Alloy steel classification dispute defeats extended limitation and penalties where import description and export-linked exemption were bona fide.

API 5L PSL2 X70 and X80 grades were examined under Chapter 72, with Chapter Note 1(f) applied to determine whether the presence of niobium and molybdenum brought the goods within other alloy steel; the surrounding record and established clearance practice supported the importer's bona fide Heading 7208 claim. The advance authorisations and exemption notifications were treated as covering the imports in the factual setting, as the export-linked scheme contemplated duty-free inputs and the authorisation defect was curable. Alleged misdeclaration was not proved because the entry reflected a classification dispute, not suppression or dishonest statement, so extended limitation, confiscation and penalties were unsustainable.

Issues: (i) Whether API 5L PSL2 X70 and X80 grades were classifiable as other alloy steel under Chapter 72 or could be treated as non-alloy steel under Heading 7208; (ii) Whether the advance authorisations and exemption notifications covered the imported grades and supported duty-free clearance; (iii) Whether there was wilful misdeclaration warranting invocation of the extended period, confiscation and penalties.

Issue (i): Whether API 5L PSL2 X70 and X80 grades were classifiable as other alloy steel under Chapter 72 or could be treated as non-alloy steel under Heading 7208.

Analysis: Chapter Note 1(f) to Chapter 72 was applied to determine whether the presence of specified alloying elements brought the steel within the scope of other alloy steel. The imported grades contained niobium and molybdenum within the prescribed limits, and the record showed that identical grades had long been cleared under Heading 7208. The dispute also showed that API grades could exist in both alloy and non-alloy forms, and the tariff note did not support the view that all listed elements had to exceed the thresholds simultaneously.

Conclusion: The grades were held classifiable as other alloy steel when the specified element threshold was met, but the surrounding record and established practice supported the assessee's bona fide classification claim under Heading 7208 for the purpose of the present dispute.

Issue (ii): Whether the advance authorisations and exemption notifications covered the imported grades and supported duty-free clearance.

Analysis: The export item under SION C-593 was carbon steel submerged arc welded pipes of API grade, while the import item description was non-alloy HR coils/plates. The judgment noted that the Foreign Trade Policy contemplated duty-free import of inputs physically incorporated in export products, that the Norms Committee and DGFT authorities had taken curative or clarificatory action in related matters, and that the export obligation had been fulfilled in substantial measure. In that setting, the advance authorisations were treated as rectifiable and the customs exemption scheme was not defeated merely because the imported goods were later treated as alloy steel.

Conclusion: The advance authorisations and exemption notifications were held to support the assessee's claim to duty-free import in the facts of the case.

Issue (iii): Whether there was wilful misdeclaration warranting invocation of the extended period, confiscation and penalties.

Analysis: The declaration in the bills of entry was treated as a claim of classification rather than a dishonest misstatement, especially because the goods were described by generic API grade, the exact chemical composition was ascertainable only from mill test certificates, and the department itself had accepted similar clearances earlier. The absence of proven suppression or manipulation, the bona fide understanding in trade, the use of the goods in export production, and the lack of a sustained challenge to earlier assessments negatived the allegation of mens rea. On that basis, the extended period under section 28 and the consequential confiscation and penalties could not stand.

Conclusion: Wilful misdeclaration was not established, the extended period was not invocable, and confiscation and penalties were unsustainable.

Final Conclusion: The duty demand and all consequential penal and confiscatory consequences were set aside, and the appeals were allowed in favour of the importer-appellants.

Ratio Decidendi: Where imported steel grades have a long accepted classification practice, the exact alloy composition is not shown to have been suppressed, and the export-linked exemption scheme and authorisation regime support the import, a mere incorrect tariff claim does not by itself constitute wilful misdeclaration so as to sustain extended limitation, confiscation or penalty.
