VGM short for Verified Gross Mass, namely verified gross mass of loaded containers. The rule took effect globally on July 1, 2016, formulated by IMO under the SOLAS Convention. The core principle is "No VGM, No Load". Without qualified VGM data submitted before cut-off time, terminals and carriers will refuse to load containers onto vessels.
VGM refers to the total weight including cargo, pallets, packing & securing dunnage plus container tare weight. Estimated weight is not accepted; weights must come from calibrated certified weighing equipment. There are two officially approved weighing methods.
1.Weigh the fully stuffed container as a whole after loading completion.
2.Weigh all goods and auxiliary materials separately, then add the container tare weight marked on the container door.
According to international regulations, the shipper listed on the bill of lading bears legal responsibility for the authenticity of VGM data. Freight forwarders can assist in submission, but cannot take primary liability for false declaration. Different ports and carriers set their own weight tolerance standards, normally ±5% or 1 ton, whichever is smaller.
Many exporters encounter troubles caused by delayed VGM submission, weight deviation or incorrect container number information. Late submission leads to missing vessel and costly rescheduling. Serious misdeclaration may bring fines, customs inspection and cargo detention.
Suggestions for foreign trade enterprises: Arrange weighing reasonably during stuffing, confirm VGM submission deadline with forwarder in advance, double-check container numbers and weight data, and reserve weighing records for verification.
