Exemption for Chapter 90 goods extended to manufacture of equipment using non conventional energy, aligning conditions with machinery. Amendment broadens Notification No. 123/87-Cus by adding goods falling within Chapter 90 to the class of inputs exempt when imported for manufacture of equipment that functions with the aid of non-conventional forms of energy, and replaces 'said machinery' with 'said machinery or goods' in conditions (i) and (ii) so that the exemption's conditions apply to both machinery and Chapter 90 goods.
