Good Delivery update: silver bars and weight stamps

1,000oz Comex Silver bars from LBMA Good Delivery refiners are acceptable

LBMA has received a number of queries regarding Silver London Good Delivery Bars (LGDB) and COMEX silver bars, particularly with regards to the marking of weight on the bars. As per existing protocols, 1,000oz Comex Silver bars from LBMA Good Delivery refiners are acceptable in London, even if the weight is stamped on the bar.

Any weights stamped on Silver London Good Delivery Bars will be ignored and the bars will be weighed in accordance with the Good Delivery Rules upon arrival in London (See GDL Rules - Appendix F)

Stamping of weights on bars will not render the bar as Non Good Delivery (NGD).

LBMA will continue to work with the CME Group regarding global precious metals standards, which includes silver bar marks/specifications and approved refiners.
