Accurate Verified Gross Mass (VGM) declaration before container loading is critical for maritime safety and supply chain compliance. This guide provides a clear framework for completing VGM requirements efficiently, ensuring cargo reaches its destination safely and on schedule.
Understanding VGM Requirements
Verified Gross Mass represents the total weight of a shipping container, including both its cargo and the container's own weight. International Maritime Organization (IMO) regulations mandate VGM submission for all containers prior to loading to maintain proper vessel stability and prevent accidents caused by weight miscalculations.
VGM Submission Methods
While VGM information typically accompanies shipping instructions, separate declaration may be necessary. The standard submission process involves:
- Account Access: Navigate to the shipping platform and authenticate using valid credentials.
- Locate Shipment Details: Search for the specific consignment using the Bill of Lading (B/L) or container reference number.
- Access VGM Section: Select the designated container management interface from the shipment overview page.
-
Data Entry:
Input the precise VGM measurement and select the approved calculation methodology:
- Method 1 (Weighing): Direct measurement of the fully loaded container
- Method 2 (Calculation): Summation of all cargo weight plus the container's tare weight
Determining Container Tare Weight
For calculation-based declarations, the container's empty weight can be found:
- On the container door's manufacturer plate (displayed in kilograms or pounds)
- Through specialized container weight reference tools
Critical Compliance Considerations
Maritime operators emphasize several non-negotiable requirements:
- Absolute precision in weight declarations to prevent operational delays and safety hazards
- Strict adherence to submission deadlines for loading authorization
- Full alignment with international shipping regulations and carrier-specific policies
Frequently Addressed Concerns
VGM uncertainty: Consultation with qualified freight professionals is recommended when weight verification proves challenging.
Data amendments: Most systems permit VGM adjustments prior to the submission cutoff.
Cost implications: While standard declarations typically incur no fees, inaccurate submissions may result in penalty assessments.
