“Good Delivery” in the gold bullion trade refers to the specification set by the London Bullion Market Association (LBMA) that describes the physical characteristics that gold and silver bars must meet in order to be accepted for trading on the wholesale London bullion market.
This guarantee means that each gold bar is accurately assayed, meaning its purity has been measured, and is over 99.5% pure gold. The gold bars must also meet certain requirements regarding their appearance, weight, marks, fineness, and dimensions.
“Good Delivery Bars” are an internationally accepted trading standard used by gold dealers, traders, and bullion banks worldwide to trade and deal in large quantities of gold on the international market.
