Coal-ash, industrial exemption, and unclassified goods treatment under sales tax law clarified for manufacturing inputs and residues.

Coal-ash was treated as a distinct commercial commodity from coal because the coal entry covered coal including coke in all its forms, not the burnt residue left after use as fuel; the India Carbon Ltd. decision was held inapplicable on that basis. The exemption for products of specified industrial units did not extend to coal-ash because it was only residue generated in the manufacturing process and not one of the unit's manufactured products. Debarked eucalyptus and casuarina wood purchased from unregistered dealers were assessed as unclassified goods under section 6-A since there was no proof that the goods were firewood, and the factual finding that they were raw material for manufacture was accepted.

Issues: (i) Whether coal and coal-ash are the same commodity or different commodities for taxation under the Andhra Pradesh General Sales Tax Act, 1957, and whether the decision in India Carbon Ltd. applied; (ii) whether coal-ash is a product of the industrial unit eligible for exemption under G.O. Ms. No. 606 dated 09.04.1981; (iii) whether eucalyptus and casuarina wood purchased from unregistered dealers were rightly assessed as unclassified goods under section 6-A of the Andhra Pradesh General Sales Tax Act, 1957.

Issue (i): Whether coal and coal-ash are the same commodity or different commodities for taxation under the Andhra Pradesh General Sales Tax Act, 1957, and whether the decision in India Carbon Ltd. applied.

Analysis: Coal-ash was treated as the burnt residual product left after coal was used as fuel. The entry for coal in the Third Schedule referred to coal including coke in all its forms, but it did not extend to coal-ash. The Court relied on earlier authority distinguishing cinders from coal in popular and commercial sense and on the principle that a derived commodity cannot be introduced into the taxing entry merely because it comes from the primary commodity. The Supreme Court decision in India Carbon Ltd. was held inapplicable because it dealt with petroleum coke and the scope of coal including coke in all its forms, not with coal and coal-ash.

Conclusion: Coal and coal-ash are commercially different commodities, coal-ash is taxable as a first sale in the hands of the petitioner, and the objection based on India Carbon Ltd. fails.

Issue (ii): Whether coal-ash is a product of the industrial unit eligible for exemption under G.O. Ms. No. 606 dated 09.04.1981.

Analysis: The exemption applied to sale of products of specified industrial units. The petitioner's principal manufacture was paper and paperboards, while coal-ash was only residue generated after coal was burnt as fuel in the manufacturing process. It was not part of the unit's manufactured products and did not answer the description of a product for the purpose of the exemption notification.

Conclusion: Coal-ash is not a product of the industrial unit and the claim for exemption under G.O. Ms. No. 606 fails.

Issue (iii): Whether eucalyptus and casuarina wood purchased from unregistered dealers were rightly assessed as unclassified goods under section 6-A of the Andhra Pradesh General Sales Tax Act, 1957.

Analysis: The invoices described the goods as debarked eucalyptus wood and casuarina wood, and no material established that they were firewood. The Court accepted the Tribunal's factual finding that the purchases were for raw material in the manufacturing activity and held that, in the absence of proof that the goods were firewood, the department was justified in treating them as unclassified goods and levying tax accordingly under section 6-A.

Conclusion: The assessment of the wood as unclassified goods under section 6-A is upheld.

Final Conclusion: All the substantive questions were decided against the petitioner, the tax treatment adopted by the revenue authorities was sustained, and the revision cases failed.

Ratio Decidendi: A derived or residual item is not taxable as the primary commodity unless the taxing entry expressly includes it, and an industrial exemption for the unit's products does not extend to a mere residue generated in the course of manufacture.
