I have a scenario in jewelry industry. We buy the gold bullion from different vendors. The vendors are expected to supply gold of 99.5 % purity (24 carat gold). At the time of procurement there will be a quality inspection. If the gold is found to be impure, i.e. Less than 99.5%- the gold bullion is accepted but a lower price. Impure gold is then sent for purification process. Please suggest how to map this in QM.
Thanks in advance
