“Bulk grains, feeds and feedstuffs”, as used in this section and section 43-21, means all such substances sold or offered for sale in loose form and delivered to or from a vehicle, truck, compartment or container in quantities of one hundred pounds or more. Quantity determination in the sale of bulk grains, feeds and feedstuffs shall be by avoirdupois weight. All bulk grains, feeds and feedstuffs sold or offered for sale in this state shall be sold or offered for sale in accordance with the provisions of this section and section 43-21, except that the Commissioner of Consumer Protection may upon request approve in writing the use of other methods of determining the true net weight of the contents of the container, compartment, truck or vehicle used to transport such bulk grain, feeds or feedstuffs. No person shall deliver grains, feeds or feedstuffs in bulk without first having such grains, feeds or feedstuffs weighed by a public weigher on stationary scales, suitable for the weighing of bulk grains, feeds or feedstuffs, which have been tested and scaled by an authorized sealer or inspector of weights and measures. Each vehicle, truck, compartment or container of bulk grains, feeds and feedstuffs while in transit delivery shall be accompanied by a delivery ticket and a duplicate original thereof, on which shall be distinctly expressed in ink or other indelible substance (a) in pounds avoirdupois the gross and tare weights of the vehicle, truck, compartment or container; (b) the net weight of bulk grains, feeds and feedstuffs contained in such vehicle, truck, compartment or container; (c) the name and address of the seller; (d) the name and address of the buyer; (e) the signature and license number of the public weigher; and (f) the date of the weighing. One of such duplicate delivery tickets shall be surrendered, upon demand, to any sealer or inspector of weights and measures for his inspection; and such ticket or, when such sealer desires to retain one of the duplicate tickets, a weight slip issued and signed and dated by the sealer or inspector shall be delivered to the buyer or his agent or representative at the time of delivery of such grains, feeds or feedstuffs, and the other duplicate ticket shall be retained by the seller for a period of one year, during which time it shall be subject to inspection by a sealer or inspector of weights and measures. If the buyer takes such grains, feeds or feedstuffs from the vendor’s place of business, a delivery ticket in the form required by this section, signed by a licensed public weigher, shall be given to the buyer or his agent at the time of delivery. No person shall sell or deliver, or attempt or offer to sell or deliver, less than the amount of such grains, feeds or feedstuffs represented by the delivery tickets therefor, provided a tolerance of five pounds to the ton shall be allowed. No public weigher shall weigh grains, feeds or feedstuffs delivered to a vehicle, truck, compartment or container for transportation purposes and sign a delivery ticket therefor unless he has first weighed the vehicle, truck, compartment or container, empty, on the same scale, in order to determine the tare weight and the true net weight of the contents of the vehicle, truck, compartment or container.
