During any marketing year for which a wheat marketing allocation program is in effect,
(ii) all persons exporting wheat shall, prior to such export, acquire export marketing certificates equivalent to the number of bushels so exported. The cost of the export marketing certificates per bushel to the exporter shall be that amount determined by the Secretary on a daily basis which would make United States wheat and wheat flour generally competitive in the world market, avoid disruption of world market prices, and fulfill the international obligations of the United States. The Secretary may exempt from the requirements of this subsection wheat exported for
donation abroad and other noncommercial exports of wheat, wheat processed for use on the farm where grown, wheat produced by a State or agency thereof and processed for use by the State or agency thereof, wheat processed for
donation, and wheat processed for uses determined by the Secretary to be noncommercial. Such exemptions may be made applicable with respect to any wheat processed or exported beginning July 1, 1964. There shall be exempt from the requirements of this subsection beverage distilled from wheat prior to July 1, 1964. A beverage distilled from wheat after July 1, 1964, shall be deemed to be removed for sale or consumption at the time it is placed in barrels for aging except that upon the giving of a bond as prescribed by the Secretary, the purchase of and payment for such marketing certificates as may be required may be deferred until such beverage is bottled for sale. Wheat shipped to a Canadian port for storage in bond, or storage under a similar arrangement, and subsequent exportation, shall be deemed to have been exported for purposes of this subsection when it is exported from the Canadian port. Marketing certificates shall be valid to cover only sales or removals for sale or consumption or exportations made during the marketing year with respect to which they are issued, and after being once used to cover a sale or removal for sale or consumption or export of a food product or an export of wheat shall be void and shall be disposed of in accordance with regulations prescribed by the Secretary. Notwithstanding the foregoing provisions hereof, the Secretary may require marketing certificates issued for any marketing year to be acquired to cover sales, removals, or exportations made on or after the date during the calendar year in which wheat harvested in such calendar year begins to be marketed as determined by the Secretary even though such wheat is marketed prior to the beginning of the marketing year, and marketing certificates for such marketing year shall be valid to cover sales, removals, or exportations made on or after the date so determined by the Secretary. Whenever the face value per bushel of domestic marketing certificates for a marketing year is different from the face value of domestic marketing certificates for the preceding marketing year, the Secretary may require marketing certificates issued for the preceding marketing year to be acquired to cover all wheat processed into food products during such preceding marketing year even though the food product may be marketed or removed for sale or consumption after the end of the marketing year.
