Private exporters reported the sale of 110,000 tonnes of corn to Japan for the 2004/05 marketing year, the US Agriculture Department said on Friday. The marketing year for corn began on Sept 1. US exporters must report any US or optional origin export sales activity of at least 100,000 tonnes - except 20,000 tonnes or more for soybean oil - made in one day to a single destination by the following business day. Sales of smaller quantities must be reported weekly.
