The country exported some 820,000 tonnes of corn in the period, or an average of 81,900 tonnes over 10 working days, representing a 65 percent rise in daily volumes from the comparable period of last year.
Brazil has became an increasingly important corn exporter, especially in the second half of the year, with so-called winter corn, which is planted after soybeans are harvested. Bolstered by a bumper harvest, this season Brazil is poised to export near-record volumes, adding to competition with Argentina and the United States in global markets.
An estimated 33 percent to 36 percent of Brazil's winter corn had been harvested by the end of last week, according to independent consultants Safras & Mercado and AgRural.
Grains exporter association Anec projects the current crop cycle to yield 30 million tonnes of exports, on par with two seasons ago, when the country registered record sales abroad.
The government has been slightly more conservative, estimating 28 million tonnes of exports from this harvest.
