Limitation and manufacture under excise law: open processing and mere insulation did not justify extended demand or fresh duty.

The extended period of limitation under the excise law could not be invoked for the pressure vessels because the record showed open processing, delivery challans, and maintained papers, with no finding of fraud, suppression, wilful misstatement, or intent to evade duty; the demand beyond six months was therefore time-barred. External insulation of already fabricated pressure vessels did not amount to manufacture, as it only improved efficiency without changing the basic character of the goods; reassessment under Tariff Entry 73.11 was not justified. The uncontested demand on fibre reinforced plastic sheets was upheld, and the limited penalty was sustained.

Issues: (i) Whether the extended period of limitation under the proviso to Section 11A could be invoked for the demand on pressure vessels. (ii) Whether external insulation of already fabricated pressure vessels amounted to manufacture so as to attract duty again under Tariff Entry 73.11. (iii) Whether the uncontested demand on fibre reinforced plastic sheets and the connected penalty were sustainable.

Issue (i): Whether the extended period of limitation under the proviso to Section 11A could be invoked for the demand on pressure vessels.

Analysis: The vessels had been purchased as compliant storage vessels for compressed or liquefied gas, supported by the prescribed certificates and inspection under the Static and Mobile Pressure Vessels (Unfired) Rules, 1981. The record also showed that the insulation work was carried out openly, the removals were under delivery challans, and relevant papers were maintained. In the absence of a finding of fraud, wilful misstatement, suppression of facts, or intent to evade duty, the extended limitation could not be applied.

Conclusion: The invocation of the extended period was illegal and the demand on the pressure vessels beyond six months was barred by limitation, in favour of the assessee.

Issue (ii): Whether external insulation of already fabricated pressure vessels amounted to manufacture so as to attract duty again under Tariff Entry 73.11.

Analysis: The vessels had already acquired the character of containers for compressed or liquefied gas when received by the assessee. External insulation improved efficiency but did not alter the basic character of the goods, and there was nothing in the definition of manufacture or in Tariff Entry 73.11 to treat such insulation as a fresh manufacture. The earlier fabricated vessels therefore could not be reassessed merely because insulation was added.

Conclusion: External insulation did not amount to manufacture and the reassessment of the pressure vessels was not justified, in favour of the assessee.

Issue (iii): Whether the uncontested demand on fibre reinforced plastic sheets and the connected penalty were sustainable.

Analysis: The demand relating to fibre reinforced plastic sheets was not contested. The materials were captively consumed without payment of duty and without following the prescribed excise formalities, which justified a limited penalty.

Conclusion: The demand on fibre reinforced plastic sheets was upheld and the penalty of Rs. 2,000 was sustained, against the assessee.

Final Conclusion: The demand on the pressure vessels failed on limitation and on the nature of the process involved, while the uncontested demand on fibre reinforced plastic sheets and the limited penalty were maintained; the matter on the merits of the pressure vessels was remitted for fresh examination.

Ratio Decidendi: The extended period of limitation under the excise law can be invoked only when the adjudicating authority records a finding of fraud, suppression, wilful misstatement, or other conduct showing intent to evade duty, and a process that merely improves an already existing excisable article does not by itself amount to manufacture.
