Last updated: August 2026 dataAbrasive and functional powders derived from non-diamond precious and semiprecious stones — both natural and synthetic — are classified under the single tariff line 7105900000. Materials in this category include corundum (ruby/sapphire) powder, garnet abrasive, and similar stone-derived powders used in lapping, polishing, and waterjet cutting applications. Ireland and Austria lead US supply under this heading, a pattern that reflects European specialty abrasive and optical-component manufacturing rather than gem-trade flows.

Natural garnet used as an abrasive is generally classified under Chapter 25 (specifically heading 2513) as a natural abrasive, not under Chapter 71. Heading 7105.90 covers dust and powder derived from precious or semiprecious stones — a category that applies when the source material qualifies as a precious or semiprecious stone under Chapter 71 notes. Importers should confirm whether their specific garnet product meets that threshold or is more appropriately classified as a mineral abrasive.
Key end uses include precision optical polishing (corundum and synthetic sapphire powder for lens and wafer finishing), specialty lapping compounds for hard-material machining, and certain ceramic and refractory applications. The relatively concentrated supply from Ireland and Austria reflects the presence of specialty abrasive and optical-component manufacturers in those countries serving high-precision industrial customers.
