In re FSP Technologies (CAAR Mumbai)
The Customs Authority for Advance Rulings (CAAR), Mumbai, considered an application filed under Section 28H(1) of the Customs Act, 1962 seeking an advance ruling on the customs tariff classification of imported filter cartridges used as replacement cartridges for filtering or purifying machinery for liquids or gases. The applicant imports and supplies fully assembled filter cartridges that are used as replaceable components in filtration systems across industries such as water treatment, gas purification, chemical processing, steam filtration and pharmaceutical manufacturing.
The products covered by the application consisted of Polymeric Media Filter Cartridges, Metallic Media Filter Cartridges and Sealed Capsule Filters. According to the application, these are complete filtration units comprising filtration media enclosed within supporting structures, end caps, seals, cages, cores and mounting interfaces, enabling them to be directly installed into filtration equipment. They are marketed and traded as filter cartridges, filter modules or replacement filters rather than as raw filtration media. The applicant stated that the cartridges are designed for use solely or principally with filtering or purifying machinery and are replaced during routine maintenance after becoming clogged or spent.
The applicant submitted that customs authorities had adopted differing classification practices by classifying such cartridges according to the constituent material, such as plastics, paper, textiles or metals. It contended that the imported goods are complete filter cartridges and should instead be classified as parts of filtering or purifying machinery under Customs Tariff Heading (CTH) 8421, specifically tariff item 8421 99 00. The applicant relied upon the wording of the Customs Tariff, Section XVI notes, Harmonized System Explanatory Notes, CBIC Circular No. 24/2013-Cus., international classification rulings, product design, engineering characteristics and commercial identity to support its classification. It also furnished additional submissions explaining the construction, components, intended use and technical characteristics of the goods, together with diagrams, product literature and physical samples.
