London Good Delivery Standards

Manufacturing Term

London Good Delivery Standards (LGDS) is a set of specifications and guidelines established by the London Bullion Market Association (LBMA) for the production and refining of gold and silver bars. The LGDS serves as the benchmark for quality and authenticity in the precious metals industry.

The LGDS specifies the weight, dimensions, fineness, and marking requirements for gold and silver bars. The weight must be between 350 and 430 ounces for gold bars and between 750 and 1,100 ounces for silver bars. The dimensions must be within certain tolerances, and the fineness must be at least 995 parts per thousand for gold and 999 parts per thousand for silver. The bars must also be marked with the weight, fineness, and refinery name.

Manufacturing companies use LGDS when they require large quantities of gold or silver bars for their operations. The standard ensures that the bars are of a consistent size, weight, and purity, which is essential for manufacturing products that require precise amounts of precious metals like electronics, industrial catalysts, medical equipment, and even jewelry. Using LGDS accredited bars also provides assurance that the precious metals used in manufacturing are of high quality and sourced ethically.
