Consistency matters in antimony concentrate supply

Understanding the subject

A buyer may need repeated lots rather than one attractive sample. An initial result should therefore be considered alongside the proposed lot definition and the information available about variability.

What it means in practice

A recurring programme benefits from clear specifications, shipment identification and an agreed document set. The buyer should know how changes in grade or impurities will be reported and reviewed.

Bring it into your next discussion

Discuss the difference between an indicative sample and the material offered for delivery. A transparent description of variability can support a better commercial relationship than presenting a single result as a universal specification.

• Ask whether a sample represents a defined lot.
• Agree which parameters are reported per shipment.
• Record how deviations will be reviewed.
