Good Delivery Bars

Good delivery bars are a specific set of requirements made by The London Bullion Market Association (LBMA) that is used to determine whether the gold bars are high-grade and fit for transactions to major international gold bar markets that take place in New York, Hong Kong, London, Zurich, Sydney and Tokyo as well as in the gold vaults of central banks, IMF and government Gold bars that meet the criteria and standards of this rule, are stamped by approved assayers and melters from one of the authorized sixty companies worldwide, sealed and marked with a serial number, fineness (displays up to four figures), year of manufacture (expressed in four digits), and gold content measured in troy ounces (minimum of 350 to a maximum of 430). Good delivery bars are notable for their weight and density. To pass this criteria, dimensions of gold bars must be 210-290 mm in Length, 55-85 mm in Width, and 24-45 mm in height. It is also specified that the bars must be of good appearance. If the gold bars do not successfully meet the said requirements they are chopped as “NGD” Non-Good Delivery Bars to set them aside from conforming bars.
