# Independent Verification of Cargo Weights

*Last updated: 2026-06-24*

> Freight forwarders, shipping lines, and port authorities rely on independent verification of cargo weights to have the declared mass of a shipment confirmed by a neutral third party.

Freight forwarders, shipping lines, and port authorities rely on independent verification of cargo weights to have the declared mass of a shipment confirmed by a neutral third party. The process is firmly embedded in container shipping: under SOLAS Verified Gross Mass (VGM) requirements, shippers must confirm the gross weight of a packed container before vessel loading, using an approved method. Certified weight records carry legal standing, reduce liability exposure for shippers and carriers alike, and prevent overloading damage to vessels, port equipment, and road infrastructure. In road transport, independent weight checks serve equally to enforce permissible axle-load limits.
