Dutiability of refrigeration cooling coils upheld where site assembly did not change their character; limitation plea also failed.

Goods used as cooling coils in refrigeration technology were treated as parts of refrigerating machinery classifiable under Central Excise Tariff Item 29A(3), because the manner of site assembly did not alter their essential character and constructive removal for manufacture attracted duty. The plea that only specified exempt parts fell outside Rule 8 was rejected, and the goods remained dutiable. The limitation objection under Section 40(2) of the Central Excises and Salt Act, 1944 also failed, because that provision was held inapplicable to departmental proceedings and did not bar the show cause notice. The revision application accordingly failed on both classification and limitation grounds.

Issues: (i) whether the goods manufactured by the petitioners were classifiable as parts of refrigerating machinery under Central Excise Tariff Item 29A(3) and liable to duty; (ii) whether the proceedings were barred by limitation under Section 40(2) of the Central Excises and Salt Act, 1944.

Issue (i): whether the goods manufactured by the petitioners were classifiable as parts of refrigerating machinery under Central Excise Tariff Item 29A(3) and liable to duty.

Analysis: The goods were treated as cooling coils in refrigeration technology, notwithstanding the manner in which the pipes were arranged and welded at site. The reasoning proceeded on the basis that only specified parts were exempted under Rule 8 of the Central Excise Rules, 1944, while the goods in question fell within the tariff entry. The fact that the unit was assembled at site did not exclude duty, as the materials had been taken out for manufacture of the complete unit and amounted to constructive removal.

Conclusion: The goods were held dutiable as parts of refrigerating machinery under Central Excise Tariff Item 29A(3), against the assessee.

Issue (ii): whether the proceedings were barred by limitation under Section 40(2) of the Central Excises and Salt Act, 1944.

Analysis: The limitation contained in Section 40(2) was held inapplicable to departmental proceedings, and therefore the delay in issuance of the show cause notice did not bar the action.

Conclusion: The limitation plea was rejected, against the assessee.

Final Conclusion: The revision application failed on both the classification and limitation objections, and the departmental order was maintained.

Ratio Decidendi: Goods used as part of a refrigeration unit may be treated as dutiable parts of refrigerating machinery where the arrangement constitutes a cooling coil in trade and technical parlance, and the limitation provision invoked does not bar departmental proceedings.
