the President or other member of the executive branch of the Federal Government causes the export of any agricultural commodity to any country or area of the world to be suspended or restricted for reasons of national security or foreign policy under the Export Administration Act of 1979 (50 U.S.C. App. 2401 et seq.) 1 or under any other provision of law;

such suspension or restriction of the export of such agricultural commodity is imposed other than in connection with a suspension or restriction of all exports from the United States to such country or area of the world; and

sales of such agricultural commodity for export from the United States to such country or area of the world during the year preceding the year in which the suspension or restriction is imposed exceeds 3 percent of the total sales of such commodity for export from the United States to all foreign countries during the year preceding the year in which the suspension or restriction is in effect;

in the case of other agricultural commodities for which price support is authorized for producers under the Agricultural Act of 1949 (7 U.S.C. 1421 et seq.), by multiplying the amount by which the average market price per unit of such commodity received by the producers during the 60-day period immediately following the date of the imposition of the suspension or restriction is less than 100 percent of the parity price for such commodity, as determined by the Secretary on the date of the imposition of the suspension or restriction, by the quantity of such commodity sold by the producer during the period that the suspension or restriction is in effect.
