Sintered filter media classified as machinery parts, not wire cloth, with notification benefit upheld for filtration equipment.

Sintered filter media imported for viscose filtration machinery was held classifiable under Heading 8421.99 as parts of filtering or purifying machinery, not under Heading 7314.11 as wire cloth, because the sintering process gave the article a distinct structure, fixed pores, and filtering function beyond ordinary wire cloth. The Tribunal treated the bonded and integrated product as a machinery part within the exclusion to Heading 7314 and relied on the explanatory material supporting Heading 8421 for filtering machinery and its parts. The goods were also found eligible for the notification benefit attached to Heading 8421.99, so the departmental classification was displaced and the assessees succeeded.

Issues: Whether sintered filter media imported for use in viscose filtration machinery was classifiable under Heading 8421.99 as parts of filtering or purifying machinery, or under Heading 7314.11 as wire cloth, and whether the goods were entitled to the notification benefit attached to Heading 8421.99.

Analysis: The goods were not to be viewed as plain wire cloth merely because a stainless-steel backing formed part of their structure. The material placed before the Tribunal showed that the sintering process created a distinct, highly sophisticated filtering medium with fixed pores and special filtering properties, giving the article a character and use different from ordinary wire cloth. The exclusion in Heading 7314 for wire cloth made into machinery parts by assembly with other materials was treated as extending to the present bonded and integrated product, while the explanatory material for Heading 8421 supported classification of filtering machinery and its parts. The Tribunal also accepted that the imported article functioned as a part of viscose filtration machinery and that the relevant notification covered goods classifiable under Heading 8421.99.

Conclusion: The goods were classifiable under Heading 8421.99 and not under Heading 7314.11, and the assessee was entitled to the consequential notification benefit.

Final Conclusion: The classification adopted by the department was displaced, the impugned orders were set aside, and the assessees succeeded in the appeals.

Ratio Decidendi: A sintered article that acquires a distinct functional and structural character as a part of filtering machinery is to be classified as a machinery part under the heading applicable to the machinery, rather than by reference only to its constituent metal base.
