Who determines average tare weights?

The determination of average tare weights is typically the responsibility of a weigh master. A weigh master is a certified individual who oversees weight measurements and ensures compliance with applicable regulations. Their role includes accurately assessing the tare weights, which are essential for calculating the net weight of a load. This responsibility is crucial for maintaining standard practices in weight verification and for ensuring that the weighing process is fair and consistent.

The other options present different scenarios that do not align with the established practices for determining average tare weights. Average tare weights are not determined on a per-load basis at certification, nor are they limited to single-use for one load only. Additionally, while regulatory bodies such as the Department of Food and Agriculture may set broader guidelines and standards, they typically do not engage directly in calculating tare weights for individual loads. Thus, the correct choice highlights the appropriate authority responsible for this aspect of weight verification.
