Container Weight Verification Solutions and Services for Ports Serving the Gulf of Mexico

The Safety of Life at Sea (SOLAS) treaty requires that all containers have a verified weight certificate before being loaded on to a ship. The containers Verified Gross Mass (VGM) must be communicated to the carrier/marine terminal, in accordance with their specified times and methods, and thereafter used in the ship stowage planning process. As a shipper you can achieve weight verification by one of the following methods below:

WEIGHT VERFICATION METHOD 1: Weigh the container and its contents on a calibrated and certified instrument such as a weighbridge, load cell system or other piece of suitable equipment.

WEIGHT VERFICATION METHOD 2: Weigh all of the cargo items being packed into the container along with dunnage, securing and lashing materials and the tare weight of the container and aggregate them together to arrive at an aggregated weight.

Estimating the weight of a container’s contents is not permitted.

Per the SOLAS international maritime safety treaty, all weighing equipment used to provide a verified weight must be calibrated and certified to meet the accuracy standards and requirements of the State (Country) in which the equipment is being used.
