Trade parlance controls tariff classification; threaded insulator pins stayed in the residuary entry and extended limitation failed.

Insulator pins were classified under the residuary tariff entry because classification depended on common and trade parlance, and the goods were not shown to be understood in the market as bolts, nuts or screws. Mere threading did not make them fall within the fastener entry when their function was to support an insulator and they remained a distinct component. The extended period for recovery of duty was not invocable because the assessee had filed a declaration showing classification under the residuary entry, which negated suppression of material facts; departmental correspondence also indicated that the goods were earlier understood to fall under that entry.

Issues: (i) Whether insulator pins were classifiable under Tariff Item 52 of the old Central Excise Tariff or under Tariff Item 68; (ii) Whether the extended period of limitation for recovery of duty was invocable.

Issue (i): Whether insulator pins were classifiable under Tariff Item 52 of the old Central Excise Tariff or under Tariff Item 68.

Analysis: Tariff Item 52 covered bolts, nuts and screws of base metal, including specified allied articles, whereas Tariff Item 68 was the residuary entry. The deciding factor was the nature of the goods in common parlance and whether they were known in trade as bolts, nuts or screws. The record did not show that the insulator pins were understood as screw studs in the relevant technical or trade sense, and their main function was to support the insulator rather than to act as fasteners. Mere threading was not enough to bring them within Tariff Item 52 when the goods were recognisable as a distinct component and not as bolts, nuts or screws in the market.

Conclusion: The insulator pins were correctly classifiable under Tariff Item 68 of the old Central Excise Tariff.

Issue (ii): Whether the extended period of limitation for recovery of duty was invocable.

Analysis: The assessee had filed a declaration showing classification under Tariff Item 68, so there was no suppression of material facts. If the Department considered that classification to be incorrect, it could have taken corrective action on the basis of the declaration itself. The Departmental correspondence also showed that the goods were earlier understood to fall under Tariff Item 68, which negatived any allegation of wilful evasion.

Conclusion: The extended period of limitation was not invocable.

Final Conclusion: The goods were held to fall under the residuary tariff entry, and the duty demand could not be sustained for the extended period.

Ratio Decidendi: For tariff classification, goods must be identified by their common and trade parlance understanding, and mere threading does not place an article within a specific fastener entry unless it is recognised in the market as such; absent suppression, the extended limitation period cannot be applied.
