Tariff classification of EVA rubber sheets depends on proper statutory testing and reasoned adjudication on duty liability.

Micro cellular rubber sheets manufactured with EVA were discussed in the context of tariff classification between synthetic rubber and plastic goods under Chapter 40. The classification depended on the prescribed statutory tests, but the sample examined was drawn from finished goods rather than a proper sample meeting the conditions in Note 4, so the test report could not safely support the entry adopted. The adjudicating order also lacked adequate reasons on customer confirmations and duty quantification. The matter therefore required retesting of a proper sample and fresh, reasoned adjudication on classification, duty liability and the evidence, after hearing the assessee and following natural justice.

Issues: (i) Whether micro cellular rubber sheets manufactured with EVA were classifiable under sub-heading 4008.11 as synthetic rubber or under sub-heading 3921.19 as plastic goods; (ii) whether the test report based on samples drawn from finished goods could validly support the classification when Note 4 to Chapter 40 required testing of a proper sample free from prohibited materials; (iii) whether the demand and duty quantification, as well as the treatment of customer confirmations, required fresh adjudication in a speaking order.

Issue (i): Whether micro cellular rubber sheets manufactured with EVA were classifiable under sub-heading 4008.11 as synthetic rubber or under sub-heading 3921.19 as plastic goods.

Analysis: The classification turned on the correct application of Chapter 40 and the interpretative scheme in the tariff. Synthetic rubber, as explained in Note 4, includes certain rubber-plastic mixtures only if the prescribed vulcanisation, elongation and recovery conditions are satisfied. The material on record showed that the product contained natural rubber to a substantial extent, but the Revenue's case rested principally on test reports obtained from finished goods described as foam of EVA and plastic dominant. That approach did not, by itself, resolve the tariff entry where the relevant statutory notes required the product to be tested in the proper condition for determining whether it answered the description of synthetic rubber.

Conclusion: The classification could not be finally upheld on the basis of the record as it stood and required reconsideration after proper retesting.

Issue (ii): Whether the test report based on samples drawn from finished goods could validly support the classification when Note 4 to Chapter 40 required testing of a proper sample free from prohibited materials.

Analysis: The statutory notes and the explanatory material required a sample of the unvulcanised raw material, or a sample from which prohibited fillers, plasticisers and extenders had been removed, before the prescribed tests could be relied upon. The sample sent for examination was taken from finished goods, which could contain substances not permitted for the test under Note 4. In those circumstances, the reports obtained from the finished product could not furnish a safe basis for classification. The proper course was to obtain and test a correct sample in accordance with the tariff notes and the HSN guidance.

Conclusion: The test reports based on finished-goods samples were not sufficient to sustain the impugned classification.

Issue (iii): Whether the demand and duty quantification, as well as the treatment of customer confirmations, required fresh adjudication in a speaking order.

Analysis: The order had ignored the customer confirmations without adequate reasons and therefore suffered from a want of speaking treatment on that aspect. The quantification of duty was also required to be determined by the adjudicating authority itself and not delegated mechanically. Since the classification issue itself required fresh examination, the consequential duty computation had to be redone after affording a reasonable opportunity of hearing and following natural justice.

Conclusion: Fresh adjudication was required on classification, duty quantification and consideration of the evidence in a reasoned order.

Final Conclusion: The matter was sent back for retesting of a proper sample and for a fresh, reasoned adjudication on classification and duty liability, with hearing to the assessee and compliance with natural justice.

Ratio Decidendi: Where tariff classification depends on a prescribed chemical or physical test, the test must be conducted on a sample that satisfies the statutory conditions for the test, and a classification founded on an improper sample or an unreasoned adjudication cannot be sustained.
