Arm's-length valuation and excise exemption turned on contractual control, tariff classification, and exclusion of post-manufacturing costs.

In excise valuation, an agreement is not treated as arm's length where the cumulative contractual and commercial circumstances show substantial control, financial support, technical assistance, restrictions on expansion, and branded supply under one party's influence; the finding that the petitioners' arrangement with Bata Shoe Co. was not independent was upheld. An exemption notification confined to articles made of plastics under Tariff Item 15A(2) could not be extended to plastic footwear falling under Tariff Item 36, so the exemption claim failed for that period. For later notifications, exemption eligibility for footwear costing less than Rs. 5/- had to be tested on wholesale price after excluding post-manufacturing expenses, and the assessable value was remitted for fresh determination on that basis.

Issues: (i) Whether the agreement between the petitioners and Bata Shoe Co. was at arm's length for the purpose of assessment under the excise law; (ii) whether the 1 March 1964 exemption notification applied to plastic footwear falling under Tariff Item 36; (iii) whether the assessable value had to be worked out after excluding post-manufacturing costs so as to determine entitlement to exemption for footwear costing less than Rs. 5/-.

Issue (i): Whether the agreement between the petitioners and Bata Shoe Co. was at arm's length for the purpose of assessment under the excise law.

Analysis: The relevant question was not whether any single clause, viewed in isolation, suggested independence, but whether the agreement had to be judged on the cumulative effect of all its terms and surrounding circumstances. The arrangement showed substantial control and financial support by Bata Shoe Co., including technical assistance, interest-free advances, restrictions on expansion and installation of machinery, and supply of the entire production under Bata's brand name. On an overall assessment, the agreement did not reflect dealings between two independent units.

Conclusion: The agreement was not at arm's length, and the finding against the petitioners was upheld.

Issue (ii): Whether the 1 March 1964 exemption notification applied to plastic footwear falling under Tariff Item 36.

Analysis: The notification exempted articles made of plastics falling under Item 15A(2) of the First Schedule. Plastic footwear manufactured by the petitioners fell under Tariff Item 36, not under Item 15A(2). The exemption was therefore confined to a different class of goods and could not be extended to footwear covered by Item 36.

Conclusion: The exemption notification did not apply to the petitioners' plastic footwear, and the claim for exemption for the relevant period failed.

Issue (iii): Whether the assessable value had to be worked out after excluding post-manufacturing costs so as to determine entitlement to exemption for footwear costing less than Rs. 5/-.

Analysis: The later notifications granted exemption to footwear costing less than Rs. 5/- from the relevant date, and entitlement had to be tested on the basis of the wholesale price after excluding post-manufacturing expenses. The authorities had to recompute assessable value on that basis before deciding whether the goods qualified for exemption. That exercise required fresh factual determination by the assessing authority.

Conclusion: The petitioners were entitled to reconsideration on this aspect, and the matter had to be remitted for fresh determination of assessable value after exclusion of post-manufacturing costs.

Final Conclusion: The challenge failed on the arm's-length and 1964-notification issues, but succeeded to the limited extent that the assessable value had to be recalculated after excluding post-manufacturing costs for deciding exemption eligibility under the later notifications.

Ratio Decidendi: In excise valuation, the agreement and the assessable value must be judged on the cumulative effect of all relevant contractual and commercial circumstances, and exemption eligibility must be determined on the basis of the correct assessable value after excluding non-manufacturing costs where the scheme so requires.
