All of the sales were for deliver this marketing year. They were 20.000 tonnes of U.S. soyoil to China, 120.000 tonnes of U.S. corn to unknown destinations and 110.000 tonnes of soybeans to unknown destinations. The 2010/11 marketing year for corn and soybeans ends Aug. 31 and for soyoil on Sept. 30. By law, exporters must report promptly the sale of 100.000 tonnes or more of a commodity, except for 20.000 tonnes or more of soyoil, to the same destination in one day. But it sometimes can take a couple of days for the identity of a buyer to become known. Sales of smaller amounts are reported weekly.
