Russia will be increasing its export duties on wheat, meslin, barley, and corn from September 13 to 19, 2023. The increased duties will be 4,493.7 rubles per ton for wheat and meslin, 931.7 rubles per ton for barley, and 2,465.2 rubles per ton for corn. This decision comes after concerns about potential disruptions to field work due to a shortage of fuel and lubricants.
