Central Excise input use and limitation: tow in fibre manufacture treated as utilised, while extended period and penalty failed.

Tow used in manufacturing polyester staple fibre was treated as utilised in manufacture where waste was a technological inevitability under the third proviso to Rule 9(1) of the Central Excise Rules, and duty was not sustainable to the extent the fibre was cleared for export or under exemption. The extended period of limitation and penalty were also held unsustainable because the factory remained under departmental physical control, earlier proceedings had already disclosed the tow usage, and the department had knowledge of the relevant facts. The duty demand and consequential penalty were therefore set aside.

Issues: (i) Whether duty was payable on tow used in the manufacture of polyester staple fibre when the fibre was cleared without duty for export or under exemption. (ii) Whether the extended period of limitation and penalty were sustainable.

Issue (i): Whether duty was payable on tow used in the manufacture of polyester staple fibre when the fibre was cleared without duty for export or under exemption.

Analysis: The third proviso to Rule 9(1) of the Central Excise Rules applies where goods are consumed or utilised as raw material or component parts in the manufacture of another commodity. Waste arising in the course of manufacture was held to be a technological inevitability, and the tow used in producing the fibre was treated as having been utilised in the manufacture of the fibre. Duty was not, however, payable where the fibre itself was removed for export or otherwise in the exempted manner noted in the order.

Conclusion: The demand of duty on tow was not sustainable to the extent it related to such manufacture, and the issue was decided in favour of the assessee.

Issue (ii): Whether the extended period of limitation and penalty were sustainable.

Analysis: The factory was under physical control of the department, earlier proceedings had already shown departmental knowledge of the tow utilisation, and the prior notice evidenced awareness of the very facts on which the later demand was based. On those facts, suppression or other grounds necessary for invoking the extended period were not made out, and the penalty could not survive.

Conclusion: The extended period of limitation and the penalty were not sustainable.

Final Conclusion: The duty demand and consequential penalty were set aside, resulting in complete relief to the assessee.

Ratio Decidendi: Where the manufacturing process necessarily generates waste and the department already has knowledge of the relevant use of inputs, the input is treated as utilised in manufacture for the purpose of the excise rule, and the extended limitation cannot be invoked absent suppression or equivalent conduct.
