A typographic error in information supplied to Green Markets prior to publication misstated the export duty for Chinese DAP and MAP. The correct export rate is 5 percent, not 2 percent as earlier reported.
Also, missing from the initial data was a change in the export window for DAP and MAP. The Chinese government added two weeks on each end of the previous export window. The lower 5 percent duty will be charged on DAP and MAP May 16 through Oct. 15. The previous window was June through September.
Green Markets regrets the error. See the forthcoming Special Edition of Green Markets to be on the website Dec. 28, 2012 for further discussion on this issue.
