https://www.taxtmi.com/highlights?id=96112 The sole issue is tariff classification under Heading 9021: whether the Onyx embolization system is an "artificial part of the body" (CTI 9021 31/39) or an implanted appliance compensating for a defect (CTI 9021 90 90). Applying GRI 1 and Explanatory Notes, the authority finds classification turns on anatomical replacement: artificial parts must substitute or replicate body structure. The Onyx system occludes vascular defects to induce thrombosis and does not replace or restore anatomical structure; therefore it is not classifiable under 9021 31/39 and is held classifiable under CTI 9021 90 90. - AAR en-us Sat, 17 Jan 2026 11:42:12 +0530 Sat, 17 Jan 2026 11:42:12 +0530 TaxTMI RSS Generator https://www.taxtmi.com/highlights?id=96112 The sole issue is tariff classification under Heading 9021: whether the Onyx embolization system is an "artificial part of the body" (CTI 9021 31/39) or an implanted appliance compensating for a defect (CTI 9021 90 90).
