USDA SAYS WHEAT PURCHASED FROM FOREIGN SELLERS The U.S. Agriculture Department said private U.S. exporters reported purchases from foreign sellers of 120,000 tonnes of wheat for delivery to unknown destinations. The wheat, consisting of 60,000 tonnes of hard red winter and 60,000 tones of soft red winter, is for delivery during the 1987/88 season, which begins June 1. A purchase from a foreign seller is a transaction in which a U.S. exporter contracts to buy U.S.-produced commodities from a foreign firm, the department said.
