Increase in import duty on areca nuts under the Customs Tariff Act enacted, amending the tariff entry and invoking emergency powers. An increase in import duty is imposed on areca nuts under Chapter 8 by amending the First Schedule of the Customs Tariff Act: the Central Government, invoking its statutory emergency power, directs substitution of the tariff entry applicable to the relevant subheading in Section II of Chapter 8, thereby changing the tariff treatment of imported areca nuts.
