Infrastructure Cess explicitly inserted into central excise non tariff notifications, clarifying its treatment in export linked duty relief. Amendments add Infrastructure Cess, leviable under sub-clause (1) of clause 159 of the Finance Bill, 2016 and given force of law by provisional declaration, into the explanatory provisions of Notifications No. 42/2001-CE(NT), No. 43/2001-CE(NT) and No. 19/2004-CE(NT), and substitute the Explanation in Notification No. 21/2004-CE(NT) to list Secondary and Higher Education Cess and Infrastructure Cess, thereby ensuring the Infrastructure Cess is expressly recognised alongside other cesses in non-tariff duty relief contexts.
