WASHINGTON — U.S. imports of sugarcane ethanol from Brazil fell by 40 percent last year, to 242 million gallons, Today in Energy reported.

Because Brazil is the largest source of ethanol imports into the U.S., this drop led the U.S. to be a net exporter of the product for the year.

Export volumes of corn-based ethanol to Brazil declined, but were more than offset by higher export volumes to Canada and a number of other countries.

Although the net level has varied from month to month, since 2011 the U.S. has both imported ethanol from and exported ethanol to Brazil.
