Definition of goods narrowed to specified fuels - Form C eligibility and 2% inter state concession limited accordingly. Amendment confines goods under the Central Sales Tax Act to six specified fuel and related items; concessional 2% inter state tax under section 8 with Form C applies only to those goods and permitted uses. Post GST repeal of VAT for other items cancelled registrations for dealers of non specified goods, and therefore Form C cannot be issued where the acquisition is for manufacture or use outside the defined six item scope.
