, the carrier charges based on the dimensional weight.

Why Website Weight May Differ From Actual Shipping Weight
For example, the 36 kg listed on our website is an estimated chargeable shipping weight based on standard packaging and average carrier calculations.
However, the final shipping weight may vary slightly because of different factors:
- Packaging size differences
- Carton deformation during packing
- Carrier measuring methods
- Volumetric weight calculations
- Rounding rules used by shipping companies
To avoid unexpected shipping issues, we usually leave a small safety margin when listing estimated shipping weights.
Additional Electric Features
If you customize additional electric functions, extra motors and internal components are installed inside the doll’s body.
This will increase the final package weight and may affect the courier’s chargeable shipping weight.
Final Note
FedEx, DHL, and UPS always charge based on two calculation methods:
✅ Actual Weight
or
✅ Volumetric Weight
Whichever is higher.
We always do our best to provide accurate shipping estimates before shipment.
