Verified Gross Mass and Container Weight Rules

Written by

Quick answer: Under international maritime safety rules (SOLAS), the shipper must provide the verified gross mass (VGM) of each packed container before it is loaded on a ship. VGM can be found by weighing the packed container or by adding the weights of all contents and the container’s tare. Accurate VGM keeps ships safe and avoids loading delays.

Key takeaways – VGM is required for every packed export container. – The shipper is responsible for providing it. – Two methods are accepted. – Wrong or missing VGM can stop loading.

Why VGM exists

Incorrect container weights can affect ship stability and cause accidents. The SOLAS rule on VGM was introduced to make sure ships know the real weight of each container.

Two methods

Method How it works
Method 1 Weigh the packed and sealed container on certified equipment
Method 2 Weigh all packages and materials, add container tare weight

Method 2 must follow procedures accepted by the national authority.

What is included in VGM

  1. Cargo weight, including bags and liners.
  2. Pallets and dunnage.
  3. Securing materials.
  4. Container tare weight.

Responsibilities

The shipper named on the bill of lading is responsible for the VGM. In practice, exporters often work with freight forwarders and terminals to obtain and submit it.

Deadlines

Shipping lines set cut-off times for VGM submission. Late or missing VGM can mean the container misses the vessel.

Road weight limits

Besides VGM, road transport limits apply at origin and destination. A container that is legal at sea may still be too heavy for local roads. Plan loads accordingly.

Tips for exporters

  • Use calibrated scales.
  • Record bag weights and counts.
  • Check tare weight on the container door.
  • Submit VGM early.
  • Keep records with shipping documents.

Checking the numbers

Compare the VGM with the packing list and invoice weights. Large differences may point to errors in counting, tare weights or scale readings. Correct these before the documents are finalised to avoid questions at the port.

Avoiding common weight problems

Weight problems often come from small gaps in communication. The shipper should know who is responsible for declaring the verified gross mass and by which deadline. The weighing method used should be agreed and documented. Packing lists, bag counts and declared weights should match each other, with tare weights for the container and any packing material included. Checking road weight limits in the destination country also matters, since a container that is legal at sea may still be too heavy for local trucks. Clear figures on the documents help shipments move through ports without holds or extra costs.
