 Although there is a slight export trade in ferromanganese the quantity manufactured
in tHe United States is supplemented by imports. Ferromanganese imported
for consumption in 1932 included 27 tons containing not over 1 percent carbon.
Imports of ferromanganese for consumption in the United States and exports
of ferromanganese and spiegeleisen, 1928—32, are given in the following
table.
