The AAR held that the imported diagnostic kits, being laboratory reagents in kit form, are correctly classifiable under Tariff Item 38221990 of the Customs Tariff Act, 1975, applying Rule 1 of the General Rules for Interpretation. The Authority rejected the applicant's earlier classification under CTI 38229090 as a bona fide error, noting absence of characteristics of certified reference materials and preferring the more specific heading. On exemption, the AAR ruled that the kits are not eligible for Basic Customs Duty exemption under Entry 102 of Notification No. 45/2025-Cus read with Entry 9 of List 3, as the benefit applies only to isolated Bovine Albumin, not composite diagnostic kits.
