The latest tender, which followed a regular weekly tender that closed on Friday, was to meet demand from Japanese millers.
Japan, the world's sixth-biggest wheat importer, keeps a tight grip on imports of the country's second most important staple after rice and buys the majority of the grain for milling via tenders typically issued three times a month.
But the country has been ramping up its purchases of Canadian wheat used for making bread and noodles this year in a move to offset the possibility of extended shipping delays from Canada due to the bumper crop and winter weather.
