RABAT (Reuters) - Morocco has slashed it soft wheat import tariffs to 90 percent from 135 percent and durum wheat to 80 percent from 170 percent, the country's state grains agency ONICL said on Monday. "Import tariffs for soft wheat are at 90 percent as from January 1, 2010 and at 80 percent for durum wheat, also as from January 1, 2010," ONICL said in a statement. Morocco had raised import tariffs to 135 percent for soft wheat and 170 percent for durum wheat last year to shield its domestic farmers against foreign competition. It had a record cereals harvest of 10.2 million tonnes last year -- 4.3 million tonnes of soft wheat and 2.03 million tonnes of durum wheat and the rest barley. As a result, its combined imports of soft and durum wheat slumped 42 percent to 2.36 million tonnes last year, according to government figures. Early last month, the state forecasting High Planning Commission had said it expected Morocco's cereals harvest to fall to at least 7 million tonnes this year versus the previous harvest. ONICL also said on Monday that import tariffs for barley and corn were 35 percent and 17 percent respectively as from January 1, but it gave no comparative figures. Morocco's barley and corn imports fell 55.5 percent and 29.9 percent respectively last year compared with the previous year, according to government data which did not give the corresponding volumes.
