Separate excise duty on machined forged parts upheld, but extended recovery period failed for lack of suppression or intent to evade.

Machined and polished railway wheels, tyres and axles, after forging, were treated as separately identifiable finished goods and therefore attracted duty under the residuary tariff item in addition to duty under the forged-products tariff entry. The court also applied the normal six-month limitation period for duty recovery, holding that the extended period was unavailable because the record showed disclosure of the classification position, departmental acceptance of classification lists, and no proof of fraud, suppression, wilful misstatement, or intent to evade duty. As a result, the demand was upheld on classification but curtailed for the period beyond limitation.

Issues: (i) Whether machined and polished wheels, tyres and axles, after being forged, were separately exigible to excise duty under the residuary tariff item in addition to the duty already chargeable under the forged-products tariff item; (ii) Whether recovery of duty and differential duty for the period from March 1975 to 15 November 1980 was barred by limitation under the excise law.

Issue (i): Whether machined and polished wheels, tyres and axles, after being forged, were separately exigible to excise duty under the residuary tariff item in addition to the duty already chargeable under the forged-products tariff item.

Analysis: Forged steel products fell within the relevant tariff entry, but the process did not end with forging. The goods were further subjected to machining and polishing before supply, and the record showed that such processing was not merely nominal. The later tariff structure was treated as a significant indicator that forged rough shapes and finished railway parts were distinct commodities in trade and classification. On that basis, machined and polished wheels, tyres and axles were regarded as separately identifiable goods, though still falling within the forged-products entry for the earlier stage.

Conclusion: The machined and polished wheels, tyres and axles were held exigible to duty under the residuary tariff item as separate goods, in addition to duty under the forged-products tariff item.

Issue (ii): Whether recovery of duty and differential duty for the period from March 1975 to 15 November 1980 was barred by limitation under the excise law.

Analysis: The normal limitation period was six months, with an extended period available only on proof of fraud, collusion, wilful mis-statement, suppression of facts, or contravention with intent to evade duty. The facts showed long-standing disclosure of the classification position, acceptance of classification lists by the department, and a bona fide belief that the goods remained assessable only as forged items. Those circumstances negatived fraud, suppression, wilful mis-statement, and intent to evade. Consequently, the extended period could not be invoked, and recovery was confined to the ordinary limitation period preceding notice.

Conclusion: Recovery for the period beyond six months was held barred, and the demand was sustained only for the limited period within limitation.

Final Conclusion: The petition succeeded only in part: the duty demand was upheld on the substantive classification issue, but the demand was curtailed on limitation, with relief granted for the period outside the permissible recovery window.

Ratio Decidendi: Where a forged article is subsequently transformed by substantial machining and polishing into a distinct, identifiable finished product, it may attract separate excise duty as a new commodity; however, the extended limitation period for duty recovery applies only on proof of fraud, suppression, wilful mis-statement, or intent to evade duty.
