Factory-use exemption for job-worked tractor parts applies on proven end use, while absent suppression bars extended limitation.

Machined tractor parts returned by a job-worker qualified for exemption where they were used within the recipient manufacturer's factory to produce tractors under Heading 8701. The factory-use condition required proof of the prescribed end use, not that the inputs or castings originated in that factory; treating the same job-work consideration as subject to both service tax and central excise duty was impermissible. The extended limitation period was unavailable because the assessee was service-tax registered, paid tax on job-work charges, filed returns regularly, and no suppression of material facts with intent to evade duty was established. The duty demands therefore failed on exemption eligibility and limitation.

Issues: (i) Whether machined tractor parts returned by a job-worker to principal manufacturers were eligible for exemption when used within the recipient's factory for manufacture of tractors; (ii) Whether the extended period of limitation could be invoked for demanding central excise duty.

Issue (i): Whether machined tractor parts returned by a job-worker to principal manufacturers were eligible for exemption when used within the recipient's factory for manufacture of tractors.

Analysis: The relevant exemption entries required that the goods be parts, be used within the factory of production, and be used in manufacture of tractors falling under Heading 8701. The parts satisfied these conditions. The expression concerning use within the factory did not require that the inputs or castings must have originated or been generated in that factory. The job-work had consistently been treated as a taxable service and service tax was paid on the job charges without departmental objection. Levying central excise duty additionally on the same work and consideration was impermissible.

Conclusion: The exemption was available to the assessee; this issue was decided in favour of the assessee.

Issue (ii): Whether the extended period of limitation could be invoked for demanding central excise duty.

Analysis: The assessee was registered for service tax, paid tax on the job-work charges, and regularly filed returns. In the absence of suppression of material facts with intent to evade duty, the extended limitation period was unavailable.

Conclusion: The extended period could not be invoked; this issue was decided in favour of the assessee.

Final Conclusion: The duty demands failed both on substantive eligibility for exemption and on limitation.

Ratio Decidendi: An exemption conditional on use of parts within the factory of production is available where the prescribed end use is established, without requiring that the inputs originate in that factory; extended limitation requires suppression with intent to evade duty.
