When must a weigh master issue a weigh master certificate?

A weigh master must issue a weigh master certificate whenever payment for a commodity is based on a documented weight. This requirement ensures that the weight measurement used to determine the payment is accurate and verifiable. The certificate provides a formal record of the weight, which is crucial for both buyers and sellers in maintaining fairness and transparency in transactions. Documented weights are essential for establishing the value of the commodity being exchanged, as they serve as an official acknowledgment of the quantity involved.

In contrast, while sales and testing of commodity quality are important processes, they do not directly relate to the necessity of issuing a weigh master certificate in the context of payment. Additionally, limiting the issuance of the certificate to only upon customer request would undermine the role of the weigh master in ensuring that all transactions based on weight are properly documented and transparent.
