Job work valuation includes retained scrap value where it affects conversion charges and supports extended limitation.

In job work valuation of motor vehicle parts, scrap generated from the customer's raw material and retained by the job worker was held includible in assessable value where it formed an additional element affecting the conversion charges. The analysis applied the principle that the full raw material value and conversion element must be considered, and that separate realisation of scrap or payment of excise on scrap does not by itself exclude it from valuation. On limitation, the extended period was available because the assessee did not file price declarations, did not disclose the job-work arrangement, and used invoices that understated the correct assessable value.

Issues: (i) Whether the value of scrap retained and sold by the job worker is includible in the assessable value of motor vehicle parts manufactured on job work basis; (ii) Whether the demand is barred by limitation.

Issue (i): Whether the value of scrap retained and sold by the job worker is includible in the assessable value of motor vehicle parts manufactured on job work basis.

Analysis: The valuation question was governed by the principle that, in job work manufacture, the value of scrap generated out of the customer's raw material can operate as an additional element of consideration where it reduces the conversion charges recovered for the work done. The later Supreme Court decision reaffirmed that the full quantity of raw material and the conversion element must be taken into account, and that scrap value cannot be excluded merely because scrap is separately realized or excise is paid on it. Applying that rule, the retained scrap value had to form part of the assessable value.

Conclusion: The issue was decided in favour of Revenue and against the assessee.

Issue (ii): Whether the demand is barred by limitation.

Analysis: The relevant period was one in which the law stood against the assessee on scrap valuation. The assessee did not file price declarations, did not disclose the job-work arrangement to the department, and used invoices showing sale to independent customers instead of the correct assessable value. These facts justified invocation of the extended period, and the plea of bona fide belief did not avail the assessee.

Conclusion: The demand was not barred by limitation and the extended period was available to the department.

Final Conclusion: The duty demand was sustained, the company's penalty was substantially reduced, the penalties on the officers were set aside, and the Revenue's plea for enhancement of penalty was rejected.

Ratio Decidendi: In job work valuation, scrap value generated from the customer's raw material is includible in assessable value where it constitutes an additional element affecting conversion charges, and deliberate non-disclosure of the correct valuation facts supports invocation of the extended limitation period.
