Periodic sample test results govern excisability until the next sample where no manufacturing change is proved

Periodic sample test reports for nylon filament yarn showing denierage above the exemption limit were treated as governing the intervening period until the next sample, because the assessee did not prove any change in manufacturing process or product characteristics after sampling. The duty demand was therefore sustained on that basis. For valuation, abatement from the sale price was recognised under excise law, and Modvat credit on chips was allowed to the extent duty had been paid under protest and remained open to adjustment. A further claim for additional exclusion based on FIFO and alleged deemed exports was rejected for lack of correlation.

Issues: (i) whether the chemical test reports on samples of nylon filament yarn could be applied to determine dutiability for the entire period until the next sample was drawn; and (ii) whether the assessee was entitled to abatement of duty from sale price and Modvat credit on inputs.

Issue (i): whether the chemical test reports on samples of nylon filament yarn could be applied to determine dutiability for the entire period until the next sample was drawn.

Analysis: The sample results from the Chemical Examiner, the Chief Chemist and the National Test House were concurrent and all showed denierage above the exemption limit. The assessee failed to establish that any change in process parameters had actually been made after sampling so as to produce a different product thereafter. In such circumstances, the earlier line of authority holding that a sample drawn on one date governs the production until the next sample was taken was followed.

Conclusion: The test reports were rightly applied for the entire intervening period, and the duty demand on that basis was sustained.

Issue (ii): whether the assessee was entitled to abatement of duty from sale price and Modvat credit on inputs.

Analysis: The yarn removed for export had already been excluded by the lower authorities. However, the assessee was entitled to abatement of duty from the sale price in determining assessable value under the excise law. The claim for Modvat credit on chips was also accepted to the extent the duty payment on chips stood under protest and remained legally open for adjustment in accordance with law. The plea for a further equitable exclusion based on FIFO and alleged deemed exports was not accepted for want of correlation.

Conclusion: Abatement from sale price and Modvat credit on chips were allowed, while the remaining claim for additional exclusion was rejected.

Final Conclusion: The demand of duty on the yarn was maintained in principle, but the assessment was required to be recomputed by extending the statutory abatements and credit reliefs granted to the assessee.

Ratio Decidendi: Where periodic sample tests of excisable goods uniformly show non-eligibility for exemption and the assessee fails to prove any intervening change in manufacture, the test result applies until the next sample is drawn.
