Mica classification and limitation turn on tariff notes, independent evidence, and proof of suppression in past imports.

Tariff classification of imported mica depended on the tariff headings, HSN notes, physical examination and laboratory reports. Goods found to be processed beyond mere rifting and trimming, including mica mixed with polymer or additives, were classifiable under Tariff Item 68149090, and differential duty on the live consignments was upheld. Test results from two live consignments could not be mechanically extended to past imports without independent evidence of identical goods. As the Bills of Entry disclosed full particulars and there was no proof of collusion, wilful misstatement or suppression, the extended period of limitation failed, and the associated confiscation, redemption fine and penalties were set aside for the past consignments.

Issues: (i) Whether the imported goods under the live consignments were correctly classifiable under Tariff Item 68149090, and whether the CRCL report conclusively established that they did not fall under Tariff Item 25251090. (ii) Whether the test results of two live consignments could be applied to the past imports, and whether the extended period of limitation, confiscation, redemption fine, and penalties were sustainable.

Issue (i): Whether the imported goods under the live consignments were correctly classifiable under Tariff Item 68149090, and whether the CRCL report conclusively established that they did not fall under Tariff Item 25251090.

Analysis: The classification was determined by the tariff entries and the HSN notes. Heading 2525 covers crude mica and mica rifted into sheets, while Heading 6814 covers worked mica and articles of mica, including mica further worked than merely rifted and trimmed. The laboratory reports described the samples as mica that appeared to be processed, and one sample was mixed with polymer or additives. The physical examination, laboratory reports, and supporting material showed that the live consignments had undergone processing beyond merely rifting and trimming.

Conclusion: The live consignments were correctly classifiable under Tariff Item 68149090, and the differential duty confirmed on those consignments was upheld against the assessee.

Issue (ii): Whether the test results of two live consignments could be applied to the past imports, and whether the extended period of limitation, confiscation, redemption fine, and penalties were sustainable.

Analysis: Each Bill of Entry is a separate assessment, and the Department had not drawn samples from the past consignments. No evidence showed that all past consignments were identical in physical characteristics to the live consignments. The dispute was one of classification, and the record disclosed full particulars in the Bills of Entry without proof of collusion, wilful misstatement, or suppression of facts. Since the foundation for invoking the extended period failed, the confiscation and consequential penalties also could not survive.

Conclusion: The test results of the two live consignments could not be mechanically applied to the past imports, the demand on the past consignments was set aside, the extended period of limitation was held inapplicable, and the confiscation, redemption fine, and penalties were set aside in favour of the assessee.

Final Conclusion: The appeal succeeded only in part: the reclassification and duty demand were sustained for the live consignments, while the demands relating to the past consignments and all consequential confiscatory and penal consequences were set aside.

Ratio Decidendi: Classification must be decided on the terms of the tariff headings and relevant notes, and test results from one consignment cannot be mechanically extrapolated to other consignments without independent evidence; extended limitation requires proof of suppression or wilful misstatement.
