The value of a coal cargo is determined by testing a sample collected manually or by a mechanical coal sampling system. If the sampling method or the sample preparation is biased or inconsistent, the value of the cargo can be inaccurately or imprecisely determined. This results in the cargo being over-or under-valued and
