Missouri Revised Statutes Title XVII. Agriculture and Animals § 265.500. Grain samples--sample sealed, when--state inspection, when--federal inspection, when--cost, how paid

1. Whenever the value of grain is established by analysis of a drawn sample, the seller of the grain may request in writing at the time the sample is taken that the sample be divided into two equal parts, one of which shall be sealed in an airtight container.

2. Upon written request, the buyer must keep the sealed sample for a twenty-four hour period, except that weekends or holidays shall not be included in the mandatory twenty-four hour period. During the designated period the seller may cause the sample to be delivered to an official Missouri grain inspection office by the buyer. The seller shall bear all costs of securing the official test and the results of the official test shall be the basis of payment. If either the seller or buyer is  1 dissatisfied with the results of the test, an official federal test may be requested by either the buyer or seller at the cost of the person requesting the test and such findings shall be binding on all parties thereto.
