Dead Weight refers to the actual physical weight of a shipment measured using a weighing machine or scale before it is shipped. It represents the real mass of the package, including the product, packaging material, and box weight. In logistics and eCommerce shipping, dead weight is one of the main factors used by courier companies to calculate shipping charges.

Courier partners usually compare dead weight with volumetric weight to determine the chargeable weight of a shipment. If the package is small but heavy, the dead weight is generally used for billing. However, if the package is lightweight but occupies more space, volumetric weight may become applicable. The higher value between dead weight and volumetric weight is usually considered the final chargeable weight.

Understanding dead weight is important for eCommerce sellers because it directly affects shipping costs and courier pricing. Accurate weight measurement helps avoid weight discrepancies, extra shipping charges, and delivery delays. Proper dead weight management also improves packaging efficiency and helps businesses optimize logistics costs for daily shipments
