Specific tariff heading for liquid filters governs classification of irrigation sand and screen filters; broader exemption claim needs reconsideration.

Sand filters and screen filters used in irrigation systems are treated as filtering machinery for liquids and are classifiable under sub-heading 8421.00, not under sub-heading 8424.00, because the specific tariff heading for filters prevails over the more general irrigation machinery entry. The exemption question under Notification No. 46/94 was not fully examined on the broader claim under Serial No. 26, which covers parts of goods specified in the notification and falling under Chapter 84. That exemption claim requires fresh factual and legal consideration and was remanded for reconsideration.

Issues: (i) Whether sand filters and screen filters used in irrigation systems are classifiable under sub-heading 8421.00 of the Central Excise Tariff Act, 1985 or under sub-heading 8424.00; (ii) whether the goods are eligible for exemption under Notification No. 46/94, including the claim under Serial No. 26.

Issue (i): Whether sand filters and screen filters used in irrigation systems are classifiable under sub-heading 8421.00 of the Central Excise Tariff Act, 1985 or under sub-heading 8424.00.

Analysis: The goods were found to be filters whose function is to remove impurities from irrigation water. Sub-heading 8421.00 specifically covers filtering or purifying machinery and apparatus for liquids, while Section Note 2(a) of Section XVI requires parts falling within a specific heading in Chapters 84 and 85 to be classified in that heading. The claim that the goods should follow the heading of sprinkler irrigation machinery was rejected because a specific tariff heading existed for filters.

Conclusion: The goods are classifiable under sub-heading 8421.00 and not under sub-heading 8424.00; this issue is decided against the assessee.

Issue (ii): Whether the goods are eligible for exemption under Notification No. 46/94, including the claim under Serial No. 26.

Analysis: The lower authorities considered only Serial No. 20 of the notification, which applies to mechanical appliances of a kind used in agriculture or horticulture falling under sub-heading 8424.00. The broader claim under Serial No. 26, relating to parts of goods specified in the notification and falling under Chapter 84, was not examined. Since this claim required factual and legal consideration, the matter had to be reconsidered by the appellate authority.

Conclusion: The exemption claim under Serial No. 26 was not finally decided and was remanded for fresh consideration.

Final Conclusion: The tariff classification was upheld under the filtering machinery entry, but the exemption issue was sent back for reconsideration on the broader notification claim.

Ratio Decidendi: Where a product answers to a specific tariff heading by its function, that specific heading governs classification, and an exemption claim not examined under the relevant wider entry must be reconsidered on remand.
