South Africa imported the white variety from the U.S. for the first time in 12 years as the worst drought in more than a century hurt local output. The country imported 1,330 metric tons of the white type from the U.S. in the week ended April 15, Pretoria-based South African Grain Information Service said in a statement on its website Tuesday. It last brought in U.S. corn in the season ended April 2004, when it imported 32,937 tons.
