Extended limitation, alkaloid classification and related-party valuation fail where disclosure and statutory evidentiary requirements are unmet.

Extended limitation for central excise recovery requires suppression or misstatement; consistent disclosure of Nicotine Sulphate's manufacture and Chapter 29 classification in ER-1 returns does not support its invocation. Nicotine Sulphate is described as a vegetable alkaloid derivative classifiable under CTH 29399900, as the Chapter 29 exception for alkaloids applies despite the general requirement of separate chemical definition. The analysis also questions reliance on delayed third-party sample testing and classification opinions by chemical examiners. Related-party valuation requires evidence meeting the statutory test; a common individual's roles in the supplier and purchaser alone do not establish that relationship or justify cost-based valuation.

Issues: (i) Whether recovery of central excise duty by invocation of the extended limitation period was sustainable; (ii) Whether Nicotine Sulphate was classifiable under CTH 24039990 or CTH 29399900; (iii) Whether the manufacturer and purchaser were related parties for valuation of the goods supplied to the purchaser.

Issue (i): Whether recovery of central excise duty by invocation of the extended limitation period was sustainable.

Analysis: The manufacturer had informed the department of manufacture and classification of Nicotine Sulphate under Chapter 29 and had consistently disclosed the disputed classification in monthly ER-1 returns. The disclosed material did not support an allegation of suppression or misstatement necessary to invoke the extended period.

Conclusion: The demand for June 2015 to June 2017 issued by invoking the extended limitation period was barred by limitation, in favour of the assessee.

Issue (ii): Whether Nicotine Sulphate was classifiable under CTH 24039990 or CTH 29399900.

Analysis: The manufacturing process showed that the product was a vegetable alkaloid. Heading 29.39 covers alkaloids and their derivatives, and the Chapter 29 restriction concerning separately chemically defined compounds did not exclude this product because alkaloids are an identified exception under the HSN general notes. The report relied on by Revenue concerned a sample drawn from a third-party premises without the manufacturer's representative, tested more than a year after drawal contrary to the prescribed sampling standard, and included a classification opinion beyond the chemical examiner's analytical role. Factory samples tested subsequently described the product as an aqueous solution of Nicotine Sulphate and an organic chemical.

Conclusion: Nicotine Sulphate was correctly classifiable under CTH 29399900 and not under CTH 24039990; the consequential duty, interest and penalty were unsustainable, in favour of the assessee.

Issue (iii): Whether the manufacturer and purchaser were related parties for valuation of the goods supplied to the purchaser.

Analysis: The allegation of related-party status rested on one individual being a partner of the manufacturer and managing director of the purchaser. No supporting evidence established that the entities satisfied the statutory requirements of related persons. The valuation demand based on 110% of cost of production consequently lacked foundation.

Conclusion: The entities were not established to be related parties; the differential duty, interest and penalty on this count were unsustainable, in favour of the assessee.

Final Conclusion: The extended-period demand and the related-party valuation demand fail, while the declared Chapter 29 classification of Nicotine Sulphate prevails.

Ratio Decidendi: A disclosed tariff classification cannot attract the extended limitation period absent suppression, and Nicotine Sulphate, as a vegetable alkaloid derivative, falls under the alkaloid heading notwithstanding the general requirement of separate chemical definition in Chapter 29.
